I bought this as an audiobook on iTunes for a car trip or something, back in ~2006. It made a huge impact because its theories are so simple and easy to understand that, if you are even a novice programmer, you can probably imagine how you'd go about implementing such a brain. Especially if you find the original white papers and read them too, as they practically include the source code if I recall (I've got them printed and bound on a shelf somewhere).

While I was in grad school, I spent several weekends tinkering with my own implementation of a very simple HTM to process shapes in Go (the game). It never did much in the way of playing Go, and I stopped messing with it after something else more practical got in the way, but I'd love to dust off that code and now seems like a great time to get back into it.

The narration on the audiobook is very high quality, and, for me at least, the ideas were quite accessible through audio. I highly recommend it if you're the type of person who might purchase such a book in paper and never get around to reading it (but you have time to kill in the car).

This is a fantastic book.

To quibble.

On Intelligence is a prescription for an intelligent system which Numenta's software is intended to fill. So On Intelligence would tell you the motivation for the system but not how the system works in any detail.
