> AI promises a feudalist future where there is no capital that isn't owned by the ruling class.

We may get that, but only if the ruling class want what the Victorians called a "folly": https://en.wikipedia.org/wiki/Folly

AI is wildly, wildly divergent in the possible futures it brings. It's really important to influence what happens, but don't limit the potential downside to only as bad as feudalism (neither neo-feudalist nor re-enacted): much worse monsters exist than the typical feudal lord.

(Was going to say "among those rulers who needed us alive to fight their wars and grow their food", but then I remembered Cambodia and Pol Pot).
