> We pass signals in our brain, they can cross from neuron to neuron in about 10ms
Could you clarify this point for a non-biologist? I understand the neuron-to-neuron transmission is not going to happen at the full electrical conductivity rate (something like 100 m/s) but this seems so much slower as to be hard to understand as a lay person.
Simple: signals travel through the brain through to a kalium-natrium cascade reaction (not even a real chemical reaction, just a gradient change), and every time they hit a synapse it becomes a lot more complex involving a dozen plus neurotransmitters. (This is why a kalium/potassium injection will kill you: it reverses the gradient for a long, long time, meaning the nerves cannot fire during that time, which means your heart and breathing (and everything else) stops. Incidentally, this also fires every pain nerve in your body so it should be unbelievably painful, and survivors do report that. Kalium is the Latin word for potassium)
Electrical conductivity is barely used at all. It is used in the processing of the resulting signal, but not in transmitting it. Even that part is very different from a current on a wire or through a transistor.
