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 &quot;real&quot;.  The answer is: the question of whether or not the wave function is &quot;real&quot; is based on the false a assumption that &quot;real&quot; is a binary predicate.  It isn&#x27;t.  Whatever the mathematics of the wave function describes does indeed exist, but it exists in a separate ontological category from classical reality.<p>See blog.rongarret.info&#x2F;2015&#x2F;02&#x2F;31-flavors-of-ontology.html for more details.
