I agree with your general point here and I think it does a good job of addressing the really hyperbolic argument people have.

However i think you're focusing too much on one specific scenario to notice all the other really bad options. We as a species tend to revile the very idea of tolerating or being active evil but are generally alright with passive or apathetic evil. While active evil requires much rarer emotions like hatred or constant fear, passive evil is something that everyone participates in one time or the other and is extremely easy to take to great lengths just because it supports one's own convenience.

I think that while some kind of active genocide of the poor is very unlikely there is a genuine chance of the rich just not caring and letting "nature take its course" so to speak. Giving just enough to avoid some kind of mass violent movement as the average person slowly gets overtaken by hopelessness and depression. Another is the creation of entirely useless but highly demanding jobs to continue an undead version of today's economy just to keep people too tired to ask for more.

These options are all generalised, but my point is that there's a lot of extremely awful outcomes that do not require some kind of reverse Leninist "kill all the poor" stance.

Now, do i think that this is guaranteed or even likely? No. But the problem with discourse on this sub is that either side of the argument seems to consider it a strange binary and rarely ever admit any possibility but their own specific doom fantasy or regular fantasy.

I think extremely negative scenarios need to be discussed at length because we cannot afford them to occur, even if everyone thinks the chances are small. I'm all for discussing the positive effects of ai but there's a lot less benefit in my mind to discussing vaguely good scenarios rather than analysing the worst cases and possible ways to prevent them, no matter how likely one thinks they are to occur.

Doomerism is bad but extreme optimism is outright dangerous before we get to a good scenario.
