A comparison I might make is that AI fanaticism is like the God-of-the-gaps phenomenon. There's a great deal of ignorance about what intelligence is, what computers fundamentally are, and so on, and some people like to fill that void with all kinds of fanciful and unjustified stuff. Perhaps they also feel greater justification in doing so because a few famous names, many of them popularizers, have done the same. Science fiction is fine -- it can be fun watching or reading about fictional AIs -- but many times we're not dealing with mere imaginative storytelling but uninformed and unsophisticated claims that do not withstand philosophical scrutiny. What falls under the heading of AI has proven to be an immensely useful tool for automating certain kinds of things. Observing these successes, some may happily apply the aforementioned God-of-the-gaps analogy to human intelligence. However, that would be a flawed analogy because these successes have not brought us any closer to achieving human intelligence any more than adding an indefinite number of natural numbers together gets you the negative square root of 2.
It's important to distinguish between intelligence and the power a tool can offer for good or for nefarious ends. If successes in AI have proved anything, it's that direct application of intelligence is unnecessary for many tasks that previously no one knew how to or was practically unable to perform using machines.
