Android has a lot of Rust now (the bluetooth stack was rewritten in Rust), npm is being rewritten in Rust, Servo is written in Rust, Dropbox' sync engine, Amazon AWS Firecracker, Discord is replacing Go with Rust, Google's new OS Fuchsia has a lot of Rustl. There are also tons of companies looking for hire Rust programmers, e.g. Apple, Intel, Microsoft... there is work to allow for development of drivers in Rust in the Linux kernel.
Compare this to Haskell. Where is it being used? What is it replacing?
