I think the argument against LeCun is simple: while it may be true that AIs won’t necessarily have a dominance instinct the way that people do, they could try to dominate for other reasons: namely that such dominance is an instrumental goal towards whatever its objective is. And in fact that is a significant risk, and can’t be discounted by pointing out that they may not have a natural instinct towards dominance.
