On the 80000 website itself, the list of problems it presents is so wildly disconnected from actual problems people rationally face every day it's hard to read. All the problems they present (AI, pandemics, whatever) is a hypothetical consequence of the capitalist system.

Start applying solutions to real problems people face. That's rational. Then notice how by removing the bad actors from the equation your scifi problems disappear too. That's rational. Telling the billions of people who suffer to shut up because AI extinction is the real problem and we need to throw money at it so that a hypothetical future might be better is just completely irrational, disrespectful, and anything but altruist or efficient.
