Fitness still applies (Lamarckian agents compete with Darwinian), so
merely desired won't cut it. You have to guess the future fitness landcape.
Computationally, a hard task.

automatically emerge in this spacetime. Of course, it takes a long time
before mere replicators become effective Darwinian agents.
