This is old news, actually. I came across an article posted on January 2014, that talks about a theory… i had just no idea existed, and it blew my mind.
It’s called Orch-OR: the idea? you cannot model consciousness with just a huge neural network. There’s an orchestrated quantum effect that affects synapse.
This theory was proposed by Roger Penrose in the early 90’s, and… cool thing is that, precisely, quantum vibrations inside brain neurons have been proved to exist.
(I know, 2014, i came late to the party!).
