If you are generally interested in the subject of intelligence, the brain, and intelligent machines, then run (don’t walk) to Amazon and pick up a copy of Jeff Hawkin’s (of Palm fame) new book On Intelligence.
You’ll only be sorry if you don’t! Seriously, its a seminal work destined to change forever the way we think about intelligence, the brain, and intelligent machines. From an amazon reviewer:
It is not very often that you encounter a book that alters, not simply what you think, but how you look at the world. On Intelligence is such a book. Jeff Hawkins develops a perspective on intelligence that makes sense of much of what I have discovered about learning over the past twenty years.
Audible.com also has it on audiobook so you can listen while you commute.
