Absolutely, Dick. If you take a completely arbitrary date of, say, 1964 for the "folk revival", there's a significant difference in the perspectives of the scene from 16 years later (1980) and 53 years later (2017).

As an aside, there's a wonderfully double-edged comment on Dylan which had me sniggering:

His songs became rallying-points for both the protest movement and other young singer-songwriters, to whom he demonstrated that a mediocre voice and limited guitar technique were no barriers to success."
