According to CTV.ca, Bill Gates's book The Road Ahead predicted many things in the future that would involve computers and the Internet. One of those predictions was that anyone will
be able to jump into a map so you can navigate down a street or through the
rooms of a building.
Well, Google Street View has fulfilled this prediction, but not going into buildings yet. That could come very soon, though, and Google is known for their genius ideas, so expect "Interior View" sometime in the future.
