I think the people who like shipping quickly probably don't like building products in the first place and are looking for other aspects of entrepreneurship.

A huge benefit I find in AI is that it helps with a lot of things I hated. Merge conflicts, config files, breaking dependency updates... That leaves me more time to focus on the actual functionalities so I end up with better APIs, more detailed UIs, and more thorough tests. I do think it's possible to be relevant/competitive by only delegating parts of the work to AI and not the whole thing. Though it might change if AI gets too good.
