Yes, I'm on board. The point is that as far as we understand currently there's no "good reason" for spacetime to be discretized, save for it being run in someone else's computer. That by no means indicates that it is in a computer. Indeed, as far as we know, spacetime is not a grid! So if the hypothesis is: computer we are alleged to live in is any way like computers we ourselves build (eg. finite memory, finite processing speed, discrete, etc.), this paper is a step towards falsifying that hypothesis, not confirming it!
