Looks like there's a typo in the link for Urbit, should be https://urbit.org if anyone wants to take a look. Personally it seems like vaporware to me, there's not much based on the lofty promises of a new OS/language/social network.
Probably the only reason anyone has even heard of it is because it's the pet project of Curtis Yarvin aka Mencius Moldbug, known (somewhat infamously, a few of his talks at conferences have been pulled) for his association with the neo-reactionary political/philosophical movement.
