It may be superfluous in this forum, but one should note that the video's
characterization of Brian Kernighan as the father of typesetting at Bell
Labs does great disservice to Joe Ossanna, who single-handedly
brought the first phototypesetter to the labs, subjected it to computer
control, and wrote troff (which lives on 50 years later) to drive it.

In  passing, the video denigrates the C/A/T because it had a fixed font
repertoire and no general graphic capability. But without the antecedent
of C/A/T and troff, the famous Linotron summer-vacation project would
never have been undertaken.
