I am sorry if at this point is kind of an interruption of your conversation, but I believe I disagree only with a little detail my fellow human said, and I think it is important. There is a way to be a "doomer" or whatever name we get nowadays without believing in a trajectory. I do not believe we have a fixed path. I believe there are a lot of options, but all within a range of possibilities (we won't develop wings tomorrow and sparkle and be angels all of a sudden). And the thing is I believe that realm of possibilities is mostly negative from our point of view. That many possible paths are okay, even some kind of good, but many many others are bad or frankly terrible. So, in that way, I believe I am a "doomer" without thinking that it will all go downhill. No, sometimes history gets a good chapter, a good period of time, here and there; still, overall, I'd argue existence is mostly or predominantly negative/ugly/sad/not-likable.

And I agree with my fellow lemming that the only thing left when you view things like this is to try to make things better, thus, "doomerism" shouldn't be apathy or defeat or whatever, it is a very urgent call to reduce the suffering we 'diagnose' and to make the world a better place.

I wouldn't call it "doomerism", I'd call it philosophical pessimism (because it's more technical and Wikipediable, lol).
