The number one use case for AI for me as a programmer is still help finding functions which are named something I didn't expect as I'm learning a new language/framework/library.
Doing the actual thinking is generally not the part I need too much help with. Though it can replace googling info in domains I'm less familiar with. The thing is, I don't trust the results as much and end up needing to verify it anyways. If anything AI has made this harder, since I feel searching the web for authoritative, expert information has become harder as of late.
