You don't think progress goes in a straight line, do you? Do you recognize that it is an ascending, accelerating, maybe even exponential curve? It takes hell's own time to get started, but when it goes it goes like a bomb.
Frederik PohlThe future depicted in a good SF story ought to be in fact possible, or at least plausible.
