My current pattern is to manually craft during the first half of the day when I enjoy that, and during the second half when I'd be normally burnt on hard thought and not quite up for another coffee, pomodoro, theanine deep dive, I can start tackling tests, exploratory data analysis, or small bugs, and these tasks are 50% or more LLM.

So yeah, 30%-50% seems right, but it's not like I lost any part of my job that I love.

That's a good approach, I like it and probably adopt it as well. I'm not dogmatically against LLMs, I just need we should think about possible consequences, and not thinking about them like a holy grail of everything.
