For me AI mostly reduces time effort. AI types code faster than I do, looks up stuff on the internet faster than I do, debugs faster than I do, but doing those never required much "brain effort" from me.
What does require "brain effort" from me is making educated decisions. Mostly during planning to figure out which pros/cons of each possible approach are actually relevant for our situation - AI does this poorly, makes lots of wrong assumptions if you don't steer it correctly, and noticing these + correcting AI on them requires "brain effort" too. Then the part of code review where you think about what can go wrong. AI still sucks at figuring out edge cases. It doesn't "know" the entire codebase like I do, its context only has "the parts of codebase deemed relevant".
Before AI I could jump from 30 minutes of hard thinking into an hour of coding during which my brain essentially rested, before returning to hard thinking again. Nowadays those hour-long coding sessions turn into 5-10 minutes of watching AI do something.
So for me using AI doesn't "free up brain juice", it instead makes me use my "brain effort" more, and in a workplace environment gives me less time to rest and makes me more tired, cause nowadays bosses expect us to work faster + colleagues working faster means more review requests.
