I'd say this is the long-term view of where Google is headed - or really, where search is headed altogether. We left the world of pure text match years ago, but not by a lot so far.
It's definitely something to keep in mind as we try to make sense of the way SERPs are evolving. Right now, experienced searchers might not even formulate a search such as "the ten deepest lakes in the US" but would probably come at this idea from related searches that stand a better chance of finding a text match - and then go on from that initial set of findings.
The article states "while 200 million entities is a lot, the world of knowledge is vast." Indeed. Given all the possibilities that a true AI would need to address, 200 million entities is a mere sneeze.
