I went to a top ten ranked cs school for what it's worth. I graduated pre-covid. Every single cs class has minimum 100 students. The department recorded classes so that they could increase attendance without getting bigger rooms. By the time I was an upperclassmen less than half the students showed up to lectures. Having 25/200 students present was common. It really was demoralizing to realize that the department didn't see a problem with many if not most students graduating without having actually spoken to a professor once, since you had to show up a couple hours early for office hours if you wanted to be seen. It's clear that the undergrads were nothing more than moneybags to my institution, so naturally students saw their education as the transaction it was. Most students were there because they figured graduating from a top school is what is required to get a FAANG job as a 21 year old.
