We agree that the full electricity arrives via the wires (ie we agree not via the silly Poynting field).

What do you mean by "full electricity"?
Do you understand what energy is ?  And do you understand the conservation of energy ?

Main claim made by Darek and that is false is that "Energy doesn't flow in wires"
All 3 points that I made using the science accepted and used by everyone shows that is not true. Even just one of those points alone is enough to dismiss the claim Derek made.

And unless you are referring to IR from the wires no energy from the source travels outside the wire.

Electrons moving trough the wire did all the work.  I think the two parallel capacitors explain best what happens and that all energy flows in the wire.
All is required is to understand what energy is how energy in a capacitors is calculated (the discharged capacitor is like a energy recording device) then all energy will be accounted for and the results shows very clearly that no energy flowed outside the wire other than in this example half of the total energy at the start that ended as heat due to wire resistance.

Me myself i reckon that the energy flows on the surface of the wires (electons)(& electrons), not in the wires (electrons).
Plus i reckon that there is a small amount of energy in the em field around a wire, but not enuff to justify some silly kind of Poynting field source.
In addition the em field around a wire transmits (can transmit) the energy of the electricity on the wire.
If electrons drift inside a wire then that is merely a drag effect, robbing energy. Energy duznt flow in wires.

The workings of capacitors can be explained by my electricity, but can't be explained by silly drifting electrons.

The full electricity arrives when the electons arrive.

You did not provide an answer to what "full electricity" means.
You seems to have guesses about the subject but no concrete mathematical or experimental proof.
This is not unknown science. Is just Derek that comes with ridiculous false claims thanks in large part due to his inability to understand what energy is and he exposes how many have the same gap in understanding (he has millions of views on his videos and multiple other creators make videos mostly agreeing with his points).

Energy flows in to a capacitor not trough a capacitor.

Full electricity is the arrival of my electons (photons hugging the surface of the wire). If u prefer to believe in old electricity (ie drifting electrons) then it is the arrival of the wavefront of the electron to electron push-wave.

I agree that energy flows in to a capacitor when it is charging.
I reckon that energy duz flow through a capacitor – by virtue of induction across the gap.

Ex falso quodlibet, after a contradiction you can conclude whatever.

However, equations are not the question, here. Maxwell debunked the hydraulic analogy for the flow of energy based on experimental data. He noticed that a stretch of wire through which a current was flowing would tend to show a spike of voltage if interrupted at the point of the interruption, just like a pipe experiences sudden pressure at the point where a valve has interrupted the flow. However what hinted him that the energy didn't flow like a fluid in a pipe is that if you coil up the wire the voltage increases, while with a coiled up pipe you do not have this effect. Also, if you put a piece of iron inside the wire coil, the voltage will increase even more, but not the pressure for the pipe coil. Electricity flowing in wires affect other wires nearby not connected to each other either by attracting or repelling them if they too are conducting current, or inducing voltages if the currents vary.

Derek repeated the experiment Maxwell observed, only that, instead of opening the switch, he closed it. And he observed that, unlike a pipe, where the energy would never arrive at 1m/c, the electric energy does, and that the hydraulic analogy is what it is, a (should I say poor) analogy, not a description of How Electricity Actually Works.

So the experimental data debunks whatever theory you may have to sustain your misconception.
