The brain is a bit more complicated than a piano. With 100 billion neurons
each with at least 1000 connections compared with a few thousand circuits
in an electric piano the brain is at least a few billion times more
complicated. If your premise is that something as simple as an electric
piano shouldn't be capable of having a mind then I think I would agree with
you. However, since the brain is a few billion times more complicated I
would place little value on your analogy.
Personally, the thing that I have always had trouble with is how a
sophisticated organ like the brain has so much trouble adding two three
digit numbers together. I wonder more at how consciousness can be so
simple and slow when the brain appears to capable of so much more.
Joe Dees argues that in fact consciousness does arise because of increased
complexity. He has offered a hypothesis that humans are distinct from
other animals because our brains have reached a certain level of complexity
which results in consciousness. He points out that only humans and a few
primates are capable of recognizing their own faces in a mirror as
evidence of self-consciousness. Personally, I don't think the mirror test
he points to really is an indicator of something as sophisticated as
consciousness. I think it points towards a specialized ability to
recognize external visual representations which humans are better at. The
model test is the better analogy. No primate other than a human is capable
of recognizing that a miniaturized model of a room and the placement of
objects in it correlates to a real room. Some primates are capable of
making the leap with their own faces because facial recognition is so
important in primate society.
I really do not know what creates a consciousness or understand what does
and does not have one. Unlike you though, I am sufficiently impressed with
the known physical world to accept that a consciousness can arise without
resort to a new law of physics.
As I have said before though in the study of memes we should concern
ourselves with the existence of a non-genetic evolutionary system. There
is nothing about evolution that requires consciousness. Our studies should
focus on transmission, variation, and selection of memes. The study of
consciousness is peripherally related at best and should be left to
cognitive scientists. While this field should certainly take note when a
consensus answer is arrived at, memetics will not be the place where that
consensus is found
