Human competition is eternal. We thrill to victory, we suffer the
agony of defeat. No matter what the future brings, sports will be a
part of it. But what forms will these games take? Who will be the
spectator, who will play? Will aliens be our opponents or machines?
Will physical competition even exist? What rules will we play by? What
will be at stake? What rewards will be reaped by the victors? What
fates await the defeated? Will the entire universe be our arena or
will our world be smaller than today? Visionary authors speculate on
what swifter, higher, stronger, and winning will mean in the near and
distant future.
