Hi,
If you replace each neuron of the brain with a silicon
counterpart until the brain is entirely silicon based.
Would there still be qualia or self-awareness in the
brain like we normal human have? What do you think?
How do you plan to do that? Silicon is not electrochemical nor does
it respond to small molecule neurotransmitters like GABA, glycine,
glutamic acid, serotonin, aspartic acid, acetylcholine, melatonin,
dopamine, epinephrine, norepinephrine, adenosine, anandamide;
endorphins, enkephalins, dynorphins, cholecystokinin, vasopressin,
oxytocin, etc.
What I meant by silicon was neuron made out of pure silicon
or in other words.. integrated circuits... noting that a
microprocessor
is an integrated circuit built on a tiny piece of silicon. So a
neural electronic circuit is made out of silicon rather than carbon.
About Serotonin and stuff. If they use other ways for neurons
to communicate and not via synapses and neurochemicals
and neuromodulators perhaps using radio waves or other
molecular equivalent.. then it can replace the functions
of those neurotransmitters and neuromodulators. Or other
ways.. how else can they create those androids in other
parts of the universe (there are 100 billion galaxies.. the
most sophisticated androids have almost 100% probability
of having been built already).
Or maybe cellular circuit is the ultimate nanotechnology
in the universe and silicon based circuitry are just
imitations. So to match the human brain, the android has
to be bigger.. like perhaps the Transformer robots to
put up more circuits inside that can match humans and
beyond. Whatever. A giant androids with more circuitry
than the human cellular nanotech equivalent would be
more intelligent. We are just more compact.
But the bottom line and $1000 question is.. Would a
pure machine mind have qualia or subjective experience
like we do? What do you think. Ignore the other paragraphs
above as this is the primary question of the thread.
Reductionism is absurd, doo doo ex machina. The brain is not a chip
any more than an ant nest or a beehive is an ant or a bee,
respectively. Can you mimic a single ant or a bee? They can see.
Model a slime mold going from its wandering independent amoeba phase
to its aggregated differentiated reproductive phase. There's damned
little brain in any of that - and you still can't do it. What happens
if you make a brain that is deaf, blind... It will go insane (or
Southern Baptist).
How do you plan to fabricate circuitry that mimics the orchestration
of small molecule neurotransmitters like GABA, glycine, glutamic acid,
serotonin, aspartic acid, acetylcholine, melatonin, dopamine,
epinephrine, norepinephrine, adenosine, anandamide; endorphins,
enkephalins, dynorphins, cholecystokinin, vasopressin, oxytocin, etc.?
