In 1966 President David O. McKay prophesied scientific discoveries that “stagger the imagination” would make possible the preaching of the gospel to every kindred, tongue, and people. And further:

“Discoveries latent with such potent power, either for the blessing or the destruction of human beings, as to make man’s responsibility in controlling them the most gigantic ever placed in human hands. … This age is fraught with limitless perils, as well as untold possibilities” (in Conference Report, Oct. 1966, 4).
