Indeed! It's also quite possible that some of the humans that will live forever (or until they choose not to) may already be around us.
And, rather sadly, if climate change happens as predicted it is going to make for a pretty bleak existence. It's one reason I'm fairly happy not to have had kids.
What do you think of Emil Cioran, btw? It may pique your interest.

If you shift a normal distribution to the right even a little bit, the frequency of tail events above a fixed threshold (in this case, wet bulb temperatures exceeding the human survivability limit of 35 degrees celcius) increases more than linearly.
This is especially an issue near the equator, which will lead to climate refugees seeking colder climates, north and south.
