Honestly, I think math education fulfills that job of code literacy to a great degree. It's good to understand how computers operate and be aware of code, but 'everybody must code' to me always has a subtext of 'I like coding, why don't you?' I personally don't like the endless reinvention of wheels, the omnipresent long variable names, and the widespread language fetishism of coding. I mean, all code runs on top of electronics but I don't think everyone should spend part of every day wielding a soldering iron and I doubt you do either. I think a lot of people prefer coding to electronic engineering because they don't care for burning themselves and sticking wires into their fingertips on a regular basis.
