Like the other commenter in this thread who says "... not social suicide ..." I would suggest just implementing the rules yourself regardless of what society is doing. The trend (as you can imagine) is definitely still going younger and younger. And unless you have the funds to fight off the marketing teams of Google and Apple, I imagine that will continue.

My kids are fine. Even with their parents fighting tooth and nail to keep them off devices as much as possible, they will still be on them sometimes (in your home or out of it). Maybe my kids are just weird to not be craving social media - just being able to send text messages to her friends seems to be enough for my 14 year old currently. Is that the same thing? My observations say "definitely not".

They complain about it sometimes, (and I complain about their usage sometimes) but nobody is really angry and everybody is really reasonable. Your mileage may vary.
