Intelligence and consciousness are at the fringe of our understanding, so this skeptical approach seems like a reasonable and scientific way to approach categorizing computer programs that are intended to be called “artificial intelligence”. We refine our hypothesis of “this is artificial intelligence” once we gain more information.
You’re free to disagree of course, or call these early programs “artificial intelligence”, but they don’t satisfy my crude hypothesis above to a lot of folks. This doesn’t mean they aren’t in some ways intelligent (pattern recognition could be a kind or degree of intelligence, it certainly seems required).
