Why is there never any fundamental research whether human intelligence is even computable? All these huge, expensive projects based on an untested premise.

>>yters+GI
Why wouldn't it be? It seems to me that at worst we would have to wait for computers to become as powerful and complex as a human brain, and then simulating human intelligence would be a matter of accurately modelling the connections.

Is there doubt as to whether a neuron can be represented computationally?

>>radekl+SJ
Yes there is doubt. Can you say for sure that we have a complete model of all physics, and that all physics can be represented computationally? We're still discovering new features of neurons at the quantum level. Who knows how far down it goes. There may be some unknown physics at play inside neurons that can not be computed by a Turing machine. https://www.elsevier.com/about/press-releases/research-and-j...

There are aspects of quantum that we don't understand, but we have no reason to believe intelligence relies on them, any more than bridges do.

>>Jeff_B+nR
We actually do have reason to believe that, since our current understanding of consciousness is very incomplete. Human consciousness extends far beyond our current understanding. I am referring to the full extent of the capabilities of the human mind, not some isolated aspects of it.

The physics of bridges is well known. That is basically a solved problem. Human consciousness/intelligence is an open problem, and may never be solved.

> We actually do have reason to believe that [intelligence relies on quantum properties]

Are you leaving the reason unsaid, or am I in fact reading your argument correctly: "We don't understand consciousness, and we don't understand quantum, therefore it is likely consciousness relies on quantum." There's already plenty of mystery in an ordinary deterministic computation-driven approach to intelligence.

>>Jeff_B+F01
No I'm saying: "We don't have a perfectly accurate physical model of consciousness, we know that physics is incomplete, and our current model of neurons extends to the lowest levels of known physics, therefore there may be unknown physics involved in consciousness, and those unknown physics may not be computable."

>>random+eh1
I clarified it in my latest reply above. The original comment asked if there is any doubt as to whether a neuron can be represented computationally. We don't know exactly what a neuron is, and are still discovering new subtle mechanisms in their functioning, and they are part of the most complex structure in the known universe, therefore of course there is doubt.
