Sufficiently good text autocomplete is indistinguishable from intelligence to an impartial observer, and that's the only honest criterion for intelligence.

Can't tell if sarcasm

I'm a little shocked that people discussing this topic could be so far apart! I'm completely serious.

Have you ever thought about how you would determine if an arbitrary given entity is intelligent or not? I think you'll agree it would require some kind of test. You might agree that the test would have to involve bidirectional interaction (since otherwise it would be impossible to distinguish an actual person from a recording of one).
