Futurist Vernor Vinge on the Looming Singularity:

[I]n the relatively near future, we will be able to use technology in order to create, or become, creatures of superhuman intelligence. As technological changes go, this is qualitatively different from the big events in the past. You could explain fire or agriculture to somebody who lived before those technologies were invented. But after the singularity—it would be like trying to explain this interview to a goldfish.
