  Fairness
   Only rich people will get it. (no tech has ever done this.)

Already, modern medicine expands lifetime and in particularly healthy lifetime significantly and the richer you are the more of it you can access.

Like, I don't have the same chances to get to 70 and still feel alright as someone born today in Bangladesh, or Zambia.

The world is already very unfair, and the only solution to that is to make it more fair, not to avoid developing treatments that, if the world was fair, would benfit everyone.

Specifically, make the treatments cheap and scalable, then ignore IP.

Then you will have no new treatments, and be back to square one.

Adapting a suggestion that I've heard and haven't studied too closely: Find insurance companies that essentially bet that people won't die in the next N years, find very large companies of this sort or form some kind of aggregation of them, and make the case to them that if they spend a bunch of money funding the development of some treatments that work, then they will make a profit because their bets will turn out better.

These companies exist, they sell a product called life insurance...

[waterhouse]

Yes, I was referring to that. I'm just not aware of such companies doing large-scale funding of life extension research to increase profits. I suspect it could be done, just that you might need to aggregate a lot of insurance companies to make it profitable.

[hueving]

Ah, but the other half of life insurance companies frequently sell annuities, which are bets you'll die soon enough. :)
