The Prototype-to-Production Gap Is AI's Dirty Secret

The top thread today was a direct challenge to vibe-coding optimism. The core claim: 'AI has dramatically accelerated the path to a first working version. It has not shortened the distance between a first working version and something production-grade.' Comments were split between engineers who've lived this and a smaller group calling the post defensive posturing from people worried about their jobs.

The fear that kept surfacing wasn't job loss exactly. It was value compression: AI raises the floor for everyone, so the signal that used to separate a good engineer from a mediocre one is getting harder to see. If a junior dev can generate a working prototype in hours, the differentiation shifts entirely to judgment, debugging, and production hardening, skills that are harder to measure and harder to hire for.

Counterpoint in the thread: some commenters think these 'prototype isn't the product' posts are a genre of cope, written by people who want to believe their skills are still scarce. The honest answer is probably both things are true at once.
