I don't hang out with a lot of teenagers, but what I see of them paints a sorry picture. Rampant mental health issues, many infants I see glued to junk on iPads that would make children's TV of the 90s the height of intellectualism, etc. Do you really think there are reasons to be optimistic about the new generations? What little of them there will be, given the drops in fertility rates.
