Hmmm. I was talking about genetic evolution. You seem to be talking
about memetic evolution. Even so, you're talking about what choices
lead to more progeny for a particular culture, rather than about ethics.
I agree that success is useful and important. But it isn't the
standard basis for ethics. I'm willing to concede that success is
usually consistent with ethics, but I don't think it's the right yardstick.

I don't have a scientific test. I'm willing to argue about individual
cases (though not ad infinitum) and follow general rules. Ceding rights
to infants and comatose patients is one of those general rules.

I understand that we are meat computers, so proving that parts of our
response are algorithmic doesn't undercut our sophistication. If a
program says "ouch", but doesn't produce any other grammatical
utterances, then the sophistication of the code doesn't matter to me.
If a program can pass the Turing test, but doesn't have opinions that
outlast the session, then it hasn't convinced me. (The Turing test is
interesting, but it's not sufficient.)

I said earlier that my default standard is self-awareness, and that
others might believe awareness of pain would be sufficient. You'll have
to find someone who believes in the latter standard to argue about the
status of your program. To me, it's too simple to count.
