You say they're older as a joke, but it's very much relevant. Old artists dismissing the developments and approaches of their younger colleagues is a tale as old as time.

And yet - dismissing criticisms of older people by younger people as "you're just old" rather than answering the criticism is just as old.

Older gens hated rap when I was a kid and I was thirsty to defend it with supported reasons

Kids today just say OK boomer and move on. Bc they have no defense .

Established older musicians hated The Beatles.

Generalizing criticisms as the same as past criticisms is a sidestep rather than a point.
