Before the invention of the atomic bomb

If we were to release the energy of atoms or discover some other way of developing cheap and unlimited power at any point of the globe this accomplishment, instead of being a blessing, might bring disaster to mankind in giving rise to dissension and anarchy which would ultimately result in the enthronement of the hated regime of force. The greatest good will come from technical improvements tending to unification and harmony.

Nikola Tesla (1856–1943)
Inventor, mechanical engineer, and electrical engineer
