That's 60 companies. Granted there's bound to be a few more but calling it "pretty mainstream" based on that seems like a stretch to me. Though not a flawless datapoint I'd rather use something like the TIOBE[1] index, which puts Rust at 0,37% rating, or position 41, right below Erlang. I hope that'll change, I think Rust has some interesting concepts and could be a notable step forward for some things that we've always done in C. But I can't find a datapoint that would make out Rust as being mainstream today. [1]: https://www.tiobe.com/tiobe-index/ https://www.tiobe.com/tiobe-index/
