All three volumes of the ebook Rationality: From AI to Zombies are complete and available for purchase on Castify. A big thanks to the narrator George Thomas. The total recording time is over 51 hours.
Five math-heavy essays in the second volume went unread because they didn't make for good listening. To read these the ebook can be downloaded on a "pay-what-you-want" basis from intelligence.org.
Thanks again to the original kickstarter backers, we wouldn't have been able to do this without you.
