Have you ever heard of de’beers diamond hoarding story. Thats like what i expect would happen to humanity if we gained the ability to live forever, ‘manufactured scarcity’.

A tumultuous time of oligarchic rule with infighting to control the life extending technology. Eventually ending in a winner take all dictatorship. The masses would never see their lives extended (greener pastures visions may be made in the beginning). In fact common peoples lifespans would likely shorten as the controlling elite no longer required the same sort of widespread healthcare present even at todays standards, (depending upon where you live).

The elite would form a supplicant circle around the eventual dictator who maintains control, drip feeding the life extending technology to those who serve their dictatorship best.

Within a couple generations they won’t be a dictator but our Monarch, and the common people will obey, and descend to a miserable condition.

I may have let my imagination loose today a bit…
