Hmm. I use AI to write almost all my code, and I feel that the "part of the brain" I use is mostly the same. Pre-AI I spent a lot of time thinking about code architecture, schemas, APIs, etc. Post-AI I spend a lot of time thinking about essentially the exact same thing. Yea, there are some things that I used to think about that I don't now - the fiddly bits, like why my parentheses weren't balanced or what field I was missing that was causing a 3rd-party API to fail. But the work feels more similar than different.
