To any Nostriches who are curious about Urbit and interested in how what Vaporware is doing with Plunder is different, we started a blog and podcast and the first post is about those things:

https://blog.vaporware.network/2024/06/04/plunder-explained-for-urbit-users.html

A summary:

Plunder does not invent a new computing model, but instead recombines existing technologies in a new way.

In particular, Plunder is based on lambda calculus, supercombinators, and graph reduction.

Second, Plunder is explicitly political.

Plunder does not have a constitution and is not a republic, but it does encode a set of beliefs about the way human societies should relate to one another.

We believe the personal communications you have on the internet should be as private as the words you utter in your home.

Our goal is to make this viable for the first time.
