Ep. 031 - EMERGENCY EPISODE: Are We Doomed? | Jordan Nanos, Doug O'Laughlin, Max Kan, Joey Brookhart

“Pacing” would slow Anthropic’s capability progress without halting training or compute purchases, potentially weakening its strongest internal model.Near-term scarcity and safety workloads keep compute demand elevated, while semiconductor signals increasingly depend on frontier-lab ARR and capacity premiums.Bank hacks, data leaks, or AI-assisted biological attacks could accelerate regulation.
Ep. 020 - Anthropic vs OpenAI Usage, Margins, Meta Compute, Future of MSL (Tokenomics)
CrystalMax KanJoey BrookhartJordan Nanos
Anthropic’s enterprise/API mix is producing operating leverage: over 80% of ARR is API-based, Q2 operating profit was positive, and Q3 could exceed $1 billion.OpenAI’s free-user base weighs on margins, but 5.5 and 5.6 have reportedly restored a two-horse race, while subsidized coding plans and RL environments leave unit economics and capability scaling unresolved.
AI Chip & Silicon Round-up 2026

NVIDIA’s Vera Rubin VR200 targets 35 petaflops and 288 GB of HBM4, while AMD’s MI455X could gain a memory edge if delivered on time.Inference is increasingly shifting to custom silicon, with Trainium 3, Maia 200, and Ironwood offering credible alternatives; external access and execution remain key uncertainties.
