“I have traveled the length and breadth of this country, and have talked with the best people in business administration. I can assure you on the highest authority that data processing is a fad and won't last out the year.”
— Editor in charge of business books at Prentice-Hall publishers, responding to Karl V. Karlstrom (a junior editor who had recommended a manuscript on the new science of data processing), c. 1957

“There is no reason for any individual to have a computer in their home.”
— Ken Olson, President of DEC, World Future Society Convention, 1977

“Heavier than air flying machines are impossible.”
— Lord Kelvin, President, Royal Society, c. 1895

“As a method of sending a missile to the higher, and even to the highest parts of the earth's atmospheric envelope, Professor Goddard's rocket is a practicable and therefore promising device. It is when one considers the multiple-charge rocket as a traveler to the moon that one begins to doubt ... for after the rocket quits our air and really starts on its journey, its flight would be neither accelerated nor maintained by the explosion of the charges it then might have left. Professor Goddard, with his "chair" in Clark College and countenancing of the Smithsonian Institution, does not know the relation of action to re-action, and of the need to have something better than a vacuum against which to react ... Of course he only seems to lack the knowledge ladled out daily in high schools.”
— ‘A Severe Strain on the Credulity’, New York Times Editorial, 1920

“Where a calculator on the ENIAC is equipped with 18,000 vacuum tubes and weights 30 tons, computers in the future may have only 1,000 vacuum tubes and perhaps weight 1 1/2 tons.”
— Popular Mechanics, March 1949

“What the hell is it good for?”
— Robert Lloyd (engineer of the Advanced Computing Systems Division of IBM), to colleagues who insisted that the microprocessor was the wave of the future, c. 1968

“Adding sound to movies would be like putting lipstick on the Venus de Milo.”
— actress Mary Pickford, 1925
