In this universe, computing Life has very definite costs. Whether you build a
dedicated machine, representing state and state transformation in hardware,
or use a recursive lightcone hash lookup (as Life state distribution is very
different from random, and which has very real penalties of its own) you 
have to represent the state and compute changes on that state.

If our Planck scale looks roughly than Life the costs are stupendous indeed.
