The microworlds are also known by other names, including "synthetic task environments", "high fidelity simulations", "interactive learning environments", "virtual environments", and "scaled worlds".
Zeh further claims that decoherence makes it possible to identify the fuzzy boundary between the quantum microworld and the world where the classical intuition is applicable.
These microworlds progress rapidly, some dying out in revolutions and wars, and some developing as regular civilizations without any of them showing any intrinsic perfection or happiness.
For example, overcoming combinatorial complexity is such a fundamental problem in study of expertise that even a microworld like chess can shed some light on it...
