It makes a tiny bit of sense to me.
"If we use [unstated first principles] to estimate what energy density should be, it's about 10^94 g/cm^3.
If we use the information content at the Planck scale, it's pretty close -- about 10^90 g/cm^3.
But we actually observe an information density of about 10^-27 g/cm^3.
And if we decrease the resolution from Planck scale voxels to 10 km^3 voxels, we get an information density that equates to 10^-27 g/cm^3.
This is evidence that we are living in a simulation, and the programmers aren't running the universe at Planck scale voxels, but only star sized voxels."
A large mountain of salt needs to be taken with this argument, but it does make sense -- as an argument.
