Von Neumann was a polymath. He did research in quantum analysis and also invented the computer as we know it (von Neumann architecture).
For those who don't know, quantum theory describes all physics that deal with constantly quantifiable (small) amounts. While the big Universe seems chaotic and analogous where all measurements seem continuous (uninterrupted, without bumps) at any scale, the small Universe if you want it is made of discrete values and events. From molecule down, everything, has discrete life (predefined size and mass and (half) lifetime) and associated predefined values; (charge, mass, spin, etc..). If you smash one particle you would only get more particles in one precise, invariable, predictable event, but not random dust or anything. Think of it as grains (quantum) vs milk (classic).Here comes Stephen Hawking, that most people heard about, from his grim predictions about humankind future, but not knowing nothing about his work. One of his enunciations (if not the only major one) was the so called black hole paradox.
Quantum theory states that information cannot be destroyed in this universe. That is for every tiny event that happens there should be some leftovers from which we can figure the initial state of that system.
It is, in a way, an analogy or maybe even a continuation to the principle of conservation of energy and matter in classics.
However Hawking first said when something gets into a black hole it seems all information about that (sub)system is lost.
(How about mirroring events through quantum entanglement? What happens if a particle entangled with another enters a black hole and the other one not? Could entanglement happen more often than we know it and have something to do with transmitting or mirroring information, the meaning of the information itself or maybe even our conscience?) (Could all particles in the Universe be entangled?)
Hawking then comes with this theory stating that black holes can release a form of (thermal) radiation called of course Hawking radiation that may contain information about the things absorbed by the black hole, putting an end to his own paradox. But i believe there will be a long time, maybe an infinity (is infinite possible in quantum? is a numeric infinite really infinite since it is made of numeric values) until we will be able to know what it is (thermal means photons, right? not even light, right?) and how to measure it.
I can think of another way in which information can escape from a black hole and that is after the completion of a cycle big bang followed by a big crunch of the Universe when eventually all black holes reunite and then explode back giving birth to the new one. Maybe this is the way the collective or possibly a unique individual universal intelligence reunites with self and then because of much boredoom starts to agitate and releases self in a new equally complex living Universe. (Will we meet all there? Maybe, but only if we get in a black hole alive with all our memories still intact within the synapses of our neurons or maybe all emanate at death a form of Hawking radiation).
And here is another paradox. Let's say we have a RAM (Random Access, or read-write type of Memory) computer bit or better a few (a register) of the flash type that can memorize a certain information (a number) by means of trapping a few electrons for each bit, and let' say that number that is never accessed (read) or known.
We all know that we can reuse that register to store other information. So what happens to the previous information stored in that registry? Some will argue they will be leftover electrons or whatever down the drain, but those are melting in the analogous chaos of the thermal agitation inside connectors whatever (and would not exist other than heat since we can't observe them individually anyways once they left their quantum trap).
(From the information written in the previous paragraph, we may also deduce that all computers are quantum, obviously because they deal with quantum state information or using a (quantifiable) number of electrons per bit).
But from the point of view of the user of that system, the information that was never read was lost and/or destroyed period.
So John Neumann must have known this as it is (probably) the first thing that comes to the mind of a polymath who worked in both fields after examining the way RAM memory registers behave. Though flash memory did not exist during his days, (but maybe was predicted) FETs that use around 10.000 electrons per bit or capacitors existed etc.. According to google, he never said anything about it, like Leo Szilard did (maybe he didn't want to start another recession followed by a war, though the world was kinda tired of those at that time).
I wouldn't have bothered to mingle in this virtual scientific space with all these illustrious minds (von Neumann, Hawking, Szilard, Masuoka etc.) if i would not be continuously pissed by bits of information that appear in media that seem to try to cancel or delete the ones i just put (in the same virtual space or registry) and i keep asking myself if there's not some "secret" theory behind it. Wouldn't be the first time when they apply quantum theory to society (though social beings are obviously not quantum, their thoughts or information stored in their mind always is).
Another more "active" way they can destroy information with no possibility of retrieval from the stating enunciation is a lie.
Humans are probably the only beings in Universe capable of lying (destroying information, replacing with something else) and thus causing artificial modification of natural social causal chains (altering the course of Universe at will, rebuilding?). Truth can be reestablished only using information from different causal chains that are related or reflecting the one that have been directly altered but is usually inefficient and it is impossible to fix subsequent causal chains that have already been altered by a lie as not all may be reached by the consequences of correction. (A fool can throw a stone in a pond that 100 wise men can not get out.).
After thoughts.
I think is safe to assume that Hawking radiation occurs at the event horizon level of the black hole, where elementary forces from within are strong enough to deconstruct every piece of matter that enters the black hole and only when some "useful" information about the arrangement of matter is destroyed and at that moment only. That leads to the possible generalization that every time information is destroyed (in this case about arrangement of matter entering the black hole) this radiation occurs.

By generalizing we deduct that any type of destruction of information is accompanied by such radiation, like in the case of someone's death or when someone decides to lie or when a Newman architecture type of computer registry is emptied of information etc..
So i can state that every time a RAM memory that was written is being powered down, Hawking radiation is emitted.
Talking about black holes and Hawking radiation an idea came to me. Most scientists and journalists of course these days agree that the Universe is finite and ever expanding, which expansion one day or eon may stop and reverse. However there is one thing i don't understand. Radiation, like Hawking radiation and generally radiation may escape the boundary of the Universe upsetting the matter/energy balance of the initial big bang heading to a big crunch (or maybe the edges of the Universe expand too fast for that to happen?).
Another thing is if Hawking radiation can escape a black hole, will it probably escape the big crunch as well, possibly preserving our souls for the next Universe, like Scientology says? etc..
I could write much more on this but i keep some ideas to myself as i'm not being paid for this, this sample, a few others is just enough to show how far behind we are after more than a century of media and lies and discretionary intentionally misdirected grants.
