Wikidata, SPARQL, and RDF in general. And I guess semi-relatedly things like Prolog? I couldn't agree more. I know a lot of this kind of "semantic web" stuff has some pretty vocal detractors and that adoption seems limited, but I still think there is a ton of "meat on this bone". There's just too much potential awesomeness here for this stuff to not be used. I think this is an example of where incremental refinement is the name of the game. As computers get faster, as we get more data, as algorithms improve, etc. we'll get closer and closer to the tipping point where these technologies really start to reveal their potential.
