I just joined this list after Amara Angelica from KurzweilAI pointed out
that there was some talk about GAC on this group. I've looked at some of
posts and would like to make some comments:

1 - GAC is a black box. I have made no disclosures on what it uses for
pattern matching (not that it should matter if you place any value in
Turing Test which bars knowledge of the internals of a system.) But, for
record, I am doing experiments now with SOMs and SRNs.

2 - The primary purpose of GAC is to build a fitness test for humanness
in a
binary response domain. This will in the future allow GAC to babysit a
evolving artificial consciousness, rewarding and punishing it as needed.

3 - The key to evolving anything is the fitness test. If I want to
evolve a
picture of the Mona Lisa, then I need a fitness test for the Mona Lisa.
good fitness test for the Mona Lisa would be a copy of an image of the
Lisa. To rate the quality of an evolving picture, I would just need to
compare pixels. The next best thing to using an image would be a random
sample of pixels; the larger the sample, the better will be the evolved
copy. Right now, GAC is a 350,000+ term fitness test for humanness. At
one of those points GAC knows what it should expect it were testing an
average human, because for each one of those points GAC has made at
least 20
measurements of real people.

4 - Any contradictions in GAC are real contradictions in us. It can't
believe anything that hasn't been confirmed by at least 20 people.

5 - GAC is science. Over 8 million actual measurements of human
have been made. There are at least two other projects that claim to be
collecting human consensus information - CYC and Open Mind - neither has
actually done the science to verify that what is in their databases is
actually consensus human fact. It's all hearsay until the each item is
presented to at least 20 people (central limit theorem.)
