The "Epstein class" of multi-billionaires don't need AI at all. They hire hundreds of willing human grifters and make them low-millionaires by spewing media that enables exploitation and wealth extraction, and passing laws that makes them effectively outside the reach of the law.
They buy out newspapers and public forums like Washington Post, Twitter, Fox News, the GOP, CBS etc. to make them megaphones for their own priorities, and shape public opinion to their will. AI is probably a lot less effective than whats been happening for decades already
