You should try to study a bit of mathematics.

And recks not his own rede."



Then according to WM, every derivative must always equal 1 at all
points, and f(x) = |x| must have a derivative at x = 0, and lots more.

That's nonsense.

Maybe, but it is WM's nonsense, not mine, to argue that functions must
continuous at points outside their domains.
