Computer technology has eveolved at a pace that outstrips our ability to use it and make it stable, but not fast enough to keep up with our dreams.
Example - today's computers still do the same magical tasks of adding, subtracting, retriving information (data, pictures, sound) and recording the inputs from microphones, camera's etc that they did 15 years ago.
Computers did some of this 25 years ago but on a much smaller scale.
So far computers still can not pass a Turing test and think or dream like a human.
