You insist that there is something a machine cannot do. If you tell me precisely what it is a machine cannot do, then I can always make a machine which will do just that.

Anyone who attempts to generate random numbers by deterministic means is, of course, living in a state of sin.
Interpretation
What this quote means
Generating randomness through predictable processes is inherently flawed.
This quote by John Von Neumann highlights the paradox of trying to create randomness using deterministic methods. It suggests that true randomness cannot be achieved through logical or predictable algorithms, implying that such attempts are misguided, akin to a moral failing in the pursuit of genuine randomness.

All quotes βThe sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work-that is, correctly to describe phenomena from a reasonably wide area.

Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin. For, as has been pointed out several times, there is no such thing as a random number - there are only methods to produce random numbers, and a strict arithmetic procedure of course is not such a method.

It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years.

Technological possibilities are irresistible to man. If man can go to the moon, he will. If he can control the climate, he will.

I would like to make a confession which may seem immoral: I do not believe absolutely in Hilbert space any more.

My study is NOT as a climatologist, but from a completely different perspective in_x000D_ which I am an expert β¦ For decades, as a professional experimental test engineer, I have analyzed experimental data and watched others massage and present data. I became a cynic; My conclusion - 'if someone is aggressively selling a technical product who's merits are dependent on complex experimental data, he is likely lying'. That is true whether the product is an airplane or a Carbon Credit.
