Re: The embedded gear is often based on very low-power hardware
Anyone who quotes von Neumann on random numbers in a discussion of true1 physical RNGs is in a state of irrelevance.
1Or, if you believe in strict determinism, intractable physical RNGs. But if strict determinism is true, then you have no free will and thus no choice over whether to split hairs over what might constitute "true randomness", so either you're wrong in your belief or there's no point in reading this footnote. Of course, in the latter case, you have no choice of whether to read the footnote.
