That kind of straw man, that consciousness only emerges from electrical signals, is one of the reasons we haven’t reached AGI yet because we keep underestimating it. There’s way more biological, chemical and physical phenomena going on in brain that gives way to consciousness than just neurons firing ions.
Electrons are not the question. The question is have we modeled it well enough. As of yet to my understanding there is no physical process that requires more power than a Turing machine.
