It’s common for embedded systems to have some powerful cores running Linux and some microcontroller cores running real time code.

The fusion of the two is very valuable if you have applications that require real time work.

No, absolutely not. This is a very valuable structure for embedded work and it’s very common. I don’t know why you’d jump to such a cynical conclusion.
