Alright, but I don't really care about any of that at all. Do you see any flaws in the actual math or logic of the paper?
> In nature, all motion can be described by the principle of least action: motion minimizes action.
It is wrong. The actual principle is that the trajectories are stationary points of the action - not minima.
(Edit: It is wrong even with the "locality" caveat that the author later adds.)
