How do you image the world will work if everyone is living on "compound interest".

The economy is imploding because a tiny fraction of population is living on "compound interest" even now.

I reckon this would be self-correcting. If the average person could reach retirement in such a small fraction of their lifespan, then the vast majority of the population at any given time would be non-productive retirees. The economy would slow until your interest was zero and you'd be forced back to work. Eventually an equilibrium would be reached, wherein the average Joe could look forward to a rewarding and fulfilling career of, say, 450 years or so.

> Why? If you can live 500 years just focus 20 years on compound interest hard, then retire for 400 years?

The first version of this technology will only be available to billionaires. So if you reach 70 when it’s invented and are not a billionaire, you’ll never get to try the 500 years of compounding trick

We’re likely to see this stuff get invented in our lifetimes (I’m 38), maybe practical, but we’re def all too old to see it become widely available.

Then again, life extension will not be a singular technology. You could argue antibiotics and vaccines were the first big step and those became affordable within a few decades of invention

If you're late on the monthly payment, they send a guy to repo the life extension.
