Or how about calling that vast, thriving industry "weak AI," or "clever algorithms," which is what they really are. The original definition of AI was what we now call strong AI, but after some lesser problems were solved without actually creating strong AI, we had to come up with some name for those.
And then to reverse it, imagine that the world really is some kind of massive simulation... and that there are backups of the save()-ed :)
IMO, AlphaGo isn't "intelligent" because all it can do is play Go. For example, it can't be taught to play chess without completely reprogramming it.
Surely it's using a lot of clever algorithms, but where's the intelligence?
TBH, there's not much point to this post, because the intelligence in AI has been twisted more towards your usage almost since the beginning.
Even if Alpha-Go could play chess, manage air traffic control, and play GO the same time, it would never know it was doing that. As you mentioned above, Alpha-Go's "intelligence"is specifically pre-programed algorithms and accurate numeric inputs. If it can't create it's own algorithms or translate abstract data into numbers it can crunch on it's own, then there is no intelligence there. It just "smells" like intelligence.
For a much more detailed exploration of this topic, I think Wait but Why's article did a pretty thorough job: http://waitbutwhy.com/2015/01/artificial-intelligence-revolu...
