No. It's not more AI. The solution is designing and sticking to development process that is more resilient to errors than the one that's currently happening. This isn't a novel idea. Code reviews weren't always part of the process, neither was VCS, nor bug tracker etc.

The way AI is set up today, it's trying to replicate the (hopefully) good existing practices. Possibly faster. The real change comes from inventing better practices (something AI isn't capable of, at least not the kind of AI that's being sold to the programmers today).
