From inside a simulation, it's impossible to tell how fast the simulation is running because you have no external time reference. The visible universe as we know it could be running at a time dilation of of 10^100:1 and it would look exactly the same to us.

True, but orthogonal to the argument. Elon's pro-simulation argument is fundamentally grounded in our reality ("video games have progressed a lot and there are lots of video game consoles, so eventually we could run the types of simulations postulated"), and my argument is refuting that ("video games will never be good enough to run those types of simulations")
