It looks like an airy, hand-waving dismissal. Zeno's paradoxes are like the geometric demonstration that two unequal-length line segments contain the same (infinite) number of points, and/or the demonstration that every point in the real number line has a corresponding point in the subset segment of the line between 0.0 and 1.0. In fact, Zeno's paradoxes basically are those paradoxes turned into word problems.
Cantor for sure, who explored the properties of infinite sets, deserves better than he seems to be getting from Lynds here. So there will probably be hackles raised.
I think he's arguing that the traditional math is right, but it doesn't model reality. It's beyond my pay grade.
