By having global hidden variables it may be possible to get something like quantum mechanics without any true indeterminsmThis would however result in there not being any true passage of time since the future would already be determined, from this alone we can rule out any attempt at a unified theory in advance unless it's fundamentally deterministic.Thus we can conclude that the project Stephen Wolfram is doing now will end in failure:There are of course plenty of red flags regarding his project, it's very unlikely that he will actually be able to get the physics we can observe and thus it will probably be relegated to being a mathematical curiousity like so many previous failed unification attempts, the Kaluza-Klein model also looked promosing initially but turned out to be "unphysical" (not real).
