Well seeing as how they are using it in Star Trek and that takes place in ~2265, we've got a few hundred more years.
As far as "confusing and boring" I think that depends on the implementation. I've been using WinMo8 for the last 6+ months and there have been a few gotchas but for the most part, the interface is a lot easier to use than iOS6. Although I think that has more to do with the UX and not the UI. I love apps that TapBots make but I don't have the patience and artistic talent to create interfaces like that. My developer hat says it's definitely a lot easier to program apps Flat, but it's very easy to do it incorrectly. You're not alone, but now that Apple opened fire on Skeuomorphic design  and lots of people look to Apple as design leaders, I feel like you're going to se a lot more flat.
Personally I don't like the 'bubblegum' of the iOS7 previews I have seen so far. I'm sure my daughter will love it but as a William Gibson loving tech nut it leaves me feeling a little left out in the cold... Be that as it may, this is what I wanted to say to you: people seem to think of jeweled buttons and gradients as skeumorphism but I find that to be something of a narrow view.
Example: my favorite skeumorph in OSX - type in an incorrect password at the lock screen and the little thing 'shakes it head' as if to say: "uh-uh, try again" such a light touch and so playful and benign at just that moment that the user is feeling a tad aggravated. How much better is that than a giant red 'X' an an ominous warning gong?
Skeumorphism in today's design circles is pretty much the definition of the phrase: don't throw out the baby with the bath water.
