I wish somebody on here could write a meaningful summary of this. I refuse to believe that Wolfram is a crank as some commenters seem to imply.

This post is almost pure unrelenting direct-marketing drivel, minus the call-to-action for your credit card at the end. All tell, no show. Instead of describing his theory, he describes the various exciting contortions that his face went through when he thought of it.
It is very, very hard to tell whether there is anything here. It looks as if he has taken a data structure so basic and flexible that it can represent anything you could ever think of, and then found to nobody's surprise but his own that it can represent all of known physics. Well, some other things that can represent all of known physics include: The alphabet? Math notation? Set Theory?
But I repeat: It is very, very hard to tell whether there is anything here. It is an avalanche of pictures of complicated-looking graphs, and breathless exposition that I fear does radiate crankiness. It appears to be about a million times more complicated than the physics we already have. If it isn't a million times more complicated, then he has done the worst job he could possible do of communicating it.
A relevant question to ask might be: What other leading theoretical physicists consider this a promising line of inquiry?
Sure, that’s a relevant question. It’s also a very obvious one, so consider answering it yourself. At the same time, Wolfram has always admitted he’s an outsider not so much in a victimized manner, but that (to me) he recognizes he still has work to do before the physicists start trying to integrate his work. There’s many applications of some of his ideas in a great many domains, especially those that can be abstracted by complex systems.
