All the EEs I know think 1000 lines of code is "a lot". I've never met any EEs that used source control. I've never met any that tracked issues beyond forwarding emails back and forth. Their idea of documentation is separate PDFs for electrical properties and programming APIs.

So if us software engineers don't know the hardware side well enough to design hardware, I'm not really sure electrical engineers understand the software side well enough to design hardware, either.

Not saying there aren't EEs that understand software. Just saying I've never met any.

EDIT: wait, I know one EE who uses source control. I finally got my wife to start using Git. She kept looking over my shoulder at home, asking me "what is that?" pointing at my changelog in SourceTree. "Oh, you know, it's just an annotated record of every change every member of the project has ever made, including when they did it, in such a way that we can share these changes with each other without having to have long discussions about which particular folder on which particular network drive is the 'latest' code. Oh, you think that would be helpful in your work? Who would have thought?"
