The thing you should be more concerned about, if you ask me, is access to this breakthrough when it happens.

We live in a harsh unequal capitalist system not even slightly responsive to human need. It responds more readily to greed.

When it is discovered I expect the treatment to costs hundreds of millions of dollars. Why? Because people will still pay it and someone will get very rich.

Sad but probably true.

So all the worst people in the world will become immortal and everyone else will just die like normal.

I expect this will be the case for hundreds of years because those immortal few will ALSO use everything in their power to stop this treatment being socialised, knowing it will cause immense scarcity of resources as the population explodes. They will go so far as using police to violently suppress a rebellion.

I do expect this to eventually lead to a revolutionary scenario where humans demand life extension as a human right but many will die in the struggle and it probably won’t be won within our lifetimes judging by how hard fought anti capitalist struggle has been so far, without victory yet.

Sorry to be the bearer of bad news but it is the limits of politics and capitalism, that are the main threats to life extension for all of us but the very wealthiest few, not scientific discovery.

Arguably that’s harder to solve.
