I actually asked Ron Minsky about exactly this question on Twitter[0]: Me: [W]hy not just use Rust for latency sensitive apps/where it may make sense? Is JS using any Rust? Minsky: Rust is great, but we get a lot of value out of having the bulk of our code in a single language. We can share types, tools, libraries, idioms, and it makes it easier for folk to move from project to project. And we're well on our way to getting the most important advantages that Rust brings to the table in OCaml in a cleanly integrated, pay as you go way, which seems to us like a better outcome. There are also some things that we specifically don't love about Rust: the compile times are long, folk who know more about it than I do are pretty sad about how async/await works, the type discipline is quite complicated, etc. But mostly, it's about wanting to have one wider-spectrum language at our disposal.
