"There won’t be many other Stuttgarts. Gerontocratic society lacks the will and energy to innovate on the grand scale. Unless, as with Stuttgart, some large city is leveled by a cataclysm and the survivors have no choice." Paul shrugged. "Not a pleasant prospect! There may be some fanatics who consider holocaust an acceptable price for change, but I’ve studied holocaust, and holocaust is vile. The change we face has its own inexorability. There’s much to be said for survival. Live long enough, and reality will melt beneath your feet." He paused, considering. "I’m very fond of Praha. That city surely has lessons for the world as profound as Stuttgart’s. Praha outlasted its own epoch and became a beautiful freak, a charming atavism. Praha found a second chance. Now Praha is the chrysalis for a larval form of posthumanity."
