Wrong. All I suggested is that neurons are not simple logic gates and
may use quantum computing techniques internally. The conjecture is not
unreasonable and, if it can work to advantage, would be naturally

OK, post some. Show how a bunch of pulses in a nerve bundle convey

The whole singularity thing is a red herring. It's a symptom of the

It is likely that the computational singularity exists somewhere in the
future of computer hardware. When I was an undergraduate the idea that a
computer could beat me at chess was risible. Now any one of a dozen
chess engines is stronger than our best human world chess champion.
David Levy only just won his bet. Turns out though that computer chess
was a false dawn and is an easier problem than we first thought.
Go requires much deeper pattern matching skills to play at any kind of
serious competitive level and computers are way behind human masters.
More impressive still are the self driving cars which are just into road
trials now. Even with some bugs they may be safer than humans.
A few things like highway collision avoidance, maybe warnings and
applied braking, might be good. I can't imagine a self-driving car
being feasible in a dense city.
It might well work best there since the average speeds are low and
predictable vehicles can convoy together much closer together under
machine control than with human reaction times 100-1000ms.

Too many drivers these days are using cell phones or worse texting.

The model of a brain as a bunch of threshold logic gates (the Neural
Network approach) is silly. Prop delay alone makes the idea absurd.
Single-celled critters can do pretty cool adaptive stuff.
It is only silly if you choose not to understand it.
The brain must be quantum mechanical at the cellular level, with all
the mysticism and noncausal behavior of quantum mechanics.
New age weirdo thinking. Presently advocated by Penrose in his various
popular science books. I remain unconvinced. The crux of the complexity
of a human brain is a huge number of tiny simple computing elements and
the insanely large number of permutations of possible interconnects.
Single-cell and few-cell brainless critters do impressive things, like
hunting and hiding and defending themselves and finding mates. Why
Complex apparent behaviour can emerge from the interaction of a few very
simple rules. Conways simple 2D automaton Life is Turing complete.

would neurons be limited to acting like slow majority logic gates,
dumber than a bacteria? The Neural Network model is popular because
people don't understand how cells actually work; it's cargo cult
science. What might the image recognition processing time be for a
trillion element neural net computer with millisecond element prop
delay? It wouldn't win many tennis matches.
Yours is the cargo cult science. Anything you presently don't understand
you put down to handwaving quantum mysticism.
Wrong. All I suggested is that neurons are not simple logic gates and
may use quantum computing techniques internally. The conjecture is not
unreasonable and, if it can work to advantage, would be naturally
selected. It's interesting what hostility that suggestion invokes.
There is no compelling reason to invoke anything more sophisticated than
a lot of non-linear differential equations to model neurons.
OK, post some. Show how a bunch of pulses in a nerve bundle convey
sound and sight and sensation. Cover consciousness while you're at it.
Why wouldn't neurons use quantum computing principles inside? If it's
possible, evolution would have taken advantage of it. So you are
saying that it's not merely a weird idea, but it's impossible. Pretty
strong statement.
I am saying that on the scale of a typical cell quantum effects are
largely limited to the individual molecules.
DNA is a molecule. Enzymes are molecules. That's what we are made of,
molecules.
There is no cellular aura
of new age quantum mysticism needed to explain what is observed.
This could change but at the moment it looks exceedingly unlikely that
anything other than the huge network combinatorial factors are relevant.
