As someone who has worked on embedded systems for the past 30 years: It used to be a real big deal, but for the past 10-15 years it hasn't. We now have fully fledged multi core systems running everything. Even small embedded sensors or actuation controllers are 100+ MHz microcontrollers with oodles of flash and ram.

Now there has been an interesting turnaround with the whole chip shortage for the past years. All the young folk are at a loss, being used to just putting powerful chips all around willy-nilly. So they turn to the old folk like me to figure out designs with less chips, running busses all over and connecting dumb sensors/actuators to a central processing unit.
