Podcast
TL;DR
  • Substrate is a semiconductor moonshot that founder James Proud has described as having 1% odds, while its potential payoff has become large enough to attract financing. The company claims particle-accelerator-powered X-ray lithography could halve manufacturing costs, eliminate some multi-patterning, and produce high-resolution layers comparable to those of leading foundries. Ben Thompson remains explicitly uncertain—“It’d be nice to see more evidence”—but highlights Proud’s posture of operating with “100% conviction” despite the long odds.

  • Trying to disrupt ASML and TSMC simultaneously sounds absurd, yet the industry’s integration makes that strategy internally coherent. Thompson argues that lithography is the central step around which the entire fabrication process is optimized, so a radically different tool probably cannot simply be dropped into an incumbent fab. Substrate can buy conventional etching, coating, and doping equipment, but probably must rebuild how those pieces work together “from first principles.”

  • ASML and TSMC’s co-evolution created formidable incumbent lock-in. Lithography now represents perhaps 30%-35% of fabrication cost; Thompson roughly estimates current machines near $250 million and the next generation closer to $500 million, while stressing that he is “pulling these numbers out of my rear end.” A roughly $30 billion fab that is not filled and running leaves its owner in serious trouble, making TSMC “almost the brake on the AI bubble” because it bears enormous upfront equipment risk.

  • The strongest defense of today’s AI bubble is not durable GPUs but coordinated invention across many improbable projects. Big Tech spending flows through NVIDIA to TSMC and ASML, while simultaneously making outsiders such as Substrate financeable: “A lot of people working on a lot of hard problems all at the same time.” Thompson expects excess and failures, yet argues that the future will depend on what “emerges from the rubble” and could not otherwise have been attempted.

  • A thermodynamic chip promising theoretically 10,000-times-more-efficient image generation is the episode’s best specimen of bubble-enabled experimentation. Its proposed mechanism excites a chip according to a probability distribution, then uses the system’s physical decay to compute probabilistic outputs. It sounds “totally insane,” but Thompson sees a conceptual fit between probabilistic AI and probabilistic hardware that could better align computation with probabilistic outputs than today’s binary, deterministic chips.

  • Semiconductor controls, ideological ambition, and AI mania are all forcing functions against industrial stasis. Thompson says a new US foundry would otherwise go bankrupt “100 times over” while descending the learning curve; chip controls instead motivate China to absorb uneconomic development costs, while without them TSMC could “rule the roost forever.” Breaking that equilibrium may require “religious fervor”: Substrate is ideological about the US winning, while AI companies act as if they are “inventing God.”

Digest · the substance, structured for research

1. Substrate’s X-ray wager is plausible enough to examine, not proven enough to endorse

  • Andrew Sharp frames Substrate’s claim precisely: channel light from a particle accelerator through a car-sized tool, print layers comparable to those of leading foundries, and cut semiconductor manufacturing costs in half. Thompson’s answer to whether it has legs is deliberately blunt: “I don’t know.”

  • X-ray lithography itself is not new. EUV reduced the width of light to 13 nanometers, but still requires extraordinary mirrors and sometimes multi-patterning; every additional pass adds complexity and cost. X-rays are theoretically thinner, potentially removing that repetition and lowering costs.

  • The unresolved questions are load-bearing: whether Substrate has achieved a consistent X-ray source, whether radiation disrupts other fabrication steps such as doping, and whether problems that confronted the approach in the 1980s and 1990s have genuinely been overcome. An old idea becoming viable 40 years later is “totally plausible,” not established.

  • Proud himself reportedly told investors there was a 1% chance of success but said he would operate with 100% conviction; he suggested the percentage had risen somewhat as breakthroughs emerged. Sharp found him more credible for frankly acknowledging the odds.

  • Thompson acknowledges criticism that his Proud interview lacked technical pressure, but says the relevant details were never going to be disclosed: “To the extent there’s something real, it is obviously a massively valuable secret.”

2. ASML won by optimizing the system, not merely selling a better machine

  • Thompson traces ASML’s ascent against Canon and Nikon to its partnership with TSMC, contrasting that relationship with Nikon’s alignment with Intel. “The rise of TSMC is the rise of ASML, and vice versa.”

  • The shift from 200-millimeter to 300-millimeter wafers captures the difference. Intel could tolerate less attention to throughput and yields because its monopoly margins covered inefficiency; ASML and TSMC redesigned the process together so larger wafers moved fast enough to deliver their intended volume gains.

  • Lithography now accounts for roughly 30%-35% of the cost, according to Thompson, while foundries are in the $20 billion range and the next generation may cost $30 billion-$50 billion. He roughly put current machines near $250 million and the next generation near $500 million, while warning that he was “pulling these numbers out of my rear end.” A $30 billion fab that is not filled and running leaves its owner in serious trouble, which is why he called TSMC “almost the brake on the AI bubble.”

  • A Taiwan earthquake—2001, Thompson believes—became another inflection point: ASML helped restore TSMC’s machines within weeks, while Japanese equipment took months. ASML later did the difficult commercialization work on EUV and became the only supplier capable of making those machines.

3. Replacing lithography may require rebuilding the foundry around it

  • Sharp’s pushback is the obvious one: Proud is proposing to disrupt both ASML and TSMC, despite two decades of failed challenges to either company. “That seems very ambitious.”

  • Thompson’s rebuttal is architectural. Lithography is the most expensive, complex, precision-dependent fabrication step, and every surrounding process has been tuned to it—much like the Windows-Intel partnership. Substrate need not reinvent etching or doping equipment, but radically changing the center means reintegrating everything around it.

  • Incumbent strength may create the opening. TSMC and Intel possess enormous expertise in the existing method, yet are “pot committed” to it; Thompson sees little chance that TSMC could seriously pursue a wholesale alternative while meeting current demand. Dominance makes a completely new approach more viable because “there’s not gonna be a response.”

4. Bubble economics coordinates inventions that normal markets would reject

  • Thompson used to associate bubbles primarily with waste and reputational danger. Something like Pets.com exists today, but it took 20 years, a recession, and a “cold frost ice age in tech” for the underlying model to emerge.

  • The conventional productive-bubble payoff is stranded infrastructure: bankrupt railroad builders still leave tracks, failed telecom companies leave dark fiber, and power investment can leave plants operating for 50 or 100 years. GPUs lack that longevity, creating a harder question about what today’s durable residue will be.

  • His newer framing, drawn from Byrne Hobart’s Boom, is “coordinated creation, coordinated innovation, coordinated invention.” Tech companies’ tens or hundreds of billions flow into NVIDIA, then TSMC and ASML, while the scale of the opportunity supplies capital for many interdependent experiments whose successes might justify many failures.

  • The thermodynamic-chip example carries the argument: excite a chip according to a chosen probability distribution, let it decay toward neutral energy, and use that physical process for computation. The claimed theoretical result—image generation 10,000 times more efficiently—might fail, but “in a normal period, no one” would fund the attempt.

5. A probabilistic technology cycle demands probabilistic analysis

  • Thompson expects the mania to break: “At some point we’re gonna say, ‘Wow, we got a little crazy then.’” He nevertheless thinks it is “almost certainly” true that valuable technologies will emerge from the wreckage only because the bubble funded them.

  • That changes his own analytical posture. Stratechery’s first decade offered relatively deterministic chains—Aggregation Theory, stable Big Tech lanes, A-to-B-to-C reasoning—but today he is attempting “deterministic analysis on top of probabilistic outcomes.” Whether Proud succeeds is unknowable; whether it is important and valuable that someone is attempting it feels much clearer.

  • The geopolitical version of the same mechanism is chip controls, which motivate China to absorb development costs that ordinary economics would reject. Substrate’s declaration that it is “an ideological company” and thinks the US should win invites demands for technical proof, but Thompson argues that difficult breakouts can require the same “religious fervor” driving AI companies to spend as though they are “inventing God.”

Andrew Sharp

Hello, and welcome to a free preview of Sharp Tech. Hello, and welcome back to another episode of Sharp Tech. I’m Andrew Sharp, and on the other line, Ben Thompson. Ben, how are you doing?

Ben Thompson

I’m doing fantastic. You look great, Andrew. Why do you look so good today?

Andrew Sharp

Coming in nice and crisp today. A lot of good things happening in the Sharp Tech universe. You want to tell the people?

Ben Thompson

I have fiber. We have functional internet.

Andrew Sharp

No, no, no. I think the thing to emphasize is that Ben didn’t have fiber internet for the last month or two, and so in some of the recording sessions, we were dealing with internet from 10 or 15 years ago. But now we’re coming in high-def, with no interruptions to any of the podcasts. I’m very excited about the future.

Ben Thompson

No, you understate how dire the situation was. I acquired—I bought the location that I’m at because one of my best friends literally lives next door. This, actually, I learned totally by accident. I moved into a place in Taiwan to be closer to the kids’ school.

Andrew Sharp

Mm-hmm.

Ben Thompson

I moved into a place in Taiwan. Everything is a condo, right? You’re all in sort of high-rises. We’re in a 15-story building. The building we’re in has two units per floor. Literally next door ends up being this other guy from Wisconsin, who ends up becoming one of my best friends. We still hang out all the time. You’ve had the pleasure—

Andrew Sharp

I’ve met him.

Ben Thompson

Yeah.

Andrew Sharp

He’s great. It’s amazing that you ran into each other like that.

Ben Thompson

It is.

Andrew Sharp

Yeah.

Ben Thompson

And I realize, actually, a real fundamental key to happiness is, in fact, location, location, location.

Andrew Sharp

Mm-hmm.

Ben Thompson

Now, usually location is about weather, and I think weather does contribute to happiness. You should ask for an update on my weather feelings in 2 to 3 months.

Andrew Sharp

Yeah. We’ll check back in February to see where your head’s at there.

Ben Thompson

But the other one is being close to friends, which is fantastic. So I got a house that is literally next door to one of my best friends. I did not think about or look into the internet situation at this house.

Andrew Sharp

Mm.

Ben Thompson

This particular neighborhood was built 30 years ago or so, which means most of the people here are older at this point and maybe don’t appreciate what their expectations should be as far as internet goes. It’s a little bit remote, and their only option is the local cable company. The local cable company knows they’re the only option. There is fiber sort of across the street. I heard they built that out. Very few people took it up, I think, because of the dynamics that I’m talking about, so they just stopped building.

So I’ve basically had nonfunctional internet. I talked to technicians. I’ve had multiple technicians come over. They’re like, “Yeah, your neighborhood’s totally saturated.”

Andrew Sharp

Impressively dysfunctional internet. Not just slow internet, but internet that would shut off inexplicably—

Ben Thompson

No. It goes down multiple times a day, all the time.

Andrew Sharp

And just be down for 45 minutes—

Ben Thompson

Usually only for a few seconds.

Andrew Sharp

Yeah.

Ben Thompson

Going down for a couple of seconds is not great for recording a podcast, okay?

Andrew Sharp

Yeah.

Ben Thompson

So it’s not a few months—it’s been a while since I’ve been here. You actually had to remind me, “Make sure you switch to Starlink before every podcast.”

Andrew Sharp

Yep.

Ben Thompson

Because at least it’s reliable, even if theoretically the speeds are not. So, first up, I love Starlink. God bless Elon Musk.

Andrew Sharp

Thank you, Elon.

Ben Thompson

Yeah.

Andrew Sharp

Yes.

Ben Thompson

No, it’s amazing. I have one on my house. I have a portable one that I’ve talked about before, using it around. But yeah, it’s absolutely, again, another example to get me back on the sort of anti-monopoly train, albeit a real sort of monopoly with wires in the ground—

Andrew Sharp

Wires in the ground.

Ben Thompson

—and when there’s one option, they don’t need to fix it and make it better. So I’ve really spent an unfortunate amount of money. The way you can get fiber, you’re not going to get it from AT&T or whoever. However, there are business fiber companies that will build out to various locations if you’re willing to pay for it.

Andrew Sharp

Mm-hmm.

Andrew Sharp

Yeah. Well, you’re running a business over there—

Ben Thompson

I am.

Andrew Sharp

—in addition to living next to your best friend.

Ben Thompson

Yes.

Andrew Sharp

So it makes sense, and here we are.

Ben Thompson

It’s funny, though. I did appreciate and love every time that our podcast cut out for the last 3 months, because it just reaffirmed that this ungodly amount of money that I was spending was going to be worth it.

Andrew Sharp

It’s funny because I would try to tell you, “It’s not that bad,” and you were like, “Don’t tell me that.” Then I would have the freedom to be honest and be like, “Ben, I didn’t hear what you were saying for about 4 minutes of that podcast.”

Ben Thompson

Well, maybe this is going to be a big problem for you. You’re going to have to have some accountability to actually listen to my ramblings when I’m going on a monologue.

Andrew Sharp

There you go. A lot of pressure going forward.

Ben Thompson

But yes, back in the world of fiber, sincere thanks to Starlink. It has basically made Stratechery and Sharp Tech possible for the last 5 to 6 months. As good as it is, it does not compare to the clarity that we have right now. It’s amazing.

Andrew Sharp

Mm-hmm.

Ben Thompson

Yes.

Andrew Sharp

It’s great.

Ben Thompson

Yes.

Andrew Sharp

One other question on your house: This is your first Halloween back in America. Are you prepped for the neighborhood? I feel like you’ve got a couple [?].

Ben Thompson

Full-size candy bars, baby. Full-size candy bars.

Andrew Sharp

You go full-size?

Ben Thompson

Absolutely.

Andrew Sharp

Wow.

Ben Thompson

You’ve got to make a good first impression.

Andrew Sharp

Good.

Ben Thompson

Yes.

Andrew Sharp

Good to hear. I love it. I’ll be trick-or-treating more than handing out candy with Charles, who’s about 2 and a half years old. I’m very excited for his first real trick-or-treating adventures.

Ben Thompson

My son was asking, “I’ve never really gone trick-or-treating.” I mean, they had it in Taiwan. The building always had it, so you’d go up and down the floors and get it. Then there’s one in the neighborhood where we’re at called Tianmu.

Andrew Sharp

Okay.

Ben Thompson

All the stores will have stuff. It’s not quite the same as sort of walking down a busy street and going to a convenience store and getting some piece of Hi-Chew or something like that.

Andrew Sharp

Yep.

Ben Thompson

The AIT, the sort of American embassy, had a neighborhood up on the top of Yangmingshan with traditional houses, and you could—

Andrew Sharp

Ah.

Ben Thompson

—actually go door to door. But again, it was very much a case of, “This is a thing you’re going to do.” The idea of just going door to door in your neighborhood and it being sort of a thing—yeah, it was remarkable. You’re like, “I’ve never done that before.” It was kind of interesting. It’ll be cool.

So, do you do the Christmas light decoration thing, by the way?

Andrew Sharp

What’s that?

Ben Thompson

Do you decorate your house with Christmas lights?

Andrew Sharp

Oh, well, yes. I was wondering whether there was some special Christmas light thing. Yes, I do put Christmas lights on the house.

Ben Thompson

Okay. No, just thinking about planning. It’s very funny where all this stuff that is very normal, I’m sort of considering for the first time. So yeah.

Andrew Sharp

A whole new world here in the United States of America.

1. Substrate Challenges Chip Manufacturing

Speaking of the United States of America, we’re going to begin the show with a note from Greg, who wrote in Wednesday responding to a digression of yours on the last episode as we were discussing American resilience. Greg writes, “It’s time for some American ingenuity, huh? Ask and you shall receive.” Then he links to Substrate.com before asking, “Does this have any legs?”

Ben, as fate should have it, you interviewed the CEO of Substrate this week. Delightful conversation. We’ll put a link in the show notes for people. And for anybody who hasn’t been following the news, Substrate is a company that claims to have developed an alternative manufacturing process for semiconductors that would cut the manufacturing cost in half by channeling light from a giant instrument known as a particle accelerator through a tool the size of a car. That technique would allow Substrate to print a high-resolution microchip layer comparable to images produced by the world’s leading foundries. I’m cribbing from The New York Times for that synopsis, but more importantly, Substrate is an American company. What do you think? Does it have legs? Does this idea have legs?

Ben Thompson

I don’t know.

Andrew Sharp

Responsible answer.

Ben Thompson

Yeah. It’s really interesting because I got some pushback on this interview saying, “You didn’t push on any technical details. There are so many things that are going to go into this,” all of which are fair and appropriate. Part of the reason I’m not getting too much into technical details is that he wasn’t going to share any of them.

Andrew Sharp

He couldn't, right. Yeah.

Ben Thompson

Well, yeah. To the extent there's something real, it is obviously a massively valuable secret, whatever they've figured out.

Andrew Sharp

Mm-hmm.

2. Lithography Drives Chip Costs

Ben Thompson

The concept of X-ray lithography is not new. One of the weird things is that we talk about 1-nanometer, 2-nanometer, and 3-nanometer chips, which is mostly a marketing term. Basically, the idea is that the width of the lines you're drawing and the distance between the lines are getting smaller and smaller all the time.

Andrew Sharp

Yeah.

Ben Thompson

The big breakthrough was EUV, which reduced the width of light to 13 nanometers. It's like, wait, actually, the light is wider than the lines? Yes, that is true, in the way that it's happening. But what happens is they do this crazy focusing with all these mirrors, and even when they get smaller, they sometimes have to go over a chip multiple times, called multi-patterning. Every time we do that, it's more complex, it's more expensive, and there are all these sorts of challenges.

Lithography has come to be by far the most difficult and most expensive step in the process. It's the number-one driver of why foundries are getting more and more expensive. We're in the $20 billion range. The next generation, we're going to be in the $30 billion to $50 billion range. I think, as you know, it might be in the $30 billion range right now.

Andrew Sharp

And when we say lithography, we're talking about ASML, effectively, right?

Ben Thompson

Yes. They dominate the space. The story of how they came to dominate it is that it used to be Canon and Nikon. I think particularly Nikon was big in this space. They were very closely aligned with Intel.

There was a period when ASML was the upstart, and ASML and TSMC have always been sort of hand in hand. The rise of TSMC is the rise of ASML, and vice versa. A big factor—I think I might have talked about this on the podcast previously—was the shift from 200-millimeter wafers to 300-millimeter wafers.

Andrew Sharp

Mm-hmm.

Ben Thompson

The physics of it changed. They're larger, right? Intel basically didn't care. This actually came up on the Intel earnings call, where the CFO said, "To be honest, we didn't really care about yields before."

Intel was always so far ahead and had such a monopoly and could charge such high prices that they didn't really need to care about throughput and efficiency. As long as it was good enough and they got the levels they needed, they could charge high prices and it would sort of pay for itself.

Andrew Sharp

Mm-hmm.

Ben Thompson

One of the huge challenges they have in becoming a foundry is that you have to maximize throughput. You have to get as much stuff through as possible. Your yields have to be high so that you can be competitive on pricing. You're not internalizing everything; you have to charge a competitive price relative to TSMC or whatever it might be.

Andrew Sharp

Right.

Ben Thompson

Their throughput was never actually that high—how many chips were going through per hour or per day, or whatever it might be. This is going back about 20 years. When you had this shift, the Nikons of the world—I can't remember whether it was Canon or Nikon that was the big one at the time—said, "Sure, we'll do bigger wafers." But they didn't rework the entire process.

If you're moving a larger wafer, you just do it more slowly because of the centrifugal forces and things like that. ASML actually completely reworked how their machines worked, hand in hand with TSMC. It's a new wafer, a new size; you have to rethink the whole thing so it can go through faster, so you can actually achieve the benefits of having a much larger wafer, which you can put more chips on.

If that larger wafer goes through much more slowly, which is basically what was going on at Intel, you're not getting any gains. You're just doing a bigger wafer more slowly. ASML and TSMC completely reworked this process to get the volume and the gains from going through it. There are other sorts of stories here.

Andrew Sharp

More volume and better yields. Yeah.

Ben Thompson

Yeah.

Andrew Sharp

It's kind of unbelievable.

Ben Thompson

There was a big earthquake in Taiwan in 2001, I believe it was. ASML got in there with TSMC and got the machines up and running in a matter of weeks. The Japanese machines took months. That was another sort of moment of this shift in balance and power.

All this culminated with ASML buying some of the critical technology for EUV way back when. We already discussed this. The idea came from Japan, actually. A lot of it was propagated by Intel and the U.S. government. ASML did the hard work to bring it to market, and now it's totally dominant. No one else can make an EUV machine, but they're extremely expensive.

Andrew Sharp

I was going to ask: Ballpark, are we talking about $200 million?

Ben Thompson

I was like $500 million for the high... I think the current ones are around $250 million, but the next generation are closer to $500 million. I'm pulling these numbers out of my rear end, so—

Andrew Sharp

And the foundry needs, like, 10 of those lithography machines?

Ben Thompson

Yeah, you need a bunch of them, right? And so—

Andrew Sharp

Yeah.

So that's where the cost is in all of this.

Ben Thompson

Well, everything's expensive, to be clear, but the biggest center of cost, for sure, is lithography. I think it's around 30% to 35%, and that's much higher than it used to be.

The idea here is, what if we could do this instead of using blowing up tin, creating this artificial light, focusing it through these crazy mirrors, and drawing these lines? What if we could use X-rays to do this instead?

Andrew Sharp

Mm-hmm.

Ben Thompson

It's actually even thinner, so theoretically you don't need to do multi-patterning, and it can just be cheaper overall. Now, a lot of the details are unclear, like I said, in terms of how it's going to work. The big question for X-rays has been a consistent light source, or a consistent source of X-rays, which they claim they're getting.

Andrew Sharp

Okay.

Ben Thompson

They're using a particle accelerator to do it, which sounds absolutely crazy. There are questions about the X-rays breaking through and disrupting things. Does it interrupt the doping process, where you're actually infusing these transistors to make them more performant? There are all these open questions about X-rays that were faced in the '80s and '90s, and it was decided that ultraviolet light was actually a better solution with these mirrors and these optics.

That's where the industry went. Now, this theory—that it was an idea that didn't work 40 years ago but might work today—I think in principle is totally plausible.

Andrew Sharp

Yeah.

Ben Thompson

I also think it's totally plausible that no one in the current semiconductor chain is going to go in this direction because they're all pot-committed to the way things work today, and they're under pressure as it is to make more and do more.

TSMC, as I wrote about this week, is kind of almost the brake on the AI bubble. Yes, they're building a ton and trying to support this. If this whole thing were to pop, they're the ones holding the bag because they're paying all this money for all this equipment.

Andrew Sharp

A lot of upfront investment based on the ecosystem exactly the way it is today.

Ben Thompson

Right. It just—I mean, if it costs $30 billion to build a fab and that fab is not filled and not running—

Andrew Sharp

Yeah.

Ben Thompson

—you are in big trouble. So this idea, number one, that an old idea could be possible today when it wasn't possible previously makes sense to me.

Andrew Sharp

Mm-hmm.

Ben Thompson

The idea, number two, that no one in the current chain is going to do it also makes sense to me. And this idea that if you're going to do it, actually you need to not just make a lithography machine but be a foundry also makes sense because it—

Andrew Sharp

So you say that makes sense. I'm very curious, because that's where I found myself raising an eyebrow. James Proud explained it to you, but Substrate—they're not only—

Ben Thompson

James Proud, yes.

Andrew Sharp

James Proud, excuse me. They are not only trying to disrupt ASML but also TSMC. That seems very ambitious, and everybody—

Ben Thompson

It does.

Andrew Sharp

—who's tried to displace either one of those companies has failed over the last 20 years. So why? Why are they building a foundry in addition to this lithography tool?

3. Substrate Must Rebuild The Foundry

Ben Thompson

Well, the key step—this is where I go back to that TSMC and ASML hand-in-hand partnership—is that the entire process has been optimized around this central step of lithography. It's the most expensive piece. It's the most complex piece. It requires the most precision, and everything sort of fits in around that.

If you're going to replace that, it makes sense that you actually have to rework the whole process, even if most of the steps are still the same. Those steps—you can buy the equipment.

It’s not like they’re going to reinvent etching machines, masking machines, or doping machines, or all these sorts of bits and pieces. But we already know the makers of these machines are happy enough to sell to whoever. The whole point is they’re selling to China. You’re using a lot of the same machines for trailing-edge chips as you are for leading-edge chips. Etching is going to happen at 20 nanometers, 14 nanometers, or 2 nanometers. Same thing—

Andrew Sharp

Yeah.

Ben Thompson

—with a lot of these chemical coatings, all these parts. So it’s not that they’re going to reinvent every step, but if the key step is completely new, the way all that other stuff integrates into the process, it makes sense it would need to be reworked. And TSMC and ASML, it’s kind of like Windows and Intel, to an extent. It’s this hand-in-hand partnership that makes this all work, and if you’re tearing out one piece, you probably can’t just drop it into TSMC. And if you’re Intel—

Andrew Sharp

Mm-hmm.

Ben Thompson

Even if you’re behind, all your expertise is still on the old way of doing things. Are you going to completely rework this? It makes sense you sort of have to start from first principles.

Andrew Sharp

Yeah.

Ben Thompson

It’s also totally insane, right? And the chances of success seem—number 1, does the X-ray lithography even actually work? Have they actually overcome all these problems? It’d be nice to see more evidence than we got, just to be totally honest.

Andrew Sharp

Mm-hmm.

Ben Thompson

And number 2, are you biting off more than you can chew, right? On one hand, it makes sense that a Thiel Fellow who’s most well known for creating a sleep tracker would take someone totally on the outside—

Andrew Sharp

You would need fresh eyes.

Ben Thompson

—that’s kind of crazy to do this.

Andrew Sharp

Yeah.

Ben Thompson

On the other hand, this is the guy who’s going to do this, right? So—

Andrew Sharp

Well, I will say for the record, James Proud was pretty honest about it. He recounted conversations with investors and said, “There’s a 1% chance this will succeed, but I’m going to operate with 100% conviction that it can’t fail.” He said maybe the percentages have gone up a little bit since then as some of the technology breakthroughs have come through. But by the same token, I found him more credible by his frank acknowledgment of how long the odds are for any of this to work.

Ben Thompson

For sure. So why talk to him now? I mean, there’s an element of press—why are you discussing it? He’s like, “Well, this is not going to be a secret for much longer anyway.”

Andrew Sharp

Mm-hmm.

Ben Thompson

There’s also a bit where I’m sure they’re going to be raising money soon. I’m sure this is tied to it. Was Chetecri basically used as a vehicle to help them raise money? Probably. But number 1, I’m certainly cheering for him.

Andrew Sharp

Yeah.

Ben Thompson

That’s, you know, I want to see that succeed. But—

Andrew Sharp

Not only that, but on the last episode, when you were talking about potential breakthroughs in the way we make chips, I recall thinking, on this end of the line, I mean, yeah, it’s great to want things. I don’t know why you would ever mention that, because for me, it’s a good reminder that the technology we have today is not fixed. It’s easy to forget that all of this can evolve, and has, when you look at the history of technology over the last 40 or 50 years.

It does make sense that the tech will be in a different place 10 or 15 years from now. Or—

Ben Thompson

It—

Andrew Sharp

—at least could be.

4. Bubbles Coordinate Innovation

Ben Thompson

It does. And a topic we’ve come back to a couple of times over the last few months is that it’s so fascinating to be in a bubble. I was aware of the bubble in the ’90s. I wasn’t working in tech; I was consuming lots of stuff that was coming from the bubble, often to my financial benefit, because all these people were insane. But to actually feel the dynamics internally—

Andrew Sharp

Mm-hmm.

Ben Thompson

Bubbles, we intrinsically, I think, attribute a negative connotation to them. You feel this as an analyst: “Should I write about this knowing that it could pop tomorrow, and then you look like a dummy because you supported stuff and then it blew up?” Even if you know intellectually this will pay off in the long run, right? I was just—

Andrew Sharp

Yeah.

Ben Thompson

—I was just talking to John on Dithering: Pets.com truly exists today. It also took 20 years, a massive recession, and a total, total dead, cold-frost ice age in tech. Bubbles are viewed negatively. And there is the theoretical construct—the Carlota Perez construct—of productive bubbles.

Andrew Sharp

Mm-hmm.

Ben Thompson

We’ve also talked about this. What is going to be the productive payoff from this bubble? Ideally, it’s power generation. We actually spend tons of money on power generation. All the investment that goes into it ends up being kaput, and people go bankrupt, but hey, we have power plants that run for 50 years or 100 years, or whatever it might be, and that is going to be a positive effect, right? The railroad tracks were a huge benefit, even though everyone building the railroad tracks went bankrupt.

My beautiful fiber probably at some point is touching some dark fiber that was laid in the late 1990s. It’s amazing, and it’s great, and we have a great video podcast, right? I appreciate WorldCom and everyone else that went bankrupt back in the day.

Andrew Sharp

Yep.

Ben Thompson

What is that going to be today? You have GPUs that aren’t going to last for 50 years, right?

Andrew Sharp

Mm-hmm.

Ben Thompson

And how are we going to get the productive angle? This is where I keep coming back to Byrne Hobart’s book, which was also about bubbles. He called it Boom. We discussed it. I had an interview with him.

What I got from the book originally, but didn’t feel until really recently, is that one of his points is the function of a bubble isn’t just this infrastructure investment. It’s coordinated creation, coordinated innovation, coordinated invention.

Andrew Sharp

Yeah.

Ben Thompson

Basically, you have a lot of people working on a lot of hard problems all at the same time. A lot of the ones that succeed are going to pay off the other ones. Everyone’s really dependent on everyone else also inventing things at the same time.

And you have, this week, this discussion of this creation. You also have all these tech company earnings where they’re like, “Yeah, you thought we were spending a lot last year?” “Full speed ahead. We’re spending even more.” And that spending—a lot of it’s going to NVIDIA. NVIDIA—some of that money is going to TSMC. A lot of that money to TSMC is going to ASML.

And there’s so much money coming in that it is suddenly making someone like Proud and Substrate seem—

Andrew Sharp

Yeah.

Ben Thompson

—why not? Yeah, it might be a 1% chance, but the payoff of that 1% is getting so astronomically large that here’s all the money you need to do it.

You have this new chip that was just announced this week. There’s this thermodynamic chip where you excite the chip according to a probability distribution that you want. As it decays and goes back to a neutral energy level, it’s actually doing computation according to a probability curve that you set it to, and you can do things like image generation, at least in theory, 10,000 times more efficiently than you can on chips.

And you think about it: We’ve talked about the idea that our chips today, even GPUs, are 1s and 0s. They’re binary computers, and it’s kind of weird we’re using binary deterministic computing for probabilistic outputs, which is what AI is. The idea, in theory, that you’ll have a probabilistic chip that actually uses natural forces, uses—

Andrew Sharp

Mm-hmm.

Ben Thompson

—thermodynamics to do computation, of course that’s going to be dramatically more efficient. Of course that could align with probabilistic computing to have a probabilistic decay in this chip that is actually doing your computation. It also sounds totally insane. Who’s—

Andrew Sharp

Yes.

Ben Thompson

—going to actually spend the money to do this? In a normal period, no one is.

Andrew Sharp

Yeah.

Ben Thompson

In a bubble, when companies are spending tens of billions, hundreds of billions of dollars, you have all this crazy going wrong. Suddenly, all this insanity seems more viable. And yes—

Andrew Sharp

So it pulls the investments forward; it makes the—

Ben Thompson

It coordinates—

Andrew Sharp

—the opportunities clear to everybody—

Ben Thompson

—the investments.

Andrew Sharp

Yeah.

Ben Thompson

You have all this stuff happening at the same time. And man, Byrne really nailed it with this insight. And we embrace the bubble, right?

Andrew Sharp

Mm-hmm.

Ben Thompson

This is why I don’t feel bad talking to James, asking, “Is it going to work out? Have I pushed him sufficiently on the tech, or should he share more?” Probably all this is true, but is this all going to blow up, where at some point we’re going to say, “Wow, we got a little crazy then”? Yes. Is the future going to depend on what emerges from the rubble that would never have emerged otherwise if that hadn’t happened? Also, almost certainly yes.

Andrew Sharp

Probably yes. Yeah.

Ben Thompson

And it’s really hard to write about and to analyze because as an analyst, you want to be sure. You want to have—

Andrew Sharp

Mm-hmm.

Ben Thompson

—clarity. You want to be able to follow logic.

And it’s kind of like—sorry, dude. I hope you’re doing your job listening in my very—

Andrew Sharp

I’m listening.

Ben Thompson

—high clarity—

Andrew Sharp

Don’t worry.

Ben Thompson

—as I’m rambling.

Andrew Sharp

I’m here.

Ben Thompson

I’ve just been thinking so much about this. It’s kind of like doing probabilistic computing on top of deterministic chips. It’s kind of weird and—

Andrew Sharp

Yeah.

Ben Thompson

—a little uncomfortable. There is a bit where I want to be a deterministic analyst who follows a logic chain: A to B to C to D to E.

Andrew Sharp

Mm-hmm.

Ben Thompson

I had the pleasure of doing that for the first decade of Stratechery. Actually, a lot of the job felt very easy because I felt I could see very clearly what was happening. I just needed to articulate it.

I could do a daily update about Microsoft earnings or Google earnings dropping and very clearly tie it to the dynamics of Aggregation Theory and all these sorts of pieces.

Andrew Sharp

Yeah.

Ben Thompson

Welcome to the nonlinear future, Ben.

Andrew Sharp

Here we are.

Ben Thompson

Yes. No, exactly.

Andrew Sharp

Who knows what direction it’ll go?

Ben Thompson

I feel like I’m trying to do deterministic analysis on top of probabilistic outcomes. We’re in a probabilistic world, not just in terms of AI, but in terms of the expected value of what’s going to happen.

Andrew Sharp

Mm-hmm.

Ben Thompson

Is James Proud going to figure this out? I don’t know. Is someone else—

Andrew Sharp

Yeah.

Ben Thompson

—going to recreate the chip fabrication process? I don’t know. Is it important and valuable that someone’s trying to do it? Absolutely. Would the funding and the desire to do it exist without the mania that we’re in? Probably not.

Andrew Sharp

Yeah.

Ben Thompson

That’s super important and valuable, and it’s—

Andrew Sharp

I mean, it’s unbelievable.

Ben Thompson

—pretty crazy to be a part of.

5. Chip Controls Force Innovation

Andrew Sharp

A premise of our chip conversations for the last 2½ years, specifically the Intel conversations, is that it’s just not economical for anybody in the US to try starting a foundry today. It would be insane. It’s not—

Ben Thompson

Yeah.

Andrew Sharp

—going to happen.

Ben Thompson

Yeah. It takes so long to move down the learning curve that, in the meantime, you’re going to go bankrupt 100 times over because China’s making chips. TSMC is making chips. You have old GlobalFoundries running; you can’t just jump to 2 nanometers. We talked about this with China, right?

Andrew Sharp

Mm-hmm.

Ben Thompson

They’re going to move down the curve because the chip controls give them a motivation to be super uneconomical. In a world without chip controls, nothing happens. TSMC just kind of rules the roost forever.

Andrew Sharp

On the leading edge.

Ben Thompson

Right.

Andrew Sharp

Yeah.

Ben Thompson

Right. And because, again, why would you buy from anywhere else? That’s why, number one, the chip controls are actually a big forcing function, and China probably is working on stuff like this as well. I’m sure they are looking at whatever—

Andrew Sharp

They’re working tirelessly.

Ben Thompson

—Substrate is looking at—

Andrew Sharp

Yeah.

Ben Thompson

—with a high degree of interest, to say the least. I’m like, “What’s your security situation like?” It better be very high.

Andrew Sharp

Yep.

Ben Thompson

But leaving aside the geopolitical points and the global competition aspects, the fact of the matter is we have way more investment going into this space than we would normally. In this case, it’s because of political considerations.

The point of the bubble is that, because of the mania, because there’s so much money at stake, and because everyone is pushing in the same direction, it’s also insane. I appreciated James Proud being like, “We’re an ideological company. We think the US should win.” And you look at that, it’s like—

Andrew Sharp

Mm-hmm.

Ben Thompson

“Could we have a technical reason why you’re going to win? Why this should be a thing?” But that doesn’t sound that much different from the AI companies thinking they’re inventing God.

Andrew Sharp

Yeah.

Ben Thompson

You guys are religious about this. And it’s like, yes, they’re religious about this. That’s why they’re spending crazy amounts of money with the belief that there’s going to be an AI takeoff. There is going to be AI that dominates the world. And you—

Andrew Sharp

Mm-hmm.

Ben Thompson

—need religious fervor to break through, to break out.

Andrew Sharp

To push forward.

Ben Thompson

Stratechery was easy for the first decade because the tech industry was in stasis, because we were just coalescing around these Big Five tech companies who were in their lane, did what they did, and it got a little boring, right?

I thought in 2020 and 2021, “When’s the end?” just because I don’t want to write about antitrust—

Andrew Sharp

What are we doing here?

Ben Thompson

—lawsuits for the rest of my life, right?

Andrew Sharp

Yeah, totally.

Ben Thompson

So I’m getting what I wanted, good and hard. It makes my job much more difficult. But it is—

Andrew Sharp

Your brain is melting on a weekly basis, but it is very, very exciting. Stasis is a good word for what the ecosystem can look like when you look around at trillion-dollar companies that are firmly entrenched, and then you remember that there’s always more to the story, and the future tends to be nonlinear and more complicated than one might expect.

Ben Thompson

Right. It’s precisely because TSMC is so dominant that you feel like a company like Substrate has a chance, just because you can see how TSMC is not going to respond to this. I’m sure they’re looking on with interest, and if they ever get asked about it, they’ll mumble something or whatever it might be.

Andrew Sharp

Mm-hmm.

Ben Thompson

There’s no way they can even explore or think about this. They’re so large, so pot-committed to the current thing that’s going on, and so dominant in the space that it actually makes it more viable for something completely new to come along because there’s not going to be a response.

Andrew Sharp

Yeah.

Ben Thompson

So, again, I’m not making any pronouncements on the viability, on how it’s going to happen, or on what’s going to work. I think it’s exciting that it’s happening, and all this stuff ties together.

Andrew Sharp

Right.

Ben Thompson

The big tech company spending, the cost of these machines, and these crazy moonshots—again, at a 1% expected return, that overall number, if it succeeds, has to be really, really large. And we’re getting to the point of those numbers being really, really large. All right, and that is the end of the free preview.
