Earlier quoted context omitted.
My friend’s father is a firmware engineer in Bulgaria and he hadn’t even heard of Rust. I’ve noticed that it takes a looong time for technologies to propagate globally
Is anyone expecting that most firmware engineers would already hear about Rust?
Depends, if I were writing low-level code like firmware or embedded systems, I would be casting envious eyes and dreaming of the day in 10 years when I'll get to start using it in production code. As a web dev, that's the way I used to view new APIs when I was still marching to the beat of someone else's supported browser list.
