The Quantum Extrema Surface Prescription

Quantum extremo surface is a real physical surface, aneas it lives in sae time. How does this quantum extreme surface us understand the decrease and entanglement of the black hole? We don't know how to port over those insights from the quantum extremo surface prescription into the same model that hawking was working with. Given how quickly things have in the past couple of years, i expect that our ignorance of this is not going to last much longer.
