I assume you're not talking about solo work. For me, the quickest way to "flow state" has always started with human discussion. Only then does writing the code become a trivial task I can do alone. LLMs will never provide the flow because they do not set the goals. The tail does not wag the dog. They can only suggest implementation details.
Unless I'm working on totally unfamiliar problems, I don't want that advice for the majority of the code. Contrary to popular belief, there exist so many situations where there's exactly one right answer and countless wrong ones. There are less important miscellaneous parts I might have it fill in.
The only reason I cannot completely delegate to AI is because it cannot read my mind. Even then, it would probably still suggest crap since it is the averaging of those countless wrong answers. And still, even if it could overcome all that, I'm only saving a few hours at the end of several days of meetings.
I'm just not getting where the value is for anyone beyond entry level. I'm being totally honest when I say that I even stopped needing most search and documentation (for mature tools) over a decade ago. Back then, Stack Overflow was at its peak and I had the same questions about it. Offline coding is not only possible, but increasingly easier.
What am I doing different here?
