I'm old enough to just barely remember frantic screaming about VHS video cassette lectures would destroy academia. 20 years later academia was still around so I could pay lots of money to attend, but a decade or to ago VHS cassette tapes mostly disappeared.

It is rather reminiscent of claims the VCR would destroy Hollywood back in the 70s/80s. Complete with the (hidden?) assumption that the existing business model is worth saving, that useless jobs must be saved at any cost, anti-technological progress rants...
