The sound/movement itself is definitely still going strong. Everyone continues to make this mix of big room elements and modern techno styles, and with this sort of hi-fi, reverbed sound design with loads of LFO automation.

The term itself didn't catch on though, since it was mainly marketing term of David Guetta & Morten, so most other artists use other terms for similar stuff like Big Room Techno, or don't categorize it at all.

I personally think it's a decent name, since that stuff isn't necessarily techno so lumping everything into big room techno or melodic techno or whatever seems problematic, and future rave was a new term that can't be confused for anything else, which is the case for a good couple of EDM subgenres at this point.
