Oha! Danke für die kritische Überprüfung. Ich lasse mich gerne eines Besseren belehren. Ich habe soeben den Quote Investigator gefunden, dort wird auf die erste Quelle verwiesen:
The earliest evidence known to QI appeared in 1963 in the book “Inventing the Future” written by Dennis Gabor who was later awarded a Nobel Prize in Physics for his work in holography. Boldface has been added to the following passage and some excerpts further below:
"We are still the masters of our fate. Rational thinking, even assisted by any conceivable electronic computors, cannot predict the future. All it can do is to map out the probability space as it appears at the present and which will be different tomorrow when one of the infinity of possible states will have materialized. Technological and social inventions are broadening this probability space all the time; it is now incomparably larger than it was before the industrial revolution—for good or for evil.
The future cannot be predicted, but futures can be invented. It was man’s ability to invent which has made human society what it is. The mental processes of inventions are still mysterious. They are rational but not logical, that is to say, not deductive.
Ich stelle also richtig: die erste Aufzeichnung des Zitats „Der beste Weg um deine Zukunft vorherzusagen, ist, sie zu erschaffen.“ stammt von Nobelpreisträger Dennis Gabor in seinem Buch “Inventing the Future” (1963).
