I've done some teaching and looking at students (13-15 years old mostly) their differences in personality, virtues and flaws seem more pronounced than when I was in school. The "good ones" are more ambitious, resourceful, and good-hearted than anyone I can remember from my time in school, and the bad ones ... are really really dumb.
I think technology acts as an amplifier pushing kids towards extremes. Some will get all the good without the bad, and others the other way around. I don't see how anyone other than the kids' parents can help them here. Remember the median age in the United States is 38.5, so the extent to which we're experiencing cultural decline, internet insanity, tiktok brain, etc. is still the fault of previous generations.
In the end, we have to believe in the zoomers.
