Hey Comrade . . . here's some "substantive criticism" of the book . . .
It's absolutely impossible to understand . . . heck even read . . . without a guiding hand.
You find me ONE person who has ever been able to get the book without the help of an AI or Homer Kelley directly.
That book should sold as a PDF file that is capable of being searched. And should come with multimedia to demonstrate the concepts. Mr. Kelley did the best with the technology he had . . . a freakin' typewriter (not even a word processor).
But we have the techology now to basically make the book accessable to the "masses." Will it ever happen???
