Read instead that the brain makes 100 trillion calculations in
parallel, constantly, and analog rather than digital. And that's only
pre-synaptic potentials contributing to post-synaptic membrane
potentials, and THAT is modified (and modifies, in feedback)
contributions from neurotransmitters, and we're just getting started.

What is consciousness?
You think you know, but you can't give a definition (being a reduction
in abstraction) comprised of objectively measureable criteria.

And you think you know what consciousness is when you see it, but how
can you be sure? You can't experience someone(-thing) else's internal
state, so you don't know if the behavior you observe is consciously
controlled or completely determined by programming.

That's an empirical question. I'll bring the brain, you being the
consciousness meter.

Now that'd require a digital consciousness meter.

} Sorry, I have this sort of question from time to time.....

You want to see an acceptable artificial
life/intelligence/consciousness? Create a robot capable of acting
enough like it to convince most people, then make it soft and fuzzy
and warm and huggable, and people will accept it as such. Peoples'
acceptance can be measured. "Consciousness" can't. Of course
scientists who stand to gain by maintaining the argument will
disagree, but when they do so most people will either ignore them or
tell them to shut up, and hug their electronic friend.
