And yet, lots of people still do

Yes, but they do them because all those famous basketball people are distant and unreachable. Which allows them to still be competitive in their own local neighborhood. What if Michael Jordan, Chamberlain, Bryant and James are your neighbors? You will always lose the game, always perform worse than them and there is zero hope to even get anywhere near their level of performance.

The whole motivation to do a task takes a dive when you know you will fail and never get to a level where you get acceptable results. And yes, basketball might not be the best example here, but painting, writing, music, programming? What motivation have I left to write my own story when AI can write my own stories better and faster than me?

We already see the start of that today on Twitch, where artists draw something live on stream and than somebody comes in, takes a screenshot and finishes it before they do. That's going to be the new normal and there will be generations growing up with that level of technology.

Or look at all the kids that no longer go outside to play in the mud, but stay home to play video games. Having tech around changes our behavior.
