Humanity is almost definitely going to wipe itself out in the not too distant future through an avoidable (if not for the selfish greed of many of us) climate change resource war Great Filter event. This used to really bother me, but lately I'm thinking it is probably for the best.
One of my favorite questions to ask people is something like: "Imagine a button appears in front of you. Pressing it will snap all human beings painlessly out of existence. Do you push the button?" Some people get caught in minutiae about downstream effects, I tell them it can go however they want (house pets are free or gone too, planes land harmlessly, etc) In my circles, I've found it's about 50/50 button pushers…
My first serious programming job was at a start up and the owner asked me this question. I was caught off guard, of course I wouldn’t! I couldn’t really explain why at the time, but it essentially revolved around the fact that I was young and optimistic. 25 years later, I’m not so sure. Now, said optimism has almost vanished and there are days pushing seems like the path to least suffering, but I also feel it’s unethical for one person to decide for everyone else.
