No, they're just different—and we owe much to the generations who came before us. You have to view each designer's work in the era in which they lived. Imagine what Jan Tschichold would do with todays tools and the decades of type history that have followed his writing "Die Neue Typographie"!
Where newer generations of designers are typically ahead of older generations of designers is in grasping the interactive medium, for the obvious reasons. But that's more about knowledge of the medium than design skill. Many interactive designers have no idea how to pre-press a job for print, so I'll call that one equal!
