Is rust like some sort of neoliberal intervention?

No it’s just the same annoying people that bandwagoned Golang back in the 2010’s now are bandwagoning Rust. There’s just a group of people that chase trends and are insufferable.

But what is the communist line on rust

Honestly I hope there isn’t one. It doesn’t really make sense to me to have a political stance weigh in on a programming language.
