@datarama @coder right. I'm a bit surprised because the last times I've evaluated them, I tend to resort to them when I'm stumped with something.
The generated answers are rarely correct, but frequently they are helpful (maybe just of the rubber duck effect). Which is somewhat impressive because if I was stumped, I assume I'm not asking easy questions.
(I don't think they're useful enough in the stuff I like to work on, though.)
