"Trivial" and "naive".
And I'm looking at Nima Arkani Hamed, he's either a physicist or cosmologist or both, but in every lecture or interview, if he doesn't use either word "trivial" or "naive" every minute or so, his forehead veins start popping out and he starts sweating. He can't be bothered to explain what is evidently obvious... to him, in his ivory tower, so he takes constant fucking non-explanation shortcuts.
