C is still by far the most dominant: even convincing embedded developers to use C++ can be a challenge. A subset of the rust community is focusing on it for embedded work, and it's very interesting for that in a few ways (relatively little technical reasons not to use it now: basically if it's an architecture LLVM can target you can write rust for it), but it's basically not even on the radar of most firmware designers (who as a group are fairly conservative and not likely to be looking for new languages anyway).
