Both are useful! They're not mutually exclusive!
But thanks to technology you no longer need to lift heavy things to survive or live a good life.
So shall it become for the mind. All the banal, unpleasant "cognitive labor" people perform now - copywriting, TPS reports, documentation.. that's all gonna get automated.
You used to need to be strong to wield a sword and shield while wearing armor and go into battle and try to not die defending your city or country. Now thanks to a great heaving pile of innovation and quality of life improvements we've won over centuries, we can decide one day to compete in bodybuilding. Same muscle gains, less danger, way more fun. All the country defending is happening elsewhere. Maybe the same will happen for our minds.
Imagine a future of brain leisure - one where we can go compete in bodybuilding competitions for the mind! Perhaps, a live stream where people do cool brain things. Who would line up to compete to compose the most engaging poem - on the spot, no assistance - in some obscure language from a continent they weren't born on. How cool would that be to watch!
Uh oh.
Oh dear. Oops. Sorry team. I forgot we were doing the doom and gloom thing, only looking 1cm from our noses and seeing disaster.
