I guess I did ask for some examples, and this is one... However...
I am aware of Penrose’s wild speculations. It is likely quantum processes are involved in some structures deep within neurons and optimize when neurons should fire, similar to the way Chlorophyll uses quantum mechanics to absorb light. Note, the fact that Chlorophyll uses quantum principles does not keep us from developing Solar Cells, which by the way, harvest light 10-20x more efficiently than the best plants. The idea that the whole of the brain is in some highly entangled state involving billions of neurons is a wild flight of fancy given the molecularlarly noisy and hot environment the brain is. We are also on the verge of having true Quantum Computers, which I doubt are needed for Strong AI, but will likely hasten its arrival by optimizing the rules needed by non-quantum computers.
We now have self driving cars, Computers that identify images better than humans, Deep Blue could beat the best Chess player in the world in 1997. Watson won Jeopardy! in 2011. But somehow you suppose that Quantum Mechanics (or other unjustified hand waving speculation) is needed on a massive scale to emulate intelligence.
Even so, we will have Quantum Mechanical computers soon, so even that isn’t a stumbling block if it were a necessity.
Since it is largely only human creativity and independent problem solving that are really the only missing elements to Strong AI currently and these are traits also largely missing in animals. What enormous evolutionary event occurred that allowed Humans to think so well? It seems largely to be just one of scale. Our brains are bigger and we passed some critical threshold to develop and hold advanced abstract concepts in our brain, an advance that went hand and hand in parallel with the emergence of sophisticated language (both driving the other). I speculate that aided by us, computers are on a similar path to pass criticality when it comes to intelligence. I further speculate the ability to better model abstract concepts will be the final threshold for Strong AI – some sort of Meta-Meta-Abstract recursion for representing concepts symbolically.
