It depends on how you use it. If I could afford a personal assistant I would have one and no one would tell me that's me not using my own brain. Using AI to help navigate a truly bureaucracy and admin heavy system is not not using my own brain. So maybe AI use can be evaluated on an individual level?
I haven't flown in nearly a decade now. I feel like I am able to do that. I don't need it for work or to see family and I travelled a bit in my youth. It doesn't mean I condemn all others who use air travel. Some people have to.
