Overview

PBS Space Time examines Roger Penrose's idea that consciousness arises from quantum processes in the brain, and reviews new evidence about microtubules. It ends with an estimate of what replicating consciousness would demand.

Pointed to as a clear, balanced overview of quantum-brain theories when AI consciousness and brain models come up.

there is a theory by the brilliant Roger Penrose and extended by others that the brain is just not neurons but also quantum effect which would make it impossible to emulate via current technology excellent PBS Space Time on that * [VIDEO]

There's a few videos by Sabine/Anton and also now PBS about Microtubules and conciousness, it's starting to gain ground and If I were an AI company right now I'd be having cold sweat. Video of reference (check especially the ending summary where they calculate more or less how much would be necessary just to replicate a human mind's way of achieving conciousness if microtubules in fact contribute towards it): [VIDEO]

sociopaths sometimes study people to learn how to emulate emotion that's exactly the state of "AI" right now, it's cold, mathematical emulation btw there are some fascinating papers on the concept that consciousness in humans is actually a quantum effect brilliant Roger Penrose proposed it (and they thought he was nuts) but recent discoveries about microtubules make it plausible so who knows, maybe a dozen exponential improvements in quantum computers could make "AI" really conscious next century * [VIDEO]
