You are making an unscientific criticism.
Wolfram's claim is that Cellukar Automata can provide as good or better mathematical model of the universe than current current theories, by commonly appreciated metrics such as "pasimony of theory" (Occam's Razor). He's not making claims about metaphysical truth.
Well, the question 'is this Wolfram guy doing science' is as such not a scientific question. And the answer is a resounding 'no'.
