Well, no, they don't, but I'll agree that some do.
I am sorry, but you are wrong. I was at the AAAI conference this year, and there were thousands of AI researchers there working on some pretty amazing stuff, but not one of the people I talked to was like "oh, yeah, we're not doing *real* AI, we're just faking it"
Whether you like it or not, things like neural networks, genetic algorithms, deep learning, data mining, decision trees, fuzzy logic etc... are ALL real AI. Simply because it doesn't fit your Hollywood and TV induced concept of what AI is, doesn't make them any less AI. To call them something else would be asinine, and basically amounts to telling a whole field of research that they aren't doing what they think they're doing. Do you also think that cars explode on impact?
What you are talking about is called "strong AI" or "artificial general intelligence" (AGI) - which is an entire subfield of AI.
You're the kind of person that would tell a pilot that they're not REALLY flying because they're strapped into a vehicle, and not outside in the air buck naked and flapping their arms, aren't you?
