It is important to distinguish between the geographic and magnetic poles. They move at different speeds. Continental drift - tectonic plates move very gradually, so that for example North and South America were once connected to Europe and Africa. That takes place very slowly. On the other hand, the magnetic poles, where the needle of a compass points, can shift very much more rapidly. Over recent decades the magnetic north has been shifting at a rate of about 34 miles per year. That is significant, by no means imperceptible. It is also known that the magnetic north and south have changed places more than once in the past. I'm not sure of the timescale.I don't understand that hypothesis well enough, and need to study it a lot more. I agree that the idea that gazillions of tons of earth mass inertia can just "stop", or flip 90 degrees in a day seems absurd to me.
