Counterpoint: in the space/aerospace world, having embedded systems running tens of millions of lines of code is common. These have many large software teams working together. Most software engineers on these embedded programs are just that: software engineers. I've worked in embedded for a long time and have never "physically" debugged or otherwise physically touched the hardware I work on. There's a lot to embedded systems outside of microcontrollers.
