Every year, IBM does a "Five in Five": they look at current technology and where it's headed, and make an educated guess or two about what we're going to see within five years.

Oh now this is just depressing:If you think the idea of french kissing someone over the internet with a robotic tongue is kind of gross, go outside and enjoy your afternoon.
