Here is a general thought about it. I think anyone who ever played with CA more seriously had a similar idea, but NKS took it a step further and tried to formalize it. It's an interesting read, with A LOT of bloat in the book. Actual book is damn huge, and IMO it could have easily been a book of ~300 pages at most. Aside from that, I think it's quite interesting and well worth a read, even if you're not into CA itself - that is, if you can navigate yourself around the bloat. I've read the book from a data compression/information complexity interest standpoint. So, I can't comment on it's pretensions over it's usefulness in all area of sciences.
