This really looks interesting, I really like its simplicity. However it feels like that the arguments should either support the given statement or its converse. I think there should be other options too. As a physicist I would argue that the very statement "The universe is a simulation." is non-falsifiable, therefore it's not something we should argue about. There could be other problems with statements too, like "the GPL is freer than the BSD licence" where there is no consensus on the definition of free.
It would be nice if one could source other statements, it could integrate with it quite well.
