Do these things really directly descend from pure AI reasearch? Or are they really the result of a bunch of clever, yet extremely specialized algorithms, independently developed, combined with an incredible increase in hardware power? Not to say such things aren't incredible (Google clearly has changed the world), but is it clear that pure AI research has paved the way?
From an outside perspective it seems the "God of the gaps" argument - AI is what AI researchers haven't done yet - is used as a smokescreen to cover up that AI research hasn't really done much in the last 30 years. (Counterexamples without hand-waving?) And not only that, but it consistently, wildly, and systematically makes incredible predictions that don't come true. For example, Kurzweil is clearly a genius, but also wildly deluded and wrong about his time-frames.
Some of you guys will down-mod me for saying this, and you're the same people who also won't admit my side was correct when, in 20 years, automated translation tools still suck and you'll still be making the same old arguments about how AI is what we haven't done yet... (but in ten years you'll be able to upload your brain!)
