Robopocalypse, by Daniel H. Wilson
Okay, let’s get this out of the way up front: In no no way is Robopocalypse of anything like the caliber of Our Final Invention or Superintelligence. Though written by an author who holds a PhD in robotics from Carnegie Mellon, this is an adventure novel. It explores some interesting aspects of a AI vs. humanity conflict, but it’s basically constructed in a way that’s very much mano a mano, …

Their geologist kindly showed us around and allowed us to visit his history-laden office. I have no idea where this sample originated, but it was the only fold I saw in the place, nestled between sepia-toned photographs and old lanterns and rusty picks. I wonder what …

A conversation with James Barrat
Yesterday I reviewed Our Final Invention, an accessible and provocative book about the development of artificial intelligence (AI) and the various ways it might represent a threat to some or all of the human species, all other forms of life on Earth, and (astonishingly) potentially even the very substance of the planet we dwell on (!). I strongly recommend everyone read it. Today, I’m please to present a discussion with …

Our Final Invention, by James Barrat
I am concerned about artificial general intelligence (AGI) and its likely rapid successor, artificial superintelligence (ASI). I have written here previously about that topic, after reading Nick Bostrom’s book Superintelligence. I have just finished another book on that topic, Our Final Invention, by James Barrat. I think it’s actually a better introduction to the topic than Bostrom, because it’s written in a more journalistic, less academic style. Most chapters read …

Let’s reminisce back to the Walls Boundary Fault on the Ollaberry Peninsula of Shetland today. Here’s a 3D model to go along with the ones I posted last time: It’s a little ragged, but so am I at the end of the workweek! Happy Friday. Have fun spinning this thing.
