Alasdair Wilkins at io9 has a very nice article about Asimov’s Robots, focusing on how obeying the Three Laws can still end up with killer robots running around loose. David Brin also put together an interesting post yesterday covering a number of different topics, including the SIGMA group, which had another gathering this past week in D.C.. Wish I had known about the book signing the authors did at Reiter’s Bookstore as part of that event ahead of time, it would have been fun to attend.
