Meh. He made a technical point about what magnitude means in math when I was using it colloquially. He tried to rebut a self-evident point (that vaccines have the capability of ending the current crisis, if not the actual pandemic, while masks have utterly failed in that regard despite very rigorous mandates such as in Spain) by using said technicality and then went into crazy land by making a point that masks and vaccines are roughly equivalent (which he later had to clarify and back down on). Not exactly his, or your, finest hour....of the many stumbles, that overreach was probably one of the worst because it puts him in the same crazy train as "masks are as good as vaccines". Sorry if the crazy train caught my attention more.
