I suspect, rather strongly, that what really specifically wears programmers down is boilerplate.
AI is addressing that problem extremely well, but by putting up with it rather than actually solving it.
I don't want the boilerplate to be necessary in the first place.
Or, for me, yak shaving. I start a project with enthusiasm and then 8 hours later I'm debugging an nginx config file or something rather than working on the core project. AI gets a lot of that out of the way if you let it, and you can at least let it grind on that stuff while you think about other things.
