Counterpoints:
1. We don't have videos of The Gettysburg address. History existed before video.
2. There will never be another generation (in the near future) like boomers who didn't grow up tech savvy
3. Videos, like any form of documentation, are anecdotal evidence easily manipulated by what's "not in the frame"
4. The general problem you are describing comes from a faulty attribution of truth to video in our current day and age. The sooner we dismiss that the better
Yes, the transition will be awkward, but no need for hysteria.
