It is a pedestrian observation that people appreciate criticism much more if it is not directed towards something they relate to. In my last essay, I concluded that replicator<-->vehicle is actually very limited paradigm, and received an answer from Mr.Deutsch that ended with conclusion: "Hence the unavoidability of the von Neumann replicator-vehicle mechanism and the futility of attributing evolution to the vehicle." That mechanism may be mathematically provable necessity to describe accurate self-reproducer, but it also may be totally agnostic with respect to mechanism that causes the inaccuracies, ie which drives evolution. Or is it also mathematically/logically provable that inaccuracy in self reproduction must be random in its nature? Is it prescribed by this model what causes variation, or is it open for some other model to give an answer to that question? In fact, already the choice of the term variation vs inaccuracy has different connotations and implies or s...
