You gotta love the opposition running out of things to say so they resort to calling a renown brain surgeon dumb
But he is saying dumb things. Intellect is an intersection of IQ, spatial reasoning, verbal/non-verbal processing, processing speed, etc, it's to general and to nebulous to quantify accurately.
However, actions and words are often the best indicator. Rote understanding of procedure is not intelligence. He is saying things that show he is either not well read on the subjects, or willfully lying, if it's the latter, he is not that smart. Once you get into the 140's of iq silly ambitions, lies and other bullshit are non-existent, truth is usually all that matters, geniuses won't subvert, ever.
