I'm not a physicist (computer science background), but always was fascinated with the concept of entanglement. As many, the first intuition I had was - well, the two particles share some knowledge from the get go, so no matter how far you hold them, they still behave as one unit. I understand that this is called the hidden variables theory and that is generally refuted by Bell's theorem, and later in experiments.
Part 1 of the question
I understand that a recent "no loopholes" experiment in 2015  "proved" Bell's theorem (e.g. that the hidden variable theory can't explain / predict all entanglement situations)
Is there a good non physicist resource that explains how that experiment disproves this?
Part 2 of the question
Here is my computer science laymen question, I'm sure there is a basic flaw in this thought experiment but I'm not sure what it is. Let's say I have 2 RSA tokens created together with the same seed value and same random number generator, until I press the button, I have no clue what value it will show, but if I press the buttons on both tokens, no matter how far they are, they will all produce the same number, this is not a surprising fact and no need to perform an experiment as it's well known (actually no need of two tokens, the fact that the server and the token have the same seed and generate the same number is enough)
I understand that a single quantum particle has no way of holding all the complexity of a chip, the best scientist are working hard just to get one stable qbit, and this is just a very ridiculous and theoretical thought experience, but let's say it was possible to minimize RSA tokens to the quantum level, ant man style, (sorry for causing some of you to cringe) - what in that 2015 experiment has that debunks a "hidden RSA token style variables" theory? What in Bell's theorem (I tried to read it, I don't have enough background in physics to even make it past the first paragraph) negates a hidden deterministic pseudo-random number generator like mechanism?
What are the holes in the "RSA token hidden variable" idea? I'm sure others came up with this analogy, can you help me find the source? And is there a good source that refutes it?
Part 3 of the question
Bell was quoted saying:
"There is a way to escape the inference of superluminal speeds and spooky action at a distance. But it involves absolute determinism in the universe, the complete absence of free will."
 about super-determinism is exactly that RSA token explanation?
If so, I don't get it, the fact we have deterministic RSA tokens doesn't imply we have no free will, it just implies that the RSA has a pseudo-random number generator, it doesn't negate the fact our brains might have "true" randomness, so can't there be a coesistence of determinism in quantum entanglement but no determinism in our own mind? why are they necessarily related?
