All subsequent knowledge in the system will be descended from the initial knowledge. So all knowledge in a knowledge-growing system must be either created by or comprised of replicators.

If other criteria for the selection of conjectures were built into the system, such as in the genes of a human, the growth of knowledge would be bounded to only conjectures meeting those criteria, even if the variation/conjecture aspect of the process were proceeding via a random process with no built-in knowledge. Fixed criteria means bounded knowledge, means no universality. So for unbounded progress (universality), the criteria must also be varied. But how are they criticized? What criteria for their selection can there be to avoid a regress, except survival?
