I used to work in a space that was once considered to be embedded (POS systems, including some based on low-cost 8bit controllers, m86k based stuff and low-end ARM at the end), and got out of it just before the entire thing was taken over by fast 32bit or even 64bit ARM CPU's, which eventually moved to running stock Linux or Android. As ARM chips become cheaper and cheaper, the low-level embedded fields will shrink further and further, and the line will shift more and more towards running a full-blown OS below the actual applications. I've even encountered a platform marketed as being "realtime" which was running Linux.

It will always be there, micro-controllers are dirt dirt cheap, and in many cases more suited for industrial environments, and realtime will always be there, but it will become more & more specialized. And as you say, once you get down to a certain level the borrow-checker is a useful feature so I expect it won't be such an interesting target for Rust, and this will probably remain C's stronghold.

And even where Linux won't go, mbed os and it's ecosystem could take - as long as the requirements for faster time to market will continue.
