I sorta respectfully disagree with his postulate, unless I'm misunderstanding something.
If you ran a cable to the Moon, and turned on a light, it'd take about 1.25 seconds to turn on.
We saw that, when Nixon called Apollo. About a 2.5 second delay (there and back). Admittedly, not using a wire - using radio. But the same principle applies. You can't send messages to the Moon and back in less than about 2.5 secs. Easy maths; 300,000 km (ish) at 400,000 kph (ish).
Video of it
{Side note: Flat Earthers often show an edited clip of that, with the delay removed. They also don't understand that a radio can be patched through to a telephone. Y'know... like they did in World War II. FE are unbelievably dumb.}
You can't send information faster than light. That'd break all kinds of stuff.
Yeah, electrons don't "flow", like we're taught. But stuff takes time. That's why GPS works.
I can confirm that Santa is real. I've met him, in Debenhams. He stroked my bottom.

But the whole point of the video is that the information isn’t travelling along the wire.
It’s travelling exactly 1 meter.

exactly, people are taught that it's the electric charge/ electrons that carry energy in electric circuits - not electromagetic radition (EMR)
EMR used for example in the moon call, seems ok based on my teachings - for now!! until some other magic comes along

For example, if you have two bulbs in the circuit. One on the Moon.
Battery--->---300k km-----Bulb 1
1m
Bulb 2----<----300k km-------I
Are you saying bulb 2 lights (almost) instantly, but bulb 1 takes 2 secs?
If 1 came on instantly, you'd be able to signal to your mate on the Moon at faster-than-light.
