Nightclubs aren't even on their radar, which is very different to when I was 18.
It's becoming pretty common to know a few amateur DJs / music creators and if you have some decent speakers they happily mix for a part of the night. When they're done it's back to DJ ipod.
There is also plenty of raves where I live. I feel the atmosphere is much more enjoyable there than in night clubs
There was a real startup-like scene around this in the 90s in Europe. You actually need impressive organisational, networking, and marketing talent to make a warehouse or field rave happen.
The festivals this spawned eventually turned into gigantic multi-stage events with the latest audio, VJ, laser, and other tech.
Unless Covid restrictions become permanent, I'd expect a similar cycle to repeat, although perhaps with different properties. (Empty shopping malls? Maybe even empty office blocks?)
The problem of “unrooting” (emigrating, being nomad and torn from the social fabric) is a serious civilizational issue, similar to when workers in XVIIIth were poorer than farmers of the same social level, because they had no land if things went bad.
