The only major thing that seems to have changed are the names of the distractions.
this is a true statement, but idk how different it really is for the kids. when i was a kid i would happily spend hours rereading the same garbage star wars expanded universe books over and over and over, even though i had basically memorized the plot. with the abundance of content, i doubt today's children would be as satisfied to revisit the same thing so many times, but i also doubt that they waste much more time than i did.
My point is that the nature of what kids do at parties hasn't changed in any significant way to support your original claim that there are "so many basic things we just don't learn how to do anymore".
