I'm curious if this SPoF theory stops at computer/real world interfaces (such as the control surface <-> computers). Or if this generalizes into purely computational models. In my mind I can't find any purely computational model using distributed techniques that succumbs to the SPoF "theory." But the computer/real world interface is trivially obvious in just about every context.
