The First Amendment of the U.S. Constitution protects “the freedom of speech.” Courts have also said it protects “freedom of thought.” But does that mean we have a right to speak with or listen to the speech of robots? Does it mean we have a First Amendment right to recruit robots to help us think or change the way we think? By “robots” here, I mean the robots that are the primary focus of this book: Humanoid robots that might not only emulate the way we solve intellectual challenges or express ourselves, but also emulate us physically – by taking on a physical form similar to that of human beings and moving and acting in the physical space of our homes, workplaces, or other spaces, and not simply the virtual space on our computers.
