It even concludes with reasonably good advice: to pass a Turing test, AIs should say things that are true, and tap into human emotions. To me, this disproves the idea that it's "not saying anything". It's definitely saying something, and that something is both true and not commonly understood by the general public. It is therefore capable of "teaching a basic skill".
I find that very impressive, and I'm surprised that so many others here don't.
