Oh, one more thing. This whole shebang which I was writing about shouldn’t be confused with so-called pseudorandom numbers, i.e. those generated by a computer on some deterministic basis instead of some abstract ‘truly’ random ones (one could also debate what that is), but with essentially the same properties in terms of distribution for practical purposes.
What I was talking about is explicitly not-quite-random numbers used deliberately instead of (pseudo)random ones, as elaborated above.
