I feel tired working with AI much faster than I did when I used to code, dunno if it's just that I don't really need to think much at all other than keep in mind the broad plan and have an eye out if a red flag of the wrong direction shows in the transcript, don't even bother reading the code anymore since Opus 4.5 I haven't felt the need to.

Manually coding engaged my brain much more and somehow was less exhausting, kinda feels like getting out of bed and doing something vs lazing around and ending up feel more tired despite having to do less.
