Yes, I'd be happy to give that a go.
I think, as I was alluding to at the end of my statement, what is going to be determined as fair or ethical is going to be extremely context-dependent. Maybe the highest level we could go to in terms of having guidelines for what constitutes an ethical or fair decision would be at a sectoral level, at which you have existing regulation that gives you some restrictions concerning what is considered permissible or discriminatory, because these things will vary across different sectors.
Really, it's something that can only be answered at that contextual level. I think maybe we have a head start in AI that will be used in professions that are already licensed or legally recognized as professions, where they have fiduciary duties to the people they serve, because they have these very long histories where they've developed best practices, guidelines, principles and lower-level norms, basically, to define what is a good behaviour and what is a good decision.
It's a difficult question, but I think that's how we start.
