AUTHOR:         George Bernard Shaw (1856–1950)
QUOTATION: You see things; and you say “Why?” But I dream things that never were; and I say “Why not?” ATTRIBUTION: GEORGE BERNARD SHAW, Back to Methuselah, act I, Selected Plays with Prefaces, vol. 2, p. 7 (1949). The serpent says these words to Eve.

President John F. Kennedy quoted these words in his address to the Irish Parliament, Dublin, June 28, 1963.—Public Papers of the Presidents of the United States: John F. Kennedy, 1963, p. 537.

Senator Robert F. Kennedy used a similar quotation as a theme of his 1968 campaign for the presidential nomination: “Some men see things as they are and say, why; I dream things that never were and say, why not.” Senator Edward M. Kennedy quoted these words of Robert Kennedy’s in his eulogy for his brother in 1968.—The New York Times, June 9, 1968, p. 56.

Note, with emphasis, the second of those quotes, in that last set of quotes.

And, remember - the breaking of the enigma code, was regarded as impossible, and, without the trying to break the code, and, the actions of Alan Turing and Joan Clark and their team, we would not have these devices named electronic computers, but, computers would still be the people who were the women in the movie "Hidden Figures". And, wasn't what was achieved in that movie - launching a rocket into space, and, later, travelling to the moon, all regarded as impossible?

Read all of the quotes above, and, consider...

And, remember, in the first series of Star Trek, they had talking computers and other things that computers were able to accomplish, way before humans got such achievements into practice.
