      Finally getting to dive into those topics I've longed to examine up close. Quantum mechanics is one & my mind is in a painful twist over it. May I ask you QM experts - @gmusser maybe? - to tell me if this article is wildly brilliant or dead on arrival?https://bit.ly/2wCk7yO

      For my part, my next book will, among much else, discuss whether quantum physics has some role to play in the mind. I'm more sympathetic to that idea than I used to be, but all such theories take a philosophical leap. They are variants of what philosophers call identity theories.

      Very curious as to why you are more sympathetic than before to this idea. As far as I understand, there is no evidence from neuroscience for this.

      I think theories of consciousness are at a very early stage. All are probably wrong. We need to look at what each does well, rather than dwell on failings, and build on that. Penrose and Hameroff draw attention to intracellular structures and deviations from Hodgkin-Huxley. (2/2)

      I don’t see how QM makes consciousness easier to explain. Making computation nonlocal or faster still only gives you computation. It’s just implementation details. Looking at implementation intracellular structures and also the extended mind may explain capabilities though.

      I am still fascinated that Turing (1950) discusses telepathy as possibly real. If it is, it would require changes to foundational physics (superdeterminism is probably not enough), but not to computationalism. Transistor based computers can be conscious but not telepathic.

          When there is a (sender, receiver, message, code) telepathy is ordinary communication. Turing's belief is equivalent to thinking different humans can have fundamentally different hardware. And that was before biology and genetics were scientifically grounded.

          If telepathy were possible, in the sense that the exchange of mental representations is not restricted to local electromagnetic interactions in the usual photonic space, could you be fully certain that minds can be realized independently from each other, in an individual brain?

          Is there a leading historical theory on why he discussed it in the article? I remember reading it - in my memory he just dropped it outta nowhere at some point. Leaving me amused but clueless.

          In Turing's time, telepathy was not yet seen as totally outlandish, and most people outside of science will still tell you that telepathy is unreliable but real. I have a strong prior against telepathy, but only because it is very hard to make it compatible with known physics.

          The idea of a quantum computer is basically that the particle universe is inefficiently implemented on the quantum substrate universe, and by directly interfacing with the quantum world we can perform some operations much more efficiently. But it is still just computation.
