I agree the free money in like one month coded SaaS apps are in big trouble. But like there's no way I'm gonna have the vision to desire to play a game I made myself using AI for instance (just the fact that I prompted it into existence ruins some of the exploration of a game made by someone else). So at the low end of the extreme (easy to make SaaS apps with basic code and a db) AI is a thread, but at the other end of the extreme (requiring vision and where human attention is a bottleneck) there's definitely still tons of opportunity.
I think a lot of people will do this, it remains to be seen how the actual economics of this shake out in the long run, especially considering, it’s not like the existing vendors are going to remain static.
