Interesting. Would you do it for animals too? It would suck to live for 400 years but your dog dies in only 10. How would people remember everything? How would you spend all that time? What would everyone do? Is this just for rich people or do poor people get to live for centuries too? Haven't done the math but if 8 billion people lived for say 500 years each, plus new arrivals constantly, wouldn't we accumulate rath…
"centuries" is far too short-term; "forever" is the goal, and "centuries" just buys enough time to get there. And of course that lifespan should be available to everyone. If the solution itself doesn't already imply a post-scarcity world, then it'll help that once you have a cure for aging, it's more economical to supply that to everyone than to treat the myriad complications that arise from aging. It's hard to get people to fund such a cure, but it seems far simpler to get funding for "we have a proven cure, let's get it to everyone".
> How would people remember everything?
In the short term, curing aging seems likely to help greatly with many degenerative mental disorders. In the long term, I expect people will find increasingly successful ways to augment their own capabilities. I doubt I'll have the same brain structure a hundred thousand years from now that I do today, if only because I expect we'll eventually run out of effective ways to debug biology in-place.
> How would you spend all that time? What would everyone do?
What wouldn't everyone do? I don't have a finite "bucket list"; my list contains everything positive I can possibly imagine, with a sort order applied, and it will always grow faster than it shrinks. Quite apart from the rest of the universe, other people provide an unbounded source of novelty.
Do you think people thousands of years ago would have asked such questions about a 120-year lifespan, and think it sounded too long?
If you lived for ten thousand years by default, would you think it too long and decide to die at 120? How about if you lived indefinitely?
