There is nothing fundamentally different between running a classical simulation on a classical computer and running a quantum simulation on a quantum computer - both are just a simulation.

So claiming that this quantum simulation of a SYK model of a wormhole is in some way actually related to a wormhole is exactly like claiming that the circuits of a supercomputer used for simulating rainfall patterns are getting wet.

Not to mention, the model being used is a toy model of a type of space-time that is not at all like our own spacetime - it's not even a simulation of a physical model, it's just a mathematical model that we already know doesn't describe the physical world.
