Even if AI were superhuman at all thinking tasks, that doesn't mean we'd lose our abilities.

Chess and games can be a lot more demanding than a lot of people's work lives - and AI is already superhuman there.

The heaviest thing I need to lift in my daily life is a laptop and yet I've gotten significantly stronger over the last few years from strength training.

If AI took over all the boring but hard things I'm required to do it'd free up lots of time for me to spend thinking about things, and solve problems I find more interesting.
