It's pre-emptive in that it doesn't address any of it, you just says that "this" has been said about other things, supposedly implying that since this somehow refutes even one sentence in the article, making all discussion of any details in it superfluous.
But you don't even have the courtesy to say that, just leave it implied, and then paper that over with some fluff about the Beatles as if that could distract from that. So you "stand behind" stating a triviality and then not saying what you cannot directly defend.
About "older generations rejecting change", that old, dank chestnut... conveniently ignoring all the changes welcomed with open arms by older generations, too, and all the young people who think this stuff stinks. It's a fake narrative to skirt actual argumentation. More importantly, resistance against these methods, as well as the people who rationalize them, is just as much "progress" as is inventing and employing them.
