Important to remember, especially if you're practicing physics or engineering in any form: models are not the real world. You're (kind of) right about the (typical interpretation of) the models we use for entanglement, but open questions in this field include things like whether a wavefunction is "real" or just a mathematical tool that seems to get the right results at the length/energy scales we look at.

tl;dr: Just because you have an equation doesn't mean that equation corresponds to anything real. This is the same mistake people make all the time with statistics -- the math is easy, finding the right math to use can be very hard.

No, these are not open questions. QIT answers all of them. It describes exactly how classical reality emerges from the quantum wave function, and hence settles the question of whether or not it is "real". The answer is: the question of whether or not the wave function is "real" is based on the false a assumption that "real" is a binary predicate. It isn't. Whatever the mathematics of the wave function describes does indeed exist, but it exists in a separate ontological category from classical reality.
