Point well taken. But I meant to contrast the relatively instantaneous and
universally interlinked communications that we now enjoy, with the
intermittent and broken communications that will probably characterize
post-diaspora humanity. I do not claim, pace your application of relativity,
that communication will prove impossible. When our various quasi-transcended
children, diverging copies, and future selves try to phone home from far
galaxies, however, they will *not* enjoy the functional equivalent of a
long-distant call!
