I never spent any time "worried" about cultural artifacts.
Inevitably, these get thrown on the scap heap of history.

Kids will worry pretty much about the same stuff we worry about:
-- finding and keeping a job
-- paying the mortgage (or rent)
-- maintaining a relationship or family
-- maintaining a vehicle
-- communicating well (whatever the medium)
-- staying healthy
-- taking advantage of liesure time
-- retiring in comfort
IOW, the mundane, yet important stuff of daily living.
