Consider the following model.
Put a lattice of N electrical nodes on a sphere. The lattice doesn't have to be perfectly regular. Each node is connected to others by copper wires that run through the interior of the sphere. The wires do not interfere with each other.
In some initial state...
Is it true in AdS/CFT the ontology on the boundary is quantum (whatever that may be), and the ontology in the bulk is classical?
If that were true it would be a new "interpretation" of quantum mechanics.
