Did I say "all" or "none"? No, I did not.

I was a wise-ass kid. I caught my teachers in mistakes. But overall, their error rate was very low.

For example, I eventually studied mathematics, so i got to check their work. Not one teacher had taught me any false mathematics. In some cases, they had taught badly, or taught old, inferior techniques, but no one taught me falsehoods.

AI's error rate is something like 20-40%. That is over an order of magnitude too great to be an effective teacher.
