Please allow an outsider to comment on the
implications of GEPR's analogies in his life-cycle message. The analogies
are attractive. They may also offer a
will-of-the-wisp.
I speak as someone who worked with both Swarm and
Repast, several years ago, to do ethnohistorical models of trade and
band-survival patterns in a plains-like environment. To make this
increasingly interesting would have required modelling something like speciation
or ethnogenesis. John Holland never really produced this. For that
reason, the rhetoric of GEPR's analogies is enticing. It actually hints at
producing emergent species that are not encompassed by (that is, in the ugly
word, "built in by") a naive pre-specification of the outcome. Like a
novel species among the fish in a modelled stream.
Perhaps a more careful analogy would keep things
within bounds.
