It does puzzle me that most reactions to these problems are not "let's solve them", it is "I want people to die".
But the vast majority of people in my experience instantly reject it citing some possible problem that might arise, and no further discussion can usually be had with them.
I've come to believe that the subject of mortality just triggers a huge irrational reaction in most people. They don't want to think about it at all.
I don't think it is realistic, if for whatever reason it does happen I think we are not ready for it. That's all there is to it.
I am saying that in my experience, most people do not want to discuss it at all. They will bring up some obvious possible problem that might be caused by it, and then refuse any further discussion.
I think (but don't know) that this is an irrational reaction to the topic of mortality.
Sarcasm and condescension do nothing to drive the conversation forward and really just mask your own ignorance to solving the problem as well. If a solution already existed to the degree that it was common knowledge in public forums then I guess there wouldn’t be a problem would there?
The fact that massive divisions of companies like Alphabet (Calico) are dedicated to solving these problems seems to indicate that not all of us are deathists satisfied to recuse ourselves to mortality on the basis of some flimsy naturalistic fallacy.

Given the degree to which industrialization has gotten us in trouble they may well have had a point. Good luck re-designing all your cities for non-motorized transport once that luxury becomes unaffordable.
Billionaires trying to extend their life-spans is as old as the Pharaos, 'deathists' is a great way to spell 'realist'. You too will die, get used to it and make your peace with it lest you die frustrated and old.
Oh, and don't forget to give your fortune to de Grey, after all, if he can't nobody can, better to have him succeed and then allow you access to life eternal. In fact, everybody should give all their money to de Grey, that will all but guarantee success.
This is how you spell immortality: cancer. The one thing that keeps us in check right now is death. Without that safeguard there would be very little standing between us and eventual total collapse. Right now we still have a chance.
