I know others are piling on but there is also adoption at Google, Facebook, Fastly, Dropbox, Yelp, Reddit, 1password, Discord etc. The list goes on and on. I know more that are using it heavily but aren't public with it. I've spend the last 8 years of my life (minus a short one year stint with python) writing Rust in production. It isn't just hobbyists and hasn't been there way for a long time.
