It's not hard to picture the ancient Greeks considering Pythagoras a mad fool when he proudly announced the world was not flat but, in fact, a sphere.
We may smile now - but what would we have thought as recently as the 1980s if told we'd all have miniature phones in our pockets that we'd watch TV on and use to connect with people all over the world via a vast computer network? Oh, and it'll be voice-activated, know our location and we could use it to find information on any subject.
If it took several hundreds years and supporting voices for Pythagoras' theory to stick, it's taken just the blink of an eye to accept our digital, online life today.
So what comes next?
There's as much fun in the speculation as there is in the finding.
