Hmm, well that's okay, I've got more where that came from:

• Heavier-than-air flying machines are impossible. - Lord Kelvin, president, Royal Society, 1895
• I think there is a world market for maybe five computers. - Thomas Watson, chairman of IBM, 1943
• There is no reason for any individual to have a computer in their home. - Ken Olsen, president, chairman and founder of Digital Equipment Corp., 1977
• The telephone has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us. - Western Union internal memo, 1876
• Airplanes are interesting toys but of no military value. - Marshal Ferdinand Foch, French commander of Allied forces during the closing months of World War I, 1918
• The wireless music box has no imaginable commercial value. Who would pay for a message sent to nobody in particular? - David Sarnoff's associates, in response to his urgings for investment in radio in the 1920's
• Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools. - New York Times editorial about Robert Goddard's revolutionary rocket work, 1921
• Who the hell wants to hear actors talk? - Harry M. Warner, Warner Brothers, 1927

Strike them down and others will take their place! ;-)
