As an introverted tech nerd, the underground club/rave experience changed my life so much for the better, including numerous trips to Berlin. But, all culture is a product of its time - to freeze these venues in time as a Disneyland of the millennial experience is missing the point (especially with techno, an inherently futurist genre).
It has been interesting to grow up with clubbing and see it go from an underground youth subculture that seemed to radically reinvent itself every year to a crowd of the same people but now middle-aged. I wonder if this is what happened to people who kept going to 80s nights, or if people in their teens and 20s just don't "go out" in the same way any more.
So just like the grunge nights, northern soul all-nighters, lindy-hops and penny socials before them, a cultural form of creative destruction will see this too fade into history to be replaced by whatever expression the new generation finds to express their situation, which is different in every way to the world that birthed Berghain.
