Ontology of AdS/CFT classical on the bulk?

[SupremeFunky]

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.

No, the bulk is quantum too.

At low energies, the bulk is well approximated by classical gravity, but at high energies it is a string theory, which is quantum.
