He doesn&#x27;t appear to ever have written about it. This is a very odd way to criticize him. Why not focus on his published work? He wrote a lot about QM, so his purported total lack of understanding should be evident in that body of work. Much better than digging up some rumors that you can&#x27;t even provide a reference for. (The commentary that you&#x27;re referring to appears to be rather well hidden, by the way.)
