This reads like a map of the meanings of and approaches to AI. As someone with a pretty rookie, enthusiast-only contact with the field, "AI" to me was sometimes simple enemies on video games, sometimes digital agents or assistants, sometimes another name for search algorythms and sometimes the big future singularity that could either save us all or go Skynet on us. There's the famous divide between "weak" and "strong" AI, or AI vs. the so-called "ASI", but, as this book shows, that's not actually that helpful. Artificial Intelligence is a very real part of our world, and this book - which introduces different fields of study that sprung from or gained a lot from AI research - tries to explain it all, clearing up the distinctions between the multiple definitions of intelligence, conscience, "robot" and more, surprisingly keeping itself short in the process. Oh, but it also recommends additional reading in every one of the subjects it mentions. The author doesn't shy away from expressing his enthusiasm for the field, as much as his disappointment with the academic infighting and lack of integration, but makes an effort to keep things facual, instead of speculative, until near the very end. I loved it. It IS from 2003, though, so I'm sure a lot more already happened, but now I feel I know what to look for.
