Unrelated to this good work directly, but I experienced a funny moment yesterday. My new employer issued me a 16 inch M1 Pro - naturally, I installed Rust :)

The thing cargo builds (in release, no less) about as fast as my previous machine could npm install on a particular project.

I realize this is all M1 just absolutely chewing through it, but as long as compiler time improvements remain steady and constant I don't think I'll have a ton to complain about.
