The fact that intelligent machines are possible raises many concerns. People feel threatened when their unique sensibilities are called into question. Hubert Dreyfess, a student of physics and later a Philosophy professor at MIT holds the position that humanlike intelligence cannot be imitated through symbolic representation. This tenet was in direct opposition of the rule-based efforts of Noam Chomsky's Transformational Grammar and David Marr's Theory of Vision, both of whom were at MIT the same time as Dreyfess. This non-fiction book is for the technological handicapped as well as technologically adept who are interested in Artificial Intelligence from its inception.
Hogan describes concepts in an easy and sometimes humorous manner.
I recommend this book to everyone who has faith in technology and a proclivity towards the ambitious endeavors of mankind. Hogan succeeds in inspiring his audience to think about the implications of Artificial Intelligence and therefore enabling them to draw their own conclusions.
