This is like worrying about the sun going supernova after you've just discovered fire. Yes, eventually Earth will be reduced to a blackened cinder. And yes, if humans managed to live forever, there would be unforeseen (maybe bad) consequences.

If I get to live to 200, I still won't worry about it. If I get to live to 1,000, maybe I might start to think about it. Fortunately, by then, I will have had 1,000 years of experience to maybe come up with better answers than now.

Can you imagine the hubris of telling someone who has lived for 10,000 years that death is good because you can't think of what you'd do with that time?

Moreover no one is talking about making it impossible to die. No one is going to force you to live forever.

And that's the real problem for the nay-sayers. They know that they don't have to live forever if they don't want to. They just don't want other people to live forever. They want to live in a world where other people die.

This is all such complete nonsense that I don't know why we should confine our imaginations.

My goal is not just death but I want to die and be reborn as an Egyptian pharaoh.

Those damn fools who don't want to die and be reborn as whatever they want to be!

I'm in favor of improving longevity, but sometimes there is something to be said for other people dying. Imagine a world where Stalin was still alive and would remain so approximately forever.

I don't think this is a reason to avoid research on aging, but immortal dictators could certainly be a downside.

Had a chuckle at the mention of Stalin. Made me think. I would also think, the evils would be the one who would badly want to live forever, if an option was presented.

Queue the hot-mic moment between Putin and Xi where they discussed living longer with modern medical miracles.

[mrg3_2013]

That makes total sense now, indeed!

If one can make a good argument that people living forever would have too many downsides in the long run, one might reasonably not want others to live forever. This is similar to environmental policies. Even though one may not live through most downsides of current bad environmental policies, one may still want good environmental policies for the sake of their children.

Sure, I agree with that. But at that point it becomes a philosophical/ethical argument: should we allow certain people to die (or even kill them) to benefit others?

There was a time (not even that long ago) when 50% of kids died before the age of 5. I can totally imagine people saying back then that this was the "natural order of things" and that allowing every kid to live would be disastrous to the environment.

My philosophy is that we should allow (and even enable) people to live as long as they want. I wish that were not controversial, but here we are.

One could imagine this, but it wasn't a serious position that anyone actually held. I think discomfort with immortality, especially on consequentialist grounds, is a more legitimate concern

[GMoromisato]

This was famously the view of Social Darwinists. Herbert Spencer, for example, argued that nature should eliminate the weak. He said: "If they are not sufficiently complete to live, they die, and it is best they should die."

The most notorious case was probably Dr. Harry Haiselden, who refused surgery for some newborns with severe defects because letting them die was good for the species.

But, again, this is a philosophical/ethical argument. I believe that, in general, if people don't want to die, we should help them not die. I get that utilitarians are uncomfortable with that, but that's why I'm not a utilitarian.
