Redox OS - an OS built entirely out of Rust
(www.redox-os.org)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sounds like python may be a better fit if its supported on the embedded devices you use as it will cover scripting and backend too. Rust has quite a learning curve and can be rather verbose.
I do use python quite a bit for scripting and backend, app, and I've used MicroPython a little bit, preferring C, C++ for embedded. It's pretty great for what I need.
I might mess around with Rust out of curiosity anyway, though the downsides you mention make it less compelling for me, personally. I'm not a big fan of verbose languages (e.g., Java, though I have used it for some apps).
Messing around with rust is certainly worth it, as it can change the way you think in a way that improves code in whatever language you write.
If you are curious definitely do check it out! It's a really cool language to learn and you'll start to enjoy the fight the compiler puts up.
I realize that even $2 systems are running full Linux distros these days but Python does not map to what I think of as “embedded”. If you have a full Python interpreter, it is already a pretty rich environment.
That said, this is what computing is starting to look like. There is less and less “bare metal”. I work with people that claim to be “firmware” engineers and then, when you look, you find out they have a full Ubuntu distro running and they may as well be running on a laptop.
Sorry but I don't see the reasoning backing the enthusiasm for python. Sure, it is great for scripting (this includes machine learning), but why for anything else?
An easy language that works everywhere? This person is writing code a few times a year.
