I'm hoping that someone will one day build a RTOS in Rust that can run on M0 (or smaller) devices, comes with decent tooling (so you won't need projects like Platformio to compensate for the horrific tooling that embedded platforms have), and abstractions that are "just so".

The "just so"-bit is really hard.

Embedded systems need something like Rust.

I took a class in it at one of the RustConf's and that made me feel, even as a novice in the embedded space, that I would be able to do some great things. If I remember correctly the class was on an M0 board.
