In the narration he mentions that a 24 speed gear set, or even more,
would be perfectly feasible. No wires, no cables, either.

Just a rehash of old ideas. The same reasons for the failure of shaft
drives will see it fail again. Of couses, as ther is electronics
involved, that will introduce another pile of reasons for it to fail.

Why did shaft drives fail?
Solp and flex were one. Road crap is another. Hard to maintain.
I can not wait to see that drive train after a days mtn biking on wet,
rainy days.

Complexities? And so we have hydraulic brake
systems as opposed to simply mechanical brakes, electronic shifters as
opposed to simple mechanical systems, and so on.

Yep, all extra points of unreliability.

The real relaibility test is, can I ride it home when stuff fails.

You mean like when the chain breaks or a wheel "tacos"?
