Two things I collect are vintage video games and music. The general sentiment of both those hobbies are going in drastically different directions.
1. Vintage video games are becoming more more desirable
2. Vintage music is becoming abandoned en masse
I often wonder why this is the case, and I think it's a generational thing.
Gen Xers and Boomers define themselves by music.
Gen Z and Millennials define themselves by video games.
As Boomers die out, few people want vintage music.
