This book is not to be read lightly it is very complicated and very hard to understand , if you like Escher and Gödel, this book tries to make there works seem it is symmetrical and ‘Recursive’. 

 It is a hard book to read and I don’t fully understand whole book, I think there maybe hidden messages in there for the real brainiacs. 

It talks about A.I and maths and systems, and a whole lot of stuff I don’t understand. Very philosophical.
