EDIT: A lot of you are reading into the tweet while still somehow agreeing with the overall message. No one is saying we should eliminate music programs or that we should teach toddlers about healthcare plans. The tweet is making this thing called a --checks notes-- joke, that also conveys the message that schools could teach more practical skills that young adults will need going forward.
This isn't really a joke though. It's a commentary on preparedness for adulthood and the current version of the machine.
If you think it's not a joke, you're kidding yourself.
