For simple systems a noemic architecture has very limited value, even with replication. It is no worse but not much better than the traditional architectures. But as we increase in the complexity of the system, and as more and more components are involved, the Noema begins to show it advantages. As we know from software engineering, most of the cost of the system is in the total life cycle and not the original engineering cost. A Noema has the characteristic of elaboration tolerance where a small change is easy to accommodate.
