The term AI researchers have used to describe what you are talking about is Artifical General Intelligence. And they've made a distinction because there is no reason an advancement over human capabilities shouldn't be called AI. Sure, learning how to play Go better than any human alive doesn't mean that AlphaGo can learn and interpret languages, but that doesn't mean it's not intelligent. Even human intelligence is not homogenous in its capabilities. It's obviously speculative, but I'm of the belief that AGI will never exist the way fanciful minds imagine it. Rather AI will evolve slowly, and systems will incorporate small advances one by one until one day we don't really care to distinguish between AI and AGI. It will literally just be a collection of capabilities ("just a computation") that are well understood and have lost all semblance of magic.
