You guys you guys you guys...
I don’t want to intrude here but am compelled, I would bet half of what little net worth I have to say that human cognition (partially) relies on a network of quantum superposition optimization. I would look for evidence of this in DNA splitting/repair and in tracing the evolution of neuronal cell functionality looking into the evolution of QIT optimizations in photosynthesis, purple bacteria, etc. and in the mathematical modelling of human cognition timing "holistics" with evidentiary femtosecond/attosecond spectroscopy metrics. I would try to prove that “out of band” quantum optimizations are needed for GI in the holistic spatiality of our evolutionary wetware EM network architecture, perhaps not needed for AGI in an electronic, non-neuroscience based, computer architecture. These EM wave mechanics signaling findings are very interesting! But the quantum pieces are still missing IMO. With the quantum pieces missing you would still be computing around a model of brain signaling. But, I don’t know much about the EM signaling computational perspective so will read into it... I’ve recently been digging into dynamical systems signaling so I’ll throw some EM quasistatics in there :) John From: Steve Richfield [mailto:[email protected]] Sent: Wednesday, March 15, 2017 10:22 PM To: AGI <[email protected]> Subject: Re: [agi] Field dynamics ... the empirical proof (Science Mag).. Mike, Colin, et al, I still see absolutely NO evidence that fields, Hall effect, etc, etc., aren't just part of a computational process, just like the nonlinearities and thresholds of FETs, etc., are just part of conventional computers. A more appropriate comparison would be to Analog Computers, that produce VERY precise results despite using very imprecise components having all sorts of strange electrical characteristics. WAY back at the 1st NN conference in San Diego I published an article explaining how dendrites operating independently could by performing as part of an probabilistic OR of probabilistic ANDs function - that a particular neuron could be performing several unrelated functions - one for each dendritic structure. Since most propositions are almost always FALSE, the noise introduced by presenting the probabilistic OR of several such functions would be washed away when the outputs are then ANDed with other such functions. The benefit here would be a LARGE reduction of metabolism - simple power and space reduction. Implementation detail. However, I don't see any benefit for AI/AGI systems copying this approach - unless there ends up being a really high overhead for bus drivers. However, this discussion DOES address how some functions that we KNOW are being performed might be working despite our not finding any mechanism when looking through microscopes. A good example is mutual inhibition, that the Hall effect would explain nicely. Another good example is stabilization - with SO many interconnected high gain components, why don't brains simply lock up or oscillate uncontrollably (which some do, which we call epilepsy). Field effects would explain this nicely. So, I am taking a middle position - that field effects have a BIG part of neurological computing, but I still believe the result to be fairly precise analog computing and NOT some sort of field process that doesn't involve fairly precise computing. Look at these effects as components and NOT part of something mystical. Of course this means that there is more functionality than many people thought was there, but I don't know ANY researcher who thought that we already had most of the pieces of this puzzle. This stuff DOES affect AGI, albeit slightly, in that AGI will have to deal with many/most of the same issues if/when it progresses close enough to optimized functionality to experience lockup, oscillations, etc., and the operation of fields, Hall effect, etc., will probably provide some useful programming clues - to programmers are astute enough to pay attention. Am I alone in this belief?

I've never quite bought into the brain being a "computer that is processing information" either. I've always liked reading Colin's and Dorian's myth busting comments over the years. Keep it going....
