I never would have guessed that Urbit has funding. That sounds like a very interesting job.
Do you have examples?
I'm on the record as having several severe criticisms of EY/MIRI, but being neoreactionaries is not one of them.
I'm referring more generally to the "Dark Enlightenment" than just neoreactionaries. In that group I include pretty much any group focused on alternatives to liberal democracy, with carve-outs for Marxists and fascists. EY fits comfortably into that category (see his "Politics Is The Mind-Killer" tract).
Whether this is what most other people mean with the terms you just used, is another point entirely.
I have no idea whether Urbit is as significant an idea as Mr. Moldbug suggests, but it's too interesting not to try out at least.
