Yeah, I have a mostly-functioning X11 server in Ruby, myself (not anywhere public yet).

Isene and I have relatively similar philosophies on this, except I have Claude burning tokens on optimizing and fixing my Ruby compiler now because I still want things in a high-level language, and my entire stack is Ruby instead of asm. But I love what he's doing - I just don't love x86 asm...

Turns out a functioning X server is a relatively simple piece of software. It's mostly just tedious. And most of the bulk is protocol handling that Claude can handle really trivially.
