I assume science fiction is to blame. All the AI were either written as machines of pure logic that exploded when exposed to the liar's paradox, or conscious like Star Trek's Data.

(Though at least with Data the script writers had other characters openly dismiss the possibility he was sentient; the technobabble may have been nonsense, but treat it as a space opera and look at how they portray the human condition through each character and it gets much less absurd).
