I am not at all clear why you would say this. In fact, I think you are committing an argument from authority in the reverse. You refuse to listen to this guys because you assume that they are not authorities. That's just bogus and I am sure you know that. Instead, you should listen to Hawking discuss metaphysics and decide if he is worth listening to. You would, I think, do exactly that if it were philosopher speaking. Why should I listen to Hawking discuss metaphysics? I only have limited time, and I'm entirely unconvinced that would be a good use of it. It's not that I'm refusing, merely that I have no inclination to because I don't have any expectation of particular insight.
