REALLY?
We have not talked about this stuff for many years.

Good. That was the entire point of the story.

One might question why the movie industry keeps shooting 24 FPS, given what the
ITU is "discovering." To be fair, iMAX is typically a much higher frame rate.
Clearly, Cinematographers must be very careful about camera movement.
But the ITU is looking at video applications, including live sports. You could
see this coming for years; at least they are starting to consider the
requirements for a truly flexible electronic imaging system.
