Haha what? The kids didn't just grow up and everyone else stopped using computers magically. Also kids aren't inherently better at tech despite growing up with it, most people still specialize in their chosen careers. They are better at seeking out information since they're conditioned for it but that doesn't automatically translate into knowledge. User interfaces are a whole different beast anyway, most people get annoyed at them and give up, they don't even attempt to customize.
