“Fooling around with alternating current is just a waste of time. Nobodywill use it, ever.” - Thomas Edison, 1889
“The more important fundamental laws and facts of physical science haveall been discovered, and these are now so firmly established that thepossibility of their ever being supplanted in consequence of newdiscoveries is exceedingly remote…. Our future discoveries must belooked for in the sixth place of decimals.” - physicist Albert. A.Michelson, 1894
“It is apparent to me that the possibilities of the aeroplane, which twoor three years ago were thought to hold the solution to the [flyingmachine] problem, have been exhausted, and that we must turn elsewhere.”- Thomas Edison, 1895
“The demonstration that no possible combination of known substances, knownforms of machinery, and known forms of force can be united in apracticable machine by which men shall fly for long distances through theair, seems to the writer as complete as it is possible for thedemonstration of any physical fact to be.” - astronomer S. Newcomb, 1906
“Airplanes are interesting toys but of no military value.” - MarechalFerdinand Foch, Professor of Strategy, Ecole Superieure de Guerre, 1911

“The wireless music box has no imaginable commercial value. Whowould pay for a message sent to nobody in particular?” - DavidSarnoff’s associates in response to his urgings for investment in theradio in the 1920s.

“There is not the slightest indication that nuclear energy will ever beobtainable. It would mean that the atom would have to be shattered atwill.” — Albert Einstein, 1932
“The energy produced by the atom is a very poor kind of thing. Anyone whoexpects a source of power from the transformation of these atoms istalking moonshine” - Ernst Rutherford, 1933
“The whole procedure [of shooting rockets into space]…presentsdifficulties of so fundamental a nature, that we are forced to dismiss thenotion as essentially impracticable, in spite of the author’s insistentappeal to put aside prejudice and to recollect the supposed impossibilityof heavier-than-air flight before it was actually accomplished.” Richardvan der Riet Wooley, British astronomer, reviewing P.E. Cleator’s “Rocketsin Space”, Nature, March 14, 1936

“There is no reason anyone would want a computer in their home.” - KenOlson, president, chairman and founder of Digital Equipment Corp.,1977
Of course, there are many good skeptics, and good things to be skeptical about (in fact. I am willing to say that most new ideas are not completely valid, if at all.) Many will be surprised to find many great thinkers and scientists listed above (Thomas Edison, Jefferson, Einstein); just shows us that bad skepticism is not only the purview of the unthinking and unimaginative (The fact that these men where wrong in these instances didn’t take away from their virtues, by the way. In fact, some quotes above, even though they are wrong, are ligitimate thoughts somewhat taken out of context.)
By the way, I found all these quotes at Accelerating Future.
