For coders/devs --> AI is useful only to novice coders ai give them a basuc core/template code to start with that they can modify

But actual coders who work in companies on projects thay have to follow different styles/languages/algorithm for coding practices, ai cant conform to that , if you are working on legacy codes or refactoring you need to maintain the style and format the code already is in, ai cant give you exact, you cant say ai these is my million line, code scattered on thousand files, analyse and add these feature while maintaining sanctity of current code practice

Ai will just introduce new bugs and you will waste more time in finding and solving

AI gives productivity boost only if you are starting from scratch, it can give you core code / boilerplate to rapidly start with adding features
