Just because I'm marginally knowledgeable about such things, let me
pipe in. I'm pretty sure that's an incorrect interpretation. Bell's
inequality, if true, says that quantum mechanics is either "true
random" /or/ "non-local". It's possible to have a determinmalistic
system of equations that can produce observed quantum mechanics if you
allow FTL interactions. Not necessarily FTL information flow, but some
sort of hidden variable system which is non-local.

IIRC, there's also some discussion of whether Bell's inequality are
true. I'm not the most versed on it, but I think that the evidence for
Bell's inequality is less than foolproof.

I'm sure wiki can do a better job of explaining it, so I direct any
more questions to there.
