Did you read the article? It's not just about replacing labour with AI but humans as a species to give birth to a machinistic god. The issue is that there is a quasi-religion forming around this ideology, and this are not just a few nutcases but people that are well-connected into industry and politics. Regardless of whether this plan is at all realistic, there is a not insignificant chance that these people will shape society and legislation.
My fan theory of Terminator: It was never the machines trying to kill humans. It was a handful of billionaires who controlled the machines attempting to kill all non-billionaires. They merely claimed they had no control.
Now I’m thinking that some of those billionaires may have worshipped the machines and convinced themselves that they were helpless. Miraculously, their own families were spared.
