@caseynewton@zoeschiffer My physics professor taught us to watch for words like "obviously follows" and "of course." He said this is how a lecturer elides the part of the proof they don't understand.
Up to this point, I was wondering why you didn't find anyone from Facebook to talk to—even though FB, much more than Amazon, Apple, and Google, was roiled by employee dissent in 2020, and before that in 2018 in the wake of the Cambridge Analytica scandal and the Kavanaugh hearings. Now I see why.
