Your answer confuses me. Background: I studied in Europe, from 2003 to 2010. Yes, professors had office hours, but you'd usually go there if something was extraordinary, or maybe if you really couldn't find a tutor or someone else to answer your pressing question before the test. We did have tutors, with weekly sessions, those were good for 90% of the stuff. Also it was recent enough that you could indeed write emails and expect an answer (CompSci though) But that's not the point, your "jump from student to student" confuses me - was this in a lecture hall with multiple people and some sort of panel Q&A? Office hours for us was basically waiting in line in front of the professor's office and going in one by one, also for the most part there were so many people that you'd hardly be remembered as an individual, so your "go talk to Sarah" sounds really unrealistic to me. But overall I am not disagreeing with you or the author a lot, my main point would more be: if their lecture was being streamed/recorded I probably would not have missed a single lesson, if I was in the position of the students here.
