I still relish this true story of progress: my father, who started programming with punch cards in high school that he had to send off to the nearest university and wait a week for results, now has a computer in his pocket with orders of magnitude more computing power and capacity, plus it's connected to a storehouse of information that one could not exhaust in a lifetime. Sure, optimists will predict more favorable outcomes, but as XKCD (rightly) says to those asking "where's my flying car?", the answer is: we have helicopters.
