I think it's the fact that this is so ubiquitous and normal that no-one has bothered with a name for it yet, except maybe “history”. For my parent's generation, Elvis Presley and The Beatles were something new and revolutionary while for me they represent boring establishment. This is just how things go. “Transformative” only ever holds for a specific moment in history. And human history is nothing but those transformations becoming the new normal.
