A little delay in communication is a good thing. A post via Lilia Effimova and Jim McGee from Rory Perry. Not quite the original point, but one I’ve made recently. [and here]
Speed of light interaction does not leave enough space (ha, space again) for memetic cultivation. A little time is need for organisation to weed out the meaningless from the meaningful in appropriate contexts and establish meaningful links. Survival of the fittest is a great filter, but the fittest will evolve to look a little odd if their environment is to spend their entire life standing on a cliff-top in a hurricane, if I may mix my metaphors.
