I can try to answer 3 for Marcus. Imagine that AI policy is a soccer game for professional soccer players. You’ve put in a lot of practice, know the rules, and know how to work well with your teammates. You’re scoring some goals.
Then someone from an interim/pick-up game league who is just learning to play soccer comes along and tried to be on the team, or—in this case is not even aware of the team? If we let them on the team, not only do we look bad to the other team, but since policy is a team sport, they drive our overall impact down because it’s kind of dead weight that we now have to try to guard against for things they do that they think are helpful but are not, depleting energy and resources better spent on getting goals.
That’s just completely false. Sorry I can’t say more.
