Rust lacunae

Amazon is investing heavily in Rust. For example, they are running production customer workloads on Firecracker VM that is written in Rust. And they have other products (both internal and external) in Rust.

I don't work in Amazon, but I've heard from my friends there that Rust in practice turns out to be a more productive language than C++ and much easier to pick up. One major advantage is that you don't have to learn the particular subset of C++ and its libraries that is in use in your new workplace.
