He just pointed out that their demonstration video can be easily explained without any superconduction. I don't see why you need to be a professional physicist for that.
Do you also need to be a physicist to point out that their "levitating" sample is in fact still touching the magnet?
Or that the "0 resistance" is actually 1000x more resistive than copper.
