this is awesome! it fits well with a lot of the (mental) notes I made tracing Urbit history as part of a deconstruction of the earlier inroads technofascism made into the wider tech world. some loose notes to expand on a couple topics:

• very little of Urbit is actually original. the language itself (called hoon if I remember correctly) is a lambda-calculus-heavy ML with a Lisp-style type system and runtime, with all the names changed to blur the line between Yarvin’s bad ideas and the ideas from computer science that Yarvin implemented poorly
• notably, hoon inherits the computational inefficiency of lambda calculus but none of the safety of ML or the usability of Lisp. the resulting language is an awful cacophony
• these sources were most likely used not because Yarvin is any good at functional programming, but because Urbit was a partially successful attempt to insert yarvin’s ideas into the conversation on places like hacker news, where paul graham primed a bunch of folks to accept both Lisp and right-wing libertarianism as the same bundle of ideas
• the few unique parts of Urbit are interesting only in that they seem to be early attempts at things we’ve seen done by other techfash projects. for example, Urbit claims to be decentralized, but hoon programs are permanently linked to code controlled by the Urbit foundation (most likely still owned by Yarvin even though they claim otherwise), which compliant Urbit implementations must pull from the network (also controlled by the foundation). this allows programs to be effectively broken on the whim of whoever controls their access to their upstream dependencies, effectively making whoever controls the foundational Urbit libraries the rulers of Urbit’s neo-feudal network — and it’s built so that swapping out those dependencies is as hard as possible. I haven’t checked the implementation to see if it prevents changing the meaning of downstream programs yet (because hoon code is brain rot — see the example linked above)
• I need to dig through Reddit and find the AMA, but yarvin claims that Urbit is the first and only functional language that can pull functions and dependencies from the network. this is false and he probably knows it — Eelco Dolstra’s foundational paper on the Nix package manager was published (this is from memory, probably not accurate) about a year and a half before Yarvin’s first blog post on Urbit, and there are enough similarities between the two that I don’t know if I want to call this a coincidence

last time I brought this up on r/SneerClub, some weird fascist found the post and made the mistake of linking Yarvin’s original blog posts, which are kind of hilarious. I’ll dig them up and link them here when I can
