It’s not indifference and I find the people saying ‘Oh well humans are awful we might as well die’ are either trolls or sociopaths. This is Mumsnet, most people have children, for posters saying the stuff above, do you get a kick out of it?
No, I'm just totally ambivalent about the future of the human race. As individuals none of us are immortal, so we all die at some point, and as a species it's also inevitable something is going to wipe us out, likely before our Sun implodes and takes us out anyway.
Do you find the idea of your children, your friends children, your grandchildren, all dying amusing do you?
"Amusing"?
No. I'm just a pragmatist, so I'm not going to waste time and energy worrying about something which is an inevitability and I can do nothing to prevent in any case.
Again, all human beings are mortal, so all of those people are going to die at some point, I don't have children or grandchildren so that's not a concern for me.
