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.
