Urbit is also written in PHP. A clone of Urbit is written in Rust, i was reading it's source some years back, i don't even remember it's name, but i had this feeling of "Ok, what is that thing doing".
But one thing is clear to me. Blockchain technology + IPv6 opens a lot of possibilities to re-imagine networking, and that's what Urbit is mainly focused on: networking.
A good blockchain technology also has possibilities to re-imagine parts of OS.
For example we will not need to have local users if all identities can be verified using credentials stored online, immutable forever. Also we won't need to have local networks, DNS, Time servers etc. Everything will be global.
Many ideas there, but each one of those problems is unbelievably hard by itself, all of them together is half of the internet and computing infrastructure.
