Classical spacetime emerges from string theory through holographic dualities
The retrieval evidence strongly supports the idea that classical spacetime geometry emerges from underlying quantum systems through holographic dualities, such as the AdS/CFT correspondence and tensor network models.
Papers [1] and [7] directly address holographic dualities, AdS/CFT bulk/boundary correspondences, tensor networks, and matrix quantum mechanics connected to string theory where spacetime geometry emerges from boundary or entanglement data.

Paper [1] discusses holographic quantum error-correcting codes as models of AdS/CFT bulk/boundary dualities, where bulk spacetime geometry emerges from boundary degrees of freedom.
