What happened to gmod?

I think in large, most of the community around the 2010 to 2014 time has grown up, and out of GMod, however thanks to youtubers there is a younger audience playing GMod now - however in a few years times they will have matured a bit, to that point where a lot of players were about 2010 to 2014 so we should see a resurgence of fun and creativity back in GMod.
