  How to make artificial intelligence (AI) systems safe and aligned with human
values is an open research question. Proposed solutions tend toward relying on
human intervention in uncertain situations, learning human values and
intentions through training or observation, providing off-switches,
implementing isolation or simulation environments, or extrapolating what people
would want if they had more knowledge and more time to think. Law-based
approaches--such as inspired by Isaac Asimov--have not been well regarded. This
paper makes a case that effective legal systems are the best way to address AI
safety. Law is defined as any rules that codify prohibitions and prescriptions
applicable to particular agents in specified domains/contexts and includes
processes for enacting, managing, enforcing, and litigating such rules.
