Technology often does cool things. But it is particularly exciting when technology makes real a classic sci-fi trope. And while we're still waiting on flying cars, Google may be bringing us glasses fit with a heads-up display, able to stream information about one's surroundings in real-time.
Yes, it'd actually probably be really weird, and yes, there are serious privacy implications if people are wandering around with hidden, constantly-recording cameras built into to their eyeware. But come on! A heads-up display! Just like everyone has dreamed of since they played Halo (or Goldeneye, or Doom ... age yourself appropriately)! If it doesn't give me the option to have a red box bracket my conversation partner with "target acquired", I'll be sad.
