I think this article may be outdated.

It was published in 2017. By 2019, the NYTimes was publishing articles like this, about the shortage of spaces in classes for people interested in CS: so popular students literally could't sign up.

Here's an article from 2023, about a 12x increase (!) in CS enrollments at UC Berkeley from 2011 to 2021. The trend at other unis was also strongly, like double-digit percentage increase yearly, up.

I think there was a brief cultural moment where for whatever reason - uncool? nerdy? math anxiety? - CS wasn't where you'd expect it to be, in terms of enrollment. But the culture changed & now it's very popular.
