I don't see any problem in attributing consciousness to a robot that
convinces me that it is conscious, in just the same way as I attribute
consciousness to a dog. Animal consciousness such as a dogs only
appear to differ in degree rather than in kind to me. On the other
hand a supposed conscious rock would truly differ in kind, as the
attribution of consciousness gives us no predictive power on their

I also agree with the idea that consciousness is a relative property,
one that is in the eye of the beholder. In the eye of this beholder,
"free will" is an essential property of consciousness, and its hard
for me to see how a Turing machine could have free will. Of course, it
is not necessary to construct robots from Turing machines, but most
likely they will be able to simulate a Turing machine, as the human
brain can do. I really suspect that the human brain is capable of more
than a Turing machine can do.

The simplest operation I can think of that Turing machines can't do is
generate true random numbers (real computers can do this, albeit in
usually in very kludgy ways). I'm not entirely sure that the human
brain can generate truly random numbers either, but probably it
can. This is why I speculate that the random number generator may be
necessary and sufficient for "free will".

And you a proposing that considering rocks as conscious will help find
these qualities too?
