This polemic identifies CS as the culprit. That seems empirically wrong. As stated, it's "not a prerequisite for most programming" even in theory, and in practice, there are mountains of GitHub programmers, at least, who don't have CS backgrounds. Non-CS folks probably account for most of the "frontend"/"full stack" development today. This has exacerbated the Tower of Babel, not improved it.

HCI is CS—and that's what we should focus on. There's a fair bit of emphasis on engineering due, too. To be able to look at a problem and ask, "What should it take?" and ocnversely, "What isn't required here (contra cultural imperatives)?"
