It makes me wonder whether everyone else is kidding themselves, or if I'm just holding it wrong.
I also use them for various coding tasks and they, together with agent frameworks, regularly do refactoring or small feature implementations in 1-2 minutes that would've taken me 10-20 minutes. They've probably increased my developer productivity by 2-3x overall, and by a lot more when I'm working with technology stacks that I'm not so familiar with or haven't worked with for a while. And I've been an engineer for almost 30 years.
So yea, I think you're just using them wrong.
It's also pretty useful for brainstorming : talking to AI helps you refine your thoughts. It probably won't give you any innovative idea, only a survey of mainstream ones, but it's a pretty good start for thinking about a problem.
