I find that any additional overhead caused by the separate AI chat is saved 20x over by basically never having to use a browser to look at documentation and S/O while coding.
That makes sense. I do use AI for questions like "what's the best way to flatten a list of lists in Python" or "what is the interface for this library function". I just don't use it the way I see some people do where they have it write the rough draft of their code or identify where a bug is.
