waderoush writes: Over the last decade, just three companies — Google, Apple, and Facebook — have generated most of the new ideas and most of the business momentum in the world of computing. (Add in Amazon, if you're feeling generous.) But it's been a long time since any of these companies introduced anything indisputably new — and there are good reasons to think they never will again. This Xconomy essay argues that the innovation engines at Google, Apple, and Facebook are out of gas (the most surprising thing about OS X Mavericks is that it's not named after a cat) and that other players will have to come up with the underpinnings for the next big cycle of advances in computing. Granted, it's not as if any of these companies will disappear. But the idea that they'll go on generating ideas as groundbreaking as the ones that landed them in the spotlight defies common sense, statistics, and the lessons of history, which show that real innovation almost always comes from small companies. Apple, Google, and Facebook aren't too big to fail — but they may be too big to keep succeeding.
