On this subject, I'm interested in where CYC fits in.  Hasn't the cyc
"baby"
been running for a number of years?  I really should look this up myself,
shouldn't I?  I will.

 So, the connectionists tried to create machines and
structures modeled
after the brain, but they didn't get too far.  Let's say that you build
an OS and a programming language that allows you to accurately model a
brain.  If you stick a human brain in front of a newspaper, you get
nothing.  So add some input devices and actuators.  Now you stick a baby
in front of a newspaper -- still nothing.  So let the baby run for a
while, experience a variety of sensations, make a whole bunch of
associations, stick it in front of many newpapers and many non-newspapers
for many years, and finally you get a pretty good character recognizer.
