I don't think Robert Downey Jr. is the best actor out there, but nevertheless he is human and I would say he is working very hard as an actor. That 'celebrity' tag is something society gave him and he must carry it whether he wants it or not (if he wants to continue to be actor off course).
Not only AI will disrupt jobs it will disrupt the way we live on this planet completely. It doesn't even matter if we don't want it to happen, this kind of economy we have today will force it happen.
