It truly is
A true semantic web and search is only a part of it
So for eg, you can easily have an app that can find you friends or dates who share the same nuanced political views, tastes in music, academics, etc, any view based on the users interactions with the knowledge base blockchain

there's far more to the features of course, but that's something I missed in the article
