Let me turn your question around, what are the benefits of communicating science via video such that it's a very popular medium that people use to learn about science?
Video also has communication modes that text/print lacks: dynamic graphics and empirical video (showing the thing itself happening), audio, speech and expression (as described above).
With all that, I find it quite frustrating to see it consume so much time that could be spent reading and processing several things. How do others on HN - intellectually curious and serious, often busy - reconcile that?
Though my question is really, am I missing things by not watching video - things I won't realistically get through print? I mean high-quality things - I want the equivelant of a paper, review paper, or book by a professional in the field.
