In I,Robot, Will Smith prefers to drive himself because he doesn't trust AI. But we are moving towards self driving as it would be more safer. Would you trust a calculation more if it was done by hand using log tables? Having vehicles allowed us to create sports like dirt bike riding or monster truck racing. Yes something is lost but something is also gained. We move up the layer of abstraction.

when i was younger, we didnt have cellphones. i had ~20-30 phone numbers memorized, at least. i also used to remember my credit card number. my brain has not deteriorated now that i have offloaded that to my phone.

point being: it depends on how you use it. if you offload critical thinking to ai, you will probably (slowly) atrophy your critical thinking muscles. if you offload some bullshit boilerplate or repetitive tasks or whatever, giving you more time overall to do the critical thinking part, you will be fine.

If your body is in good shape, stopping exercise won't make you deteriorate that quickly. What I wonder is, will people get in good shape in the first place.

What I mean is as someone with lots of experience, I don't care about me not learning about the basics anymore as much as someone in their 20s and 30s maybe should.

See the recent article suggesting use of navigation apps may correlate in populations to increased Alzheimer’s. Will it happen to you? Maybe, maybe not. Life’s a box of chocolates!
