Well… judging by his behaviour on all the times he's been told "no" by domain experts, and that random reward schedules are highly addictive (which in this context means "on some occasions he's even correct when he tells experts he knows better"), I think it's very plausible that someone told him what Epstein was and he ignored and/or fired them for doing so because he didn't want it to be the case. But that's the positive spin, where Musk actually didn't know and was simply an idiot, and at this point I'm tired of giving him the benefit of the doubt.
