I think the main reason might be that when the output is good the developer congratulates themselves, and when it's bad they make a post or comment about how bad AI is.
Then the people who congratulate the AI for helping get yelled at by the other category.
As long as the AI people stay in their lane and work on their own projects, they're not getting yelled at. This is ignoring that AI has enough proponents to have enough projects of significant size. And even if they're getting shouted at from across the fence, again, AI has enough proponents who would brave getting yelled at.
We'd still have more than tortured, isolated, one-offs. We should have at least one well-known codebase maintained through the power of Silicon Valley's top silicon-based minds.
