Braindead bourgeois horseshit from a venture capitalist without any social or philosophical foundation. It's not even a book, just a bunch of half-formed drivel.
Fundamentally, the problem is that he believes that capital is _real_, that it is a tangible "thing" which humanity has now produced enough of, and not a _measurement_ of how authority flows. The fact that people in Flint don't still don't have access to clean water is a perfect example of this, which he brings up, though bizarrely to support his moronic idea that there is enough capital already, so then maybe we can keep our social structures the same but feel good about it by giving some small pittance to the trampled masses at the bottom.
