Personally, I wouldn't spend 80 years in school in one go. I would likely have taken a break to reset in the middle of my undergrad - and would certainly be in grad school now.

I'd imagine that many individuals will grow bored with their career after some number of decades and will switch. Starting at the bottom doesn't sound so bad if you can get to the top of the skill tree in 10-15 years out of 1000. It would practically be the same as spending a year on a transition today.

Society and human progress could likely stagnate.

So much of human progress depends on old, inflexible minds passing away to make room for new, young minds and ideas to take hold and evolve.

Can there be evolution without death and rebirth?

Divorce is common a thing, perhaps we'd move to something more like family pacts that last a decade or two... raise some kids then re-evaluate.

Maybe have a crypto-contract for that at 20 years you need to each pay a token to remain married else it's automatically disolved.

It's kind of cold, but so is living 1000 years I'd imagine. Though, I'd signup first thing just to see tech evolve.

Science risks being ground to a halt according to Planck's Principle[1].
