It’s easier to think about the fate of specific gizmos, especially ones that are well woven into the fabric of modern life, such as the automobile. This one sounds like you could plug it into your iPad:
Car of the Future
The car of the future won’t leave anything to be done by man power. In two or three years foot brakes will be things of the past except on cheap cars. Why should a man exert muscle to stop a car any more than to start it? What’s that great brute of an engine idling under the hood for? Now, jump three jumps more. If the engine starts and lights and pumps and stops itself, why shouldn’t it steer the car? Revolutionary? Nonsense!...The car of the future will have no such thing as a “driver’s seat.” All the seats in the car save the rear one will be moveable. Driving will be done from a small control board, which can be held in the lap. It will be connected to the mechanism by a flexible electric cable. A small finger lever, not a wheel, will guide the car.

Predictions can be quite bizarre. Perhaps that’s a value judgment. In this case, it starts out fine then really does get bizarre:
The next 75 Years
The construction of the North River Bridge, now assured, will be followed ultimately by the building of a few other long-span bridges of equal or greater magnitude, such, for instance as a 4,000-5,000-foot span across the waters of the Golden Gate at San Francisco.... Where bridging is impossible, resort will be had to tunnelling, and it is probable that the next decade will see the completion of the 21-mile Channel tunnel, to be followed by one between Scotland and Ireland....
Okay, we get it. Bigger bridges, longer tunnels, faster airplanes, all standard stuff. Any twit can figure that out. But here’s where this particular prediction goes off the rails:
....But the fact can hardly be escaped that there is a growing fund of well authenticated phenomena which are explained by no natural law yet formulated, and which seem to require that we postulate the existence of some force operated, consciously or unconsciously, by the human brain. Nobody, for instance, can deny the phenomenon of hypnosis. No careful person is going to deny categorically the accumulating evidence that there really is some sort of communication between individuals widely separated in space, to which the general name of mindreading or thought-transferance or telepathy has been provisionally applied.
We think we may, without being accused of having fallen victim to the post-war hysteria, suggest that when all cases of fraud and hypnosis have been ruled out, there is a residuum of material demonstrations of an as yet intangible force--things to which the hateful names of spirit-rapping, table-tipping, levitation, etc., must be applied until we get a more respectable term to take their collective place.
On all these grounds we are inclined to predict that there exists a force, operated through action of the human brain, that is capable of producing sensible effects and effects upon another brain. The science of tomorrow will tell us what this force is and will give us a control over it which may turn out to be as complete as our control over the electric impulses which today we shoot through the ether in utter defiance of all the experiment and all the knowledge and all the common sense of a generation ago.
