There is a LOT of AI literature out there. Amazon.com has over 7000 AI non-fiction books in their catalogue. I've read a bunch of them (and have a bunch more on my reading list) but there are five that stand out to me as mandatory reading. The books I've listed here are by leading computer scientists and thinkers and really expanded my understanding and even my worldview. The first two get into technical details which really require reading the text, but the last three are well suited to the Audiobook format if you don't have the time to curl up on the couch with a paperback.
