Like, after we drive ourselves off a cliff because of the natural world reacting to our bullshit, shrugging us off like insects, I'm dying to find out about the next epoch following the Anthropocene.
The next sentient species to roam the Earth, be it a million years from now....will they learn about us, will they enact communism? Will they actually live the lives that no species on this planet ever managed to live?
Shit, forget about the extinction of humanity. In the unlikely instance that civilization and humanity doesn't collapse, it hurts to know I won't be alive for a true communist utopia. Because it will come one day, it's inevitable. But it's sure as shit not happening within our lifetimes.
I can't say I'm much of a religious person anymore, but I also don't think there's any conclusive evidence that points to one thing or the other when it comes to what occurs after death.
Where you find nothingness uncomfortable (and how would you even perceive that once the lights are out?), others, even in this thread, find that thought to be comforting. There are still others that find the idea of an afterlife or reincarnation or whatever else that involves some form of living again to be uncomfortable, while another group of people find those thoughts comforting.
Whatever helps you mentally, it doesn't mean you need to give up any leftist values. There are plenty of people that have beliefs that are syncretic in this way.
