"I have begun to notice that the maturity of those born in 2000 and above has dropped considerably as the years go by."

Insane opinnion.

Im 20 atm, not very old but still old enough to objectively compare my childhood to the current youth and I can say there is no change. The things we did and kids do nowadays are a bit different ofc, but to say because of smartphones suddenly the "new gen" is dumber or less mature is retarded. Society is changing of course but people and culture don't massively change in a such short timespread (<10 years).
