I like this just because its cool, but I agree with your point that just the raw parts with basically invisible electrons flowing through probably doesn't help

I like this just because its cool, but I agree with your point that just the raw parts with basically invisible electrons flowing through probably doesn't help teach. A light up diagram where you can see the signals and their values moving through the network slowly might be a good teaching aid, but I don't think it would help with much other than the absolute basics of "what even is a neuron" type knowledge.
