i think people here are just talking about producers who get a bit softer as they get older.
well that is quite often true...
and maybe some older guys don't bang it like they used to
but musicianship stays with you all your life
it doesn't rub off ...or get used up as you get older
i think some of the older guys have just changed their syle
and for all the audience they've lost they probably gained the same amount of people who are into their newer sound. ( beyer for example)
so no the older guys haven't lost it in general
they've just changed , probably aware of the fact that there's a lot of new guys who play banging , so they've moved to something else
nothing wrong with progression.
