Could an artificial intelligence be considered a person under the law?

Humans aren't the only people in society – at least according to the law. In the U.S., corporations have been given rights of free speech and religion. Some natural features also have person-like rights. But both of those required changes to the legal system. A new argument has laid a path for artificial intelligence systems to be recognized as people too – without any legislation, court rulings or other revisions to existing law.
