I'm thinking the objective function could have constraints on the expected number of times the AI breaks the law, or the probability that it breaks the law, e.g.
- only actions with a probability of breaking any law < 0.0001 are permissible, or
- only actions for which the expected number of broken laws is < 0.001 are permissible.
There could also be separate constraints for individual laws or groups of laws, and these could depend on the severity of the penalties.
Looser constraints like this seem like they could avoid issues of lexicality and prioritizing avoidance of breaking the law over everything we want the AI to actually do, since the surest way to avoid breaking the law completely would be to never do anything (although we could also have a separate constraint for this).
Of course, the constraints should depend on breaking the law, not just being caught breaking the law, so the AI should predict whether or not it will break the law, not merely whether or not it will be caught breaking the law.
The AI could also predict whether or not it will break laws that don't exist now but will in the future (possibly even in response to its actions).
What are the challenges and problems with such an approach? Would it be too difficult to capture such constraints? Are laws too imprecise or ambiguous for this? Can we just have the AI consider multiple interpretations of the laws or try to predict how a human (or human judge) would interpret the law and apply it to its actions given the information the AI has?
How much work should the AI spend on estimating the probabilities that it will break laws?
What kinds of cases would it miss, say, given current laws?
Agreed that "human values" is harder and more indeterminate, because it's a tricky philosophical problem that may not even have a solution.
I don't think "alignment" is harder or more indeterminate, where "alignment" means something like "I have in mind something I want the AI system to do, it does that thing, without trying to manipulate me / deceive me etc."
Like, idk, imagine there was a law that said "All AI systems must not deceive their users, and must do what they believe their users want". A real law would probably only be slightly more explicit than that? If so, just creating an AI system that followed only this law would lead to something that meets the criterion I'm imagining. Creating an AI system that follows all laws seems a lot harder.
I think this would probably have been true of expert systems but not so true of deep learning-based systems.
Also, personally I find it easier to tell when my actions are unaligned with <person X whom I know> than when my actions are illegal.
