Query: Disappointing!

I initially was so very excited to have this book! I informed my spouse that it would probably take me a year to digest it. Unfortunately, a couple of nights of reading revealed it to be a sham. If it wasn't Wolfram writing, Iwould think it was prepared by a fraud who was trying to convince us it was of great foundational worth. It isn't. The poorest scientific reading I have encountered.
