These are some of the best explanatory presentations in existence. I would love to see them analyzed to better understand how they are so effective.

Eliminate jargon, simplify as much as possible... but no more. You can explain almost anything to anyone, if you recursively apply this technique.

The secret is in the spline! Also: this is not how modern power steering systems work.

Yes, most hydraulic systems today have been replaced by electric power steering, which uses electronic sensors to determine how much assist to apply via an electric motor. Mechanically, it is simple and very low maintenance.

More like "hydraulic power-assist steering" in modern terms.

With modern "hydraulic steering" it tends to imply no mechanical coupling between the steering wheel and the movement of the wheels/rudder/motor. A hydraulic leak or pressure failure therefore causes catastrophic loss of steering.

Well, even before electric power steering became popular, rack and pinion steering was/is used in almost all passenger vehicles. The only vehicles that I can think of that use a steering gear and pitman arm like this video are 1 ton Ford/Chevy/Dodge and the Jeep Wrangler.

It's very 1950s military.

They never mention that this is a simple feedback control system. The mechanics that maintained the thing had to know that, since it's vulnerable to the oscillation and lag problems of a simple proportional control system. Those feel like steering wheel vibration and slop to the driver. This is for an off-road heavy truck, not a sports car, so a little lag is not so bad.

The very large vehicle at the end is the M65 Atomic Cannon.

>simplify as much as possible... but no more

Is an excellent lemma. Applying it, of course, is what's very difficult :)
