I assume this refers to pop music which was mainly available after mass media became a thing. They’re probably not interviewing Edward Von Dickensachen about the Chopin concert he attended when he was 12.
It’s not talking about music, it’s talking about humans. If this chart is meaningful, it should apply regardless of fashion. Otherwise it’s not talking about humans, it’s talking about recent trends in music.

I think it’s talking about human development in relation to a particular art and medium.
The art of pop music and mass media distribution (radio, tv, internet) didn’t exist 100s of years ago.
To me it’s similar to a chart talking about something like computer use in human development. Those didn’t exist 100 years ago either.
