It comes from leftist roots in that Nick Land has (or at one point seemed to have; he's principally a shitposter so who knows) a roughly Marxist view of capitalism as a runaway optimization process only incidentally aligned with the interests of human capitalists. In the perfectly efficient world market towards which Marx thought we were heading, even the nominal owners are the "playthings of alien forces"; as profitability descends towards zero, firms that fail to maximize profit simply cease to exist. They disagree, of course, about what happens next. Marx thinks that this process is ultimately self-defeating, whereas Land thinks that you can actually just eliminate all human agency forever, and also for some reason is on board with that.
