Verification — not execution — is the irreplaceable human job

Convergence

Three operators from completely separate lanes — agent frameworks, LLM evals, and AI research — published independently in the same week with the same core claim: the bottleneck of AI-native work is not intelligence, it is verification, and without feedback bound to every output, traces accumulate but systems don't actually learn. Karpathy from research, Chase from frameworks, Yan from evals. No coordination, same conclusion.

Implication

Audit any AI system in production for the verification + feedback path. Three diagnostic questions: (1) For each agent run, what's the feedback signal and where is it stored? (2) Can you produce, on demand, a list of runs that worked vs runs that didn't, with the diff between them? (3) When a prompt or tool gets "improved," is the change traceable to specific transcript-level evidence, or is it taste? If the answer to any is "we don't have that," the system is logging, not learning. The fix is not more traces — it's wiring feedback into the same store as the trace, then promoting patterns into config in a reviewable, reversible way.
