There’s quite a bit outside of the urban and tech. The corpos have been extracting value instead of creating it for centuries without needing computers to do so. I’ve gotta say that I also don’t necessarily buy it as a thing, seems like another incarnation of dickensian conditions under capitalism.
That’s not to say that I don’t think that there are some ultra wealthy that are pushing for a neo-feudalism, like the Kochs or the fellow who killed Gawker but I think that “technofeudalism” is a poor description for their aims as advanced tech isn’t necessarily involved.
