He taught what plagiarism is, and how to transform it into a proper citation.
He explained his attendance policy, and very clearly defined WHY.
He taught why you shouldn't trust authority blindly.
He pointed out the problem with predestination, and provides instruction on how to earn an A in a fully remote manner later in the video
This is a well crafted lesson, aimed at adults who can handle a few fucking swear words, not children. It shows respect to their new status as grown ass people in the course of doing so.
It is a lesson in empathy, and if they don't understand it, they should ask their grandparents the next time they see them on zoom.
Brilliant stuff, worthy of a tenured professor. I hope he enjoys his now accelerated, well earned retirement.
