Interesting paper. I agree that he is probably technically correct, but I think he downplays the fact that all over physics people say "never" when they mean "with probably less than 10^-1000. For example, in classical thermodynamics there is a nonzero probability that all the air molecules in a room will happen to travel to one side, violating many laws of fluid mechanics. In quantum mechanics the situation is even worse, where basically anything can happen with nonzero probability.
