You are correct: I think the definition has been fixed in time even as the underlying meaning changed: I've programmed "embedded systems" that were based on x64-class processors.

But that's not the important part. I think one major problem is that the term "embedded" puts a lot of engineers into a frame of mind that rejects programming in anything high-level. We have done lots of projects where something like MicroPython would have been perfect, but every time I try to sell something like that, I get a bunch of excuses that really aren't grounded in any concrete objection and we go right back to twiddling bits in C.

Usually that is the same crowd that even refuses C99, or any other compiled language in alternative to C, even though there are vendors still in business selling such compilers.
