MMOs are kinda costly to run, but as it turns out, nowhere near as costly as a datacenter. I was going to spend most of this article joking about how Sam Altman, who doesn't like that we have RAM, would be frothing at the mouth for that kind of compute power. After a bit of research I am leaving horrified at the sheer industrial heft the AI industry requires.
