 Notably, arguments for unlimited pancomputationalism rely either implicitly or explicitly on the simple mapping account of computation. They assume that an arbitrary mapping from a computational description C to a physical description of a system is sufficient to conclude that the system implements C. In fact, avoiding unlimited pancomputationalism is a major motivation for rejecting the simple mapping account of computation. By imposing restrictions on which mappings are legitimate, other accounts of computation aim to avoid unlimited pancomputationalism.
