As a senior dev I have found AI useful for auto completion (where you see beforehand what it wants to write directly in Visual Studio) and code analysis (as it does find some bugs and can give good hints for code structure). I would never trust it with anything even remotely complex though.
It kinda scares me that people trust it enough for "agent mode", as giving it direct access to change stuff directly has simply put never worked.
You do refactoring with auto complete?
