The decisions that look free today can become expensive in six months – and AI accelerates the process at exactly the moment when the bill is quietly written. This talk is about that trade-off. The friction that vibe coding removes used to be where feasibility and constraints were discussed, so implicit decisions are made by the model instead.In this talk, Alex Ponomarev covers where “free now” turns into “costly later”: blurred guardrails, code shipped without understanding its structure, and verification deferred. He shows how to price that deferred bill up front – by choosing which decisions to log and which to keep reversible. AI does not eliminate technical debt. It issues it faster and bills it on a delay.
