Despite the marketing, the "I" in AI doesn't (yet) stand for "intelligence". You're best off finding applications where you can easily write a rigorous, well-defined, easily evaluated acceptance criterion and then let the model, harness, etc go wild. This of course is also the case with "AI coding" technology that came before--genetic programming, NEAT, etc. It's not intelligent, and therefore limited in fundamental ways. You have to steer it to make it work. This is very fundamentally different from how factory workers operate.

Therefore I can't see how the "software factories" concept is actually feasible without a technological breakthrough. We may be no closer to it now than we were 25yr ago.
