I was going to "review" this in prep for the Sunday Philosophers meeting, but I was enjoying looking it over again so much I decided to reread it once more!
A first-rate story that also make you think
UPDATE: Reread in 2020 for my SF and philosophy groups, only one month apart . It will be fun to see if and how the discussion varies between the two groups. It was just as good the second time around.
SF group 2020 bottom line: The standard practice in our group is to open with everyone giving a SHORT report on their impression of the book. We kick it off by having the first speaker be someone who highly disliked the book, followed by someone who loved it, and then go around the circle. We could find NO ONE who disliked the book, even a little. In our discussion later, of course there were some quibbles; no book is perfect. Some of the characters seemed a bit extreme, and many were skeptical that AI could advance so quickly or that Naomi could make her changes as easily as she appeared to do. But overall people enjoyed the book and agreed it provided good fodder for discussion in a group.
Sunday Philosophers bottom line: Everyone in the group liked this one, too. We talked quite a bit about the Three Laws and whether they could or should be used in AI as it becomes more autonomous and what such laws would look like. We also talked a bit about the concepts of consciousness and personhood as they are explored in the book. Everyone agreed it was a very thoughtful book. We DID talk about it as a NOVEL, too, though. I think it succeeds on both scores!
ORIGINAL REVIEW: It is the somewhat near future. Self-driving cars are on the road, but they are fairly new, expensive, and a bit controversial. Although they are safer than human-driven cars, it is still news when someone dies from an accident with a self-driving car, so a lot of attention is being given to making them even safer. Tyler and Brandon are grad students at the University of Pennsylvania, working on what they hope will be the start for their own entry into the field, mechanisms to help self-driving cars communicate with each other, to tell other cars of their own intentions and give warnings of things that the other cars may not be able to see. They round out their project team with two sisters, Abby and Naomi. Abby is an MBA student and provides the business management expertise, and Naomi is an introverted true geek, a computer science/ cognitive science major. A disastrous incident causes a total breakdown of Tyler and Brandon’s personal and professional relationships, and the former close friends become fierce competitors. That is ALL I will say about the story, and I would not have said this much if the publisher had not already done it in the book description, because I do not want to spoil any of the beautifully done surprises Walton has for the reader.
I recommended this book to my husband, who loves SF, and about halfway through he said he was really enjoying the book but it almost wasn’t science fiction. I told him to wait a bit and he would change his mind! First and foremost, this is a good story. The characters seem believable and think and react like people I might know. The story is full of surprises but is credible (once you accept the idea of a future where self-driving cars are on the road). Like the best SF, though, it is thoughtful about several areas. On the SF front, it extrapolates in a plausible way what we might expect with software “if this goes on.” It deals with philosophical questions like consciousness and intelligence and how we might determine if an entity is conscious, self-aware, sapient, intelligent. It faces ethical questions that WILL arise if/when we get self-driving cars, like how to decide who deserves the most protection. Who should my car protect, me or the little girl who just ran into the street after her ball? And who gets to choose the algorithm in my car, me or the carmaker or the government?
These kinds of issues have interested SF writers and readers for many years. Brandon and Naomi enjoy challenging each other with quotes or references to many classic SF works and authors, and clearly these have inspired Walton as well. I had read most of them but am now motivated to reread or to pick up on the ones I missed, and Walton clearly expects this, so he kindly provides a list of the SF references at the end of the book.
Walton uses the thinking of a number of prominent philosophers and other scholars as background for his philosophical explorations. He talks about classic situations like the Chinese Room problem and the trolley problem and the theories of people like Daniel Dennett and David Chalmers. He strikes a good balance in these discussions, fitting them into the story without doing a big “data dump” and giving enough information that I believe someone for whom this is new will understand the problems but not so much that someone who is familiar with it will get bored.
So Three Laws Lethal delivers a good story that kept me reading because I wanted to know what happens to these people…and it also made me think. I can’t ask for more than that.
