    Ilya Sutskever is wrong on this. The brain is not a digital computer and not really a computer at all, more like a quantum orchestra. Biology is based on organic carbon which supports quantum processes and self-similar dynamics in hertz, kilohertz, megahertz, gigahertz and

    Ilya Sutskever, in his speech at UToronto 2 days ago: "The day will come when AI will do all the things we can do." "The reason is the brain is a biological computer, so why can't the digital computer do the same things?" It's funny that we are debating if AI can "truly think"

    Microtubules are actual biological structures in every and all cells which utilize automata functions, classical and quantum to orchestrate living matter to have conscious moments. I told Stephen Wolfram about it in late 80s at Los Alamos.

    Maybe consciousness is just geometry learning to feel. Hameroff finds it in microtubules. Wolfram maps it in automata. Oxygen might be where both converge.

    Dinner last week with Roger Penrose in Oxford. He discussed new findings in CCC theory, twistors and Eschermatics. I tried to convince him his OR prompted the origin of life.

    Consciousness in the brain is a hologram generated by interference among quantum oscillations in spacetime geometry from laser-like coherence in microtubules in cortical pyramidal neurons.

    All animals and plants have microtubules and are conscious, just at lower frequencies, intensity and content. We humans have 10 million Orch OR moments per second. A sunflower a few per minute.

    Why are we still making a distinction between consciousness and any other physical or biologic process? This is anthropocentrism at its core. But we're just not that important as humans.

    Plants have microtubules and their phototropism is inhibited by anesthesia. They probably have ten conscious moments per minute. We have 10,000,000 per second.

    Do plants have minds? Can we see past our soul-blindness to recognise plant minds? In the 1840s, the iconoclastic scientist Gustav Fechner made an inspired case for taking seriously the interior lives of plants aeon.co/essays/can-we-… (via @aeonmag)

    Fungi make intelligent decisions. No neurons, but lots of microtubules (MTs). Quite likely MTs oscillate, entangle and have Orch OR conscious moments, far less frequent or intense than ours. (Though some fungi have psilocybin.) @jackieappel

    According to this graph, plants have one conscious moment every few minutes. Most humans have them 10 million per second. You, I’m not sure.

    Very much agree that life and consciousness are marginally discernible, particularly when biology is viewed as a vehicle for the expression of awareness rather than its origin.

    I sat outside the studio during Roger’s interview. @joerogan Joe didn’t want to talk to me. Maybe because I’d say mainstream neuroscience, AI and philosophy are clueless about how the brain works. It’s not a complex computer of cartoon neurons. It’s a quantum orchestra of

    Consciousness didn’t evolve. It preceded life and prompted its origin and evolution. Feelings drive behavior.

    Evolution doesn't involve novel things supernaturally springing into being, it instead involves gradual change via weak emergence.

    Consciousness can be defined as what goes away under general anesthesia and returns when the anesthesia is gone. You might complain that’s too restrictive to biology, but consciousness depends on organic carbon chemistry essential to life. Organic carbon brings the quantum in

    Not sure if AI can become conscious, but: if it acts just like it's conscious, how would we know or prove that it isn't? We'd need a non-behavioral definition of consciousness that could still be tested but wasn't so restrictive it could only apply to biological entities.

    The ‘higher level’ communication @MichaelLevin studies is almost certainly related to higher frequency megahertz and gigahertz oscillations and entanglement among microtubules in different cells. Michael uses static fields, a special zero frequency case for microtubule time
