Maybe because it associates with shit and they don't like dark /milk chocolate 🤔
Are we eventually going to ‘run out’ of new combinations for music, art, language, etc.?
Don't think so. I believe people will always find some new ways to express themselves, new instruments to do that, new styles. It might not necessarily will be as beautiful and great and that as it is now or was in the past as just like everything art is evolving all the time
