Over the last year, I noticed something about the way I work with AI.

I get much more done, but I also feel much more tired. Not “I need some coffee” tired. I mean completely mentally drained at the end of the workday, especially by the end of the week.

The strange part is that I am not working more hours. AI lets me do in one hour what could easily take half a day before.

That hour is just much more intense than it used to be.

A normal developer workday was never eight hours of nonstop hard thinking. You wrote code, read docs, waited for a build, got stuck on a problem, went for coffee, came back, talked to someone, tried something else.
