It may just be that this group of people isn't up to the challenge and, like you said, natural selection is necessary to produce a group that is up to the challenge.
Unfortunately that selection may come too late and much of the ecosystem may suffer for it.
Sounds a lot like giving up to me.
Wishing for human extinction makes you an enemy of all mankind btw
I'm saying that objectively maybe we should all die.
From a subjective perspective I'm going to keep fighting to the detriment of all the others around to the very bitter end and take down as many of them as I can, just like the real enemy of life that I am.
