While the behavior of < > such devices can be represented to a limited degree by formal models, < > those models cannot themselves create new categories vis-a-vis the real < > world, and hence are insufficient as category-creating devices in their < > own right. Computations must be augmented by the physical construction < > of new sensors and effectors implementing processes of measurement and < > control respectively. This construction process must be inheritable and < > replicable, hence encodable into symbolic form, yet involving the autono- < > mous, unencoded dynamics of the matter itself. < >----------------------------------------------------------------------------< Is Peter Cariani on the net and is he able to get involved in a discussion of the items in this abstract? I find these claims very open to question - either I am not understanding them fully, or they are debateable.
