It's one or the other!
I don't think there's much of a barrier to entry to learning to dj for younger people. I'm sure you can get a starter kit for less than £300. if anything it seems like djing with a controller at home as a hobby has become the logical next step for loads of people (who might not want to actually DJ out n about) from enjoying music in playlists.
that runs into the thing about plastician on twitch. there's a similar thing with younger music producers all jumping in discord to chat about producing dance music. it's like Ableton experienced as another video game. dance music provides the templates and the inspiration for trying out some new plugins and production techniques, but it feels like it's less linked to actually going to experience that in a club, you just share it in discord when you're done.
I swear I've seen someone on Alex McLean's tidal forum mentioning they're working on a keyboard with knobs.I don't even dj with a controller, qwerty keyboard rn. They should just make a keyboard with knobs and wheels which I can remap in vdj.
