<< Getting on a high horse and lecturing other people on social media isn’t going to do anything.
I disagree. Ostracism and generic shaming may be necessary. My kid is barely 4 and his cousin's already were fielding cellphones during our family gathering. There are times high horse riding is absolutely necessary.
Necessary maybe, but insufficient. Shame other plebs all you like, the predatory tech isn't going away until we start ruining rich people over it.
Saying something in a social setting when someone is behaving inappropriately for that social setting is reasonable.
Pulling out your cell phone to post your own angry rants about how your cousins were using social media is just pointless grandstanding.
