WSJ/Mims — 'Vibe Slop Crisis': 75% AI-generated code at Google, GitHub policy response, and the IPO-window verification arbitrage

Pichai says 75% of Google's new code is AI-generated, up from 50% six months ago; Claude Code's median user went from 20 minutes a day to 20 hours a week. GitHub changing its policies to fight AI-generated coding garbage in the same week the Zechner/Ronacher critique surfaces in WSJ isn't coincidence — it's practitioner alarm graduating to institutional press at exactly the OpenAI/Anthropic IPO moment. The market is pricing generation; the cliff it hasn't priced is verification.

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.
