This more of a personal attack than a thoughtful review. No content.

More precisely, simple rules can have emergence. Wolfram's most common example is simple cellular automata. Cellular automata do not need to be simple. Other rules like Turing machines can have emergence.

I read another Wolfram blog post where he answered those criticisms. http://blog.stephenwolfram.com/2012/05/living-a-paradigm-shi...

I don't think Bell's theorem raises a problem in either LQG and CDT because they have the traditional quantum theory built into them. They are not deterministic theories like Wolfram's. Bell's theorem discounts the possibility of quantum (as it is observed) if there were no long range connections defying locality.

Bell's theorem assumes that spacetime is locally Euclidean so it is not relevant when there are networks and rules that allow for causal connections that appear to be an observer at a distance.
