I've found that, eventually, it is easy to understand him. There's a
lot of obfuscation and hand-waving and redefining of terms, but the
mistakes become depressingly clear after a while.

I see that my predication is correct. New threads appear like the hydra
but there will be no explanation of why his f is surjective and your
identity function is not.
