"You can't search lectures you attend in person either, yet that format has endured for quite some time."

There weren't really an alternative, so whether the format has endured or not isn't really relevant. Many other schools are doing this differently. At this point your statement about "holding back the progress of an entire society" seems rather hollow. I can't convince you data exposing data is more useful, but I also shouldn't have to. It's one of the fundamentals of computer systems if not the Internet.
