Abstract question here, but does this paper prove we're not living in a simulation, versus proving that at our current amount of knowledge, we can't prove if we're in one, or not?
The bigger question, of course, would be how many simulations deep we are at, and how long until we make our own.
I'd say it proves that we are not living in a simulation that
a) runs in a universe that has the same computational constraints as ours and b) simulates quantum effects faithfully at macroscopic levels
