Reddit mentions of A Legal Theory for Autonomous Artificial Agents

You didn't provide much information about what you hope to achieve in your learning. You call yourself a non-scientist who knows little about computers. If you have a goal of fully understanding the application of AI to law eventually, then you need to have more than a little knowledge of computers in general as a foundation for studying AI. In that case, you would begin your learning by studying to learn more about computers in general. Then, you would learn about how to program computers. Then, you would learn about AI. And only then would you focus on how to apply AI to law.

However, if your goal involves merely getting a handle on how AI might apply to law, without necessarily understanding AI in detail, then you could start by reading something like A Legal Theory for Autonomous Artificial Agents. I haven't read that book and I know little about the application of AI to law. You might find a better book for your pursposes. I did a quick search on Amazon, suspecting to find something like it, because I felt certain that a substantial amount of work on applying AI to law has already happened. Here's a quote about the book.

“An extraordinarily good synthesis from an amazing range of philosophical, legal, and technological sources . . . the book will appeal to legal academics and students, lawyers involved in e-commerce and cyberspace legal issues, technologists, moral philosophers, and intelligent lay readers interested in high tech issues, privacy, [and] robotics.”
