Why do you think universities still give lectures, as the (contemporary) material has been available in written form for a few hundred years? Thousands of professionals, most of them smart and well-intentioned, have had these choices since the advent of cheap printing. Yet lectures today would be recognizable to the ancient Greeks. Why?
1. High quality video recording and transmission is still relatively new technology, and it seems most lectures are audio visual performances.
2. There hasn't been a push for a paradigm shift. Lectures work well enough, and have lots of benefits like creating a gathering of people. But does COVID change that?
