What a complete waste. Don't you have any desire to ask him about, I don't know, his own ideas? Or any kind of substantive question at all, instead of just his competitors?
I don't understand the desire to keep waging this battle against string theory, supersymmetry and every other idea other than what Rovelli works on. Surely nobody is illuminated by the entirely negative message, let alone convinced. Surely nobody is laboring under the misimpression that Rovelli's approaches have been any more successful at making unique predictions or being experimentally observed than his competitors – quite the opposite if anything.
One is left with the impression that Rovelli's thoughts on physics are defined by what he is against rather than for, though I'm sure that has much to do with the terrible job by the interviewer. One also gets the impression the interviewer hasn't heard of anything interesting happening in theoretical physics over the past decade besides arguments about string wars and multiverses. I'm sorry if that's the case.
