It is great to solve "puzzle" problems and remove road blocks. In the past, whenever I got stuck, I often got frustrated and gave up. In so many cases AI hints to the corret solution and helps me continue. It's like a knowledgeable colleague that you can ask for help when you get stuck.
Another thing is auditing and code polishing. I asked Claude to polish a working, but still rough browser pluging, consisting of two simple Javascript files. It took ten iterations and a full day of highly intensive work to get the quality I wanted. I would say the result is good, but I could not do this process vey often without going insane. And I do not want to do this with a more complex project, yet.
So, yes, I am using it. For me it's a tool, knowledge resource, puzzle solver, code reviewer and source for inspiration. It's not a robot to write my code.
And never trust it blindly!
