> Quantum mechanics can't seem to be imitable by a local classical computer. So is this a fatal flaw in Wolfram's "new kind of science" based on cellular autom

  One of the many flaws. The other is that his cellular automata model violates special relativity.

  As far as I'm aware, Wolfram doesn't think cellular automata underpin our physical universe; they're just a very simple form of universal computation, which makes them interesting to explore. He thinks the Universe is more like a graph of nodes and edges, with particles, interactions, spacetime, etc. emerging from the rewriting of simple patterns in the network http://blog.stephenwolfram.com/2015/12/what-is-spacetime-really/ http://blog.stephenwolfram.com/2015/12/what-is-spacetime-rea...

  I'm not sure if this is meant as an update or merely my misinterpretation of a brief passage, but while NKS book's chapter on principle of computational equivalence talked about the principle applying to any process of any kind both natural and artificial, the current definition of the principle on Wolfram's mathworld only defines as applying to systems found in the natural world. https://twitter.com/_nict_/status/727513301274529792 https://twitter.com/_nict_/status/727513301274529792
