Not watched the video, but hate to tell you, they are designed by visual thinkers. Linearization comes after the fact; one has to be able to visualize the operation of the logic networks etc during the design - and debug - processes. Things happen in parallel a lot inside a computer, no way is linear thinking going to create that. Validate, yes, but not create.

At least, that's my experience, not just of myself but of a number of the early inventors of these things that I happen to bump into a few times a year. Those still surviving that is.
