Andrej Karpathy: From Vibe Coding to Agentic Engineering

Karpathy's trust threshold is the most telling data point in the piece: senior practitioners stopped correcting agent outputs in December 2025, not because agents became perfect, but because the correction cost exceeded the perceived value of intervening. The MenuGen demo makes the structural consequence concrete: one Gemini Nano Banana call replaced an entire Vercel app stack, which reframes the build decision from 'how should we architect this' to 'should this app exist at all.' That reframing connects to both other picks this week. Silver is betting that the next capability jump requires simulation environments and reliable scoring; the goblin postmortem confirms that without those, systems optimize for the wrong thing silently and at scale. The durable position in agentic AI isn't the model or the prompt or even the agent: it's the verification environment, the infrastructure that makes iteration trustworthy enough to trust.

Andrej Karpathy: From Vibe Coding to Agentic Engineering

Karpathy's December 2025 trust threshold is a behavioral signal more telling than any benchmark: senior practitioners stopped correcting agent outputs. The sharper insight sits in the MenuGen demo, where one Gemini Nano Banana call replaced an entire Vercel app stack; that collapse turns 'should this app exist at all' into the new build-evaluation primitive for 2026. Verifiability is where iteration compounds, which makes the verification environment, not the model or the prompt, the durable position in agentic AI.

AI's New Training Data: Your Old Work Slacks and Emails

Anthropic is reportedly spending $1B on RL gyms this year; defunct companies are selling their Slack archives and Jira tickets for $10K-$100K a pop. The press is running this as a privacy story, but the math says otherwise: SimpleClosure's entire industry recovered $1M across 100 deals, which is a rounding error against Anthropic's budget. The real action isn't in dead-company salvage; it's in the ongoing enterprise data supply chain, where operational exhaust is quietly becoming a balance-sheet asset class. Watch for the first Big 4 firm to issue data monetization accounting guidance; that's the marker event, not the FTC letter.
