At least where I am we can’t and shouldn’t know all the requirements of a project beforehand^. Every project is an iterative learning process between the users, product and engineers. The problem is if everyone uses AI to replace their thinking it breaks that process and no one learns anything.

^ I say shouldn’t because I work in research engineering. Most of the needs of our users are pretty unique. We’ve had people come in and try and specify every piece of work, -and ended up building a crud app no one wanted or used.
