10 different predictions that were WRONG

1. The New York Times said that "A rocket will never be able to leave the Earth's atmosphere." This is a prime example of an incorrect prediction because we now have put men on the moon and are trying to send a manned mission to Mars.
2. The Quarterly Review said that " What can be more palpably absurd than the prospect held out of locomotives traveling twice as fast as stagecoaches?" This was at the start of the Industrial Revolution so it makes sense that they were confused but now it is nearly impossible to find a stagecoach.
3. Steve Ballmer said "There's no chance that the iPhone is going to get any significant market share." Look at the market today, the iPhone is in the lead by quite a margin and is offered by nearly every carrier despite it's lack of durability.
4. C.P. Scott said " Television? The word is half Latin and half Greek. No good can come of it." Funny quote but clearly some good has come of it because Americans are hooked to it. From television to movies, people love getting their fix of altered reality. 
5. John Langford said "Democracy will be dead by 1950." To this day there are many democracies and dictators are slowly on their way out of power because of the systemic issue of the lower classes rising up demanding rights like their neighbors. 
6. A Boston newspaper said "Well-informed people know that it is impossible to transmit the human voice over wires as may be done with dots and dashes of Morse code, and that, were it possible to do so, the thing would be of no practical value." Essentially, the paper couldn't image human voice being carried through wires though now we have telephones, radio, and television.
7. Robert Millikan said "No "scientific bad boy" ever will be able to blow up the world by releasing atomic energy." Now we see that atomic bombs were deployed during the second World War in Japan. Atomic bombs are real threats because of the massive human casualties.
8. Guglielmo Marconi, a pioneer of radio, stated "The coming of the wireless era will make war impossible, because it will make war ridiculous." However, it made war even more dangerous with people able to plan out their attacks from far away and make it a logistics nightmare. 
9. A naval officer stated that "I do not myself think that any civilized nation will torpedo unarmed and defenceless merchant ships." However, this happened during World War II as well as not just torpedo but the atom bomb was deployed on Japanese civilians.
10. Albert Michelson said "The more important fundamental laws and facts of physical science have all been discovered" in 1903. Now we have made many advances in physical science like the discovery that space is expanding between galaxies etc.
