I dunno. It definitely can happen.

Code was never the bottleneck.

I've worked with plenty of teams that did the "in prod the same day" trick without AI.

The problem was just fucking ego. Designer has an ego, product owner has an ego, QA has an ego, stakeholder has an ego, platform teams have massive egos, developers have egos.

Unrelated but: the only reason people are shipping more with AI is because more people are ok with slop now.
