We've all seen Star Trek, and some of us are a little too keen on the universe created by Gene Roddenberry. But whether you're a fan of Star Trek or not, you can't argue against the fact that the various different iterations on the original series as well as the subsequent movies had a knack of predicting some of the technology that we all take for granted today. Star Trek has its characters using tablets before the iPad (or even Tablet PCs, too) and voice recognition was being used on our TV screens before Siri and Google Now were even close to being announced. Skype didn't exist, but those on the bridge of a Star Trek ship could talk to people on giant screens, just like we can today.
