"Understanding debt": vibe coding fails the moment anything breaks
gerardsans · x · 2026-10-22
Gerard Sans argues that re-running the whole process to fix a failure means trading cost for understanding — and if that run fails too, you're back to square one because you never built the understanding needed to debug. The approach is fragile: any failure leaves you stuck.
He frames it as "understanding debt": vibe coders avoid failures for a while, until the debt becomes unsustainable and progress stops abruptly. He draws a parallel to recent AI-assisted math proofs — having results isn't the same as understanding them.
