I have no idea what prompts questions like these.

We got to 80 without inventing money. Living that long back then was hard work every day.

Then the industrial revolution happened, and we got state pensions at one end of life and extended childhood a few years past adolescence on the other. We currently pay for this… by taxes funding both education and a pension.

Absent the radical transformations of an AI driven economy, we live 200 years in exactly the same way.

With those transformations, all bets are off unless they violate the laws of physics.
