> The creators of the media are becoming more and more my age.
I'm a boomer so the opposite is happening to me. The people in media look more and more like children to me. So I can't tell if the fact that they seem to be speaking more childishly is real or just the expected bias from an old fart. I should experiment with getting AI to put the same words in Walter Cronkite's mouth to see if it changes them.
Betting on "it's me that has changed" has rarely been false throughout history. Humans have mostly been the same throughout the ages.
