        Ok, and I'm fascinated by the question of why we haven't found viable

    There's another possibility: That our brains are computational in nature, 
but that
    they also depend on interactions with the environment (not necessarily 
quantum
    entanglement, but possibly).


Then it's not computational *in nature* because it needs that little ingredient, that's what I'm talking about when saying "Maybe our brain has some non computational shortcut for that, maybe that's why AI is not possible, maybe our brain has this "realness" ingredient that computations alone lack."

It's not non-computational if the external influence is also computational. But the reaction of a silicon neuron to a beta particle may be quite different from the reaction of a biological neuron. So AI is still possible, but it may confound questions like,"Is the artificial consciousness the same as the biological."

    When Bruno has proposed replacing neurons with equivalent input-output 
circuits I
    have objected that while it might still in most cases compute the same 
function
    there are likely to be exceptional cases involving external (to the brain) 
events
    that would cause it to be different. This wouldn't prevent AI,


It would prevent it *if* we cannot attach that external event to the 
computation...

No, it doesn't prevent intelligence, but it may make it different.

if that external event was finitely describable, then it means you have not chosen the correct substitution level and computationalism alone holds.

Yes, that's Bruno's answer, just regard the external world as part of the computation too, simulate the whole thing. But I think that undermined his idea that computation replaces physics. Physics isn't really replaced if it has to all be simulated.

.. the only way to go out of that if for that event to be non-computational in 
nature.
