I am left wondering: When did coding become not part of the public education system? My father recounts learning how to program on punch cards when he was in school. In my day we learned BASIC in elementary school and Pascal in high school. I've talked with people who are several years younger than me and apparently they learned on different languages again, but were introduced to coding just the same. It certainly wasn't an intensive computer science education, but I'm not sure anyone is advocating for that anyway.
