 What you're looking at here is an image of someone trying out the Oculus Rift Virtual Reality headset at the Game Developers Conference last week. Now, if I told you last week that millions of us would be wearing these headsets in the next couple of years, you'd say I was crazy. But on Tuesday, Facebook bought Oculus for $2 billion. This isn't a buying out the competition sort of purchase like WhatsApp. This is Facebook making an investment in virtual reality, and so it's only going to get cheaper as a result. Facebook wants these things in the hands of every single user, as does the owner of Oculus, Palmer Lucky. So soon, many of us will be wearing these headsets, especially when they learn that there's a game where you can punch a shark in the face.
