> Something went wrong with music and culture in recent times. Participation became consumption.

I think closer to truth is: Participation became production.

More people are doing more things (including with instruments) but often times in a digital setting, sometimes more isolated and sometimes much more public (think: Twitch streams where chat is part of the whole social experience in a way that was never true for TV or other live events of that scale). More participatory online and more individualized as consumption, while some older forms of face-to-face amateur participation have become less socially normal or less visible.

This says not so much about music or culture really; it seems fairly aligned with where our lives and how we connect have moved more broadly.
