Regarding interpretations of quantum mechanics, the interpretation is unimportant -- the math is the same is the same is the same. If you want to think about particles as being controlled by fairies who are locked up in hidden dimensions, that's kinky and totally fine -- as long as we use the same math, I don't really care.
If your fairies end up predicting new phenomenon that exist, which are not predicted by the Born/Copenhagen interpretations, sign me up -- I'll go to wonderland. Until then, let's leave interpretations out of our conversation.
My point in bringing up boson gasses and neural networks was to show that two vastly different systems at different scales can both exhibit self-organization described by similar mathematics. I am not saying those systems are equivalent, but I am saying that self-organization is a very versatile term and that throwing it around with no context warrants more content.
