Something being old doesn't meant it's false. It even has a name: https://en.wikipedia.org/wiki/Appeal_to_novelty

Perhaps some folks don't get the reference.

You can find a lot of ancient people saying it was happening. They were obviously wrong, right? Things are better now than then, so they were wrong. Nevermind that many of them were speaking of real social decline, not of humanity altogether in the long run but of their own society in a less global sense. When Socrates was bitching about "kids these days", Athens was peaking and a long period of uneven decline was starting. So really, he probably wasn't wrong.
