As a term, it does seem to be popping up more, but it feels less like an accepted part of our vernacular, and more like a small group of people trying to coin it for themselves. I'm generally dismissive of anything I'm seeing lately that embraces that term.

As far as the actual blockchain tech goes, it is interesting and has its place. But people who just are stuck at "blockchain = currency" and are trying to get rich off it are probably holding it back because few are truly looking at it as a tool and finding good uses cases for it.
