Lossy compression belongs on the Sequential Decision Theory side of the ⊗ just as does the fitness function of evolution belong on the decision side of biological evolution. It's a matter of economics -- of engineering -- of technology -- of "ought" but NOT of "is". "is" belongs on the AIT side of the ⊗. "is" is lossless but only with respect to the data provided by the evolutionary process in the form of sensors. The cognitive process also has economic constraints about what data can be retained -- memorized -- and that _to_ involves a "lossy" process that limits what AIT can do -- even given infinite resources, which are not available to AIT in any event. But that doesn't mean AIT throws data away -- it just means AIT never has certainty that it has achieved the smallest, lossless, memorization of the data provided by evolution. So, the presence of "sharp boundaries" depends on one's ability to draw the corresponding distinctions. For instance, humans unaided by technological civilization draw "sharp boundaries" between green and red but do not between UHF and VHF photons. Once again my dear Mr. Rose, we are discussing sensors and measurements -- not compressors. You are militantly category error-prone on this topic.
