I think "X simulates Y, therefore K(X) > K(Y)," is pretty unambiguous in
its meaning, and it's wrong. Also, two AIs certainly could conduct a
dialog by simulating each other, if we're talking about Turing machines
with infinite tapes.

"Kolmogorov complexity" does not refer to the same thing as the English
word "complexity." In particular, doing more things can actually
decrease your Kolmogorov complexity. A program that outputs Wikipedia
would be pretty long, but a program that outputs every string, including
Wikipedia, can be very short.
