How far ahead?

How far into the future might one think of looking?

For one idea, past the point at which familiar technologies are gone... or at least changed so drastically that they're no longer recognizable. Some technologies have been around for quite awhile, unchanged in basic form and function.

Although today's automobile may look drastically different in style from the early vehicles of the 1900 era, they essentially haven't changed that much. Four wheels, gas engine... But like technologies before and after, it's lifetime will be limited, or so I believe. What will replace it? A more advanced form of physical transport? Virtual presence? Teleportation?

I believe that there will come a time in the future at which the automobile, as well as many other familiar technologies, will not only be gone, but forgotten. And the only place to see one will be in a museum of ancient artifacts. That's a time I want to visit!
