That could be important for a robot to specialize to new kinds of physical environments, for example. Another reason might be to capture chaotic effects that would only be witnessed with parallel execution. But I'm hard pressed to think of many things that can't be simulated, at least in principle. That's to say it can't be described or modeled, which is to say that conversation about it ridiculous! If not, it's up to the modeler to say specific ways in which a set of primitives are inadequate. >> But, usually when new computer >> architectures are being developed, the developers just write a >> software >> simulator for it in initial stages (that mimics the intended >> physics of >> the hardware design). >> Even the adiabatic quantum computer people at DWave are using existing >> silicon process technologies to design circuits.. >> > > I guess the main creative factor in these examples are the people > involved in designing new specifications and defining symbols > representing aspects of the new hardware they are developing... > But in this context, those symbols can be represented with the old symbols, provided the old symbols were from a Turing complete system (and they are). The notion of introducing a symbol or verb to a computational system is no big deal. It's a primitive in programming languages like Lisp.

That's not to say there aren't new useful primitives to be discovered.
