I think the point is that there's going to be an increasingly large percentage of the populace who think that the AI bosses / billionaire class did indeed do something against them.
But they didn't ask the rest of us if we're ok for them to murder someone on our behalf.
Personally I hope that AI will be a step change for the positive. I think it is inevitable that it will progress form here, in the darwinian sense, that someone else on this thread mentioned.
With that in mind, we should all be pushing for it to be used to our benefit, rather than detriment. And like almost all technological advances in the past, I think this can happen.
So if people are saying violence against Sam Altman is expected, then they're also saying violence against me is expected, because I am hopeful and vaguely supportive of the technology. That's quite scary.
Many tech billionaires openly, publicly and loudly said something among the lines: "I/we/my company/tech-bros are building torment nexus - it will take your job and/or kill people and/or shut up political opponents. You are powerless to stop this."
There are some of those billionaires willing to put their name and face in front of billions of people in the world. You will have no trouble finding people that will think that X or Y tech bro is personally responsible for some poor persons problems.
Especially when there's a bunch of news like "layoffs due to AI", "record investments due to AI", etc.
I am not supporting violence, never done it and never considered it. Though not surprising when talking heads of political/economical extremes can get threats from people that have nothing to lose.
People who shoot someone or throw bombs at someone even though that someone never did something against them, should be marginalized. In prison.
