People commonly refer to any task that involves programming as computer science. While there may be some similarities, this is like referring to building IKEA furniture as carpentry. They use the same medium, but require vastly different levels of mastery. To me, it's disparaging to ask a professional carpenter to teach people how to construct prefab furniture. And in the same way, it's inappropriate to ask a computer science professor or software engineer to teach people to write basic HTML.
It's a mistake to assume most people need to understand computer science. But to be digitally literate, people do need some basic programming skills. This is similar to how people should know how to use a screwdriver to construct furniture even if they couldn't design the furniture themselves. Someone should offer workshops to teach people this practical IKEA-level of programming.
