Let's talk about some scenarios.
By 2010, computers will disappear. They will be so tiny that they will be embedded in our environment, in clothing, and so on. We will have high-bandwidth connections to the Internet at all times. We will have eyeglasses for the sighted that display images directly in our retina: contact lenses for full-immersion virtual reality.

I have a prototype, a device allowing me to teleport my image in three dimensions to other locations from my office. I gave a speech to people in Vienna, Austria. It looked to the audience like I was present in three dimensions. People who did not know what was going on thought I was there.

By 2010, we all will be able to do this routinely—full-immersion virtual reality.

Besides teleportation, we will have relatively powerful (but not human level) artificial intelligence (AI) on web sites—artificial personalities such as the avatar-like Ramona, who greats visitors and answers questions at the KurzweilAI.net web site.
