But it's quite a different thing to put money on the line to back up those predictions, which is exactly what this British bookie has done. Think you know whether Google Glass will beat the iPhone, or whether we'll be ready to go to Mars and back by 2020? Now's your chance to capitalize on those predictions!" Or you could, y'know, invest money in at least some of them, and thereby increase their chances of succeeding.
