Today physical world is largely mechanized, we rarely walk, run lift heavy things for survival. So we grow fat and weak unless we exercise. Tomorrow vast majority of us will never think, create, investigate for earning a living. So we will get dumb and dumber over time. A small minority of us will keep polishing their intellect but will never be smarter than machines just like the best athletes of today can't outrun machines.
This is surprisingly a great analogy because millions of people still run every week for their own benefit (physical and mental health, social connection, etc).
I wonder if mental exercises will move to the same category? Not necessarily a way to earn money, but something everybody does as a way of flourishing as a human.
I don't know... There are plenty of otherwise capable adults who just get home from work and watch TV. They either never, or extremely rarely, indulge in hobbies, go see a concert, or even go out to meet others. Not that TV can't be art and challenge us but lets be honest, 99% of it is not that.
