I was just pointing out the difference between Life pseudocritters and the truly evolvable patterns that could exist in a Turing machine that happened to be implemented on a Life grid (as opposed to on an erector set, or in macros of the Unix text editor "vi", or any of the other substrates that have been demonstrated to support Turing machinery). The difference was relevant to some silly debate about disingenuousness that we were having back in the distant past before my son died... -- brian@holtz.org http://humanknowledge.net
