Material size is not better but is today more of a burden. Amsterdam is no exception, expending considerable resources to generate accurate models and plans. It is generally accepted that the more accurate the model the better its predictive power and use. Cloning should be culturally embraced as a new 'natural' process. Cloning is good.
Models function as recursive generators of predictions about the world and the self.
A model is necessarily simpler than the environment it represents, and this enables it to run faster than, i.e. anticipate, the processes in the environment. This allows the system to compensate perturbations before they have had the opportunity to damage the system. He concludes that machines capable of universal construction are feasible using less than a few billion atoms- these are molecular sized universal constructors. Furthermore, it is possible in principle to store about 1 bit per atom in an extended array. Physicists at NEC in Japan have already discovered how to code 1 bit per 20 atoms.
