I agree, but I also wonder how feasible that is for a lot of parents.
The older I get, the more astounded I am at the fact that nobody in my family has social media brain rot. Or political brainworms. My grandparent's generation is mostly dead, sadly, but there are 3 living generations ranging in age from 0 to 78 and dozens of people and we're all fine. This is regardless of educational level (ranging from HS dropouts to MDs), political affiliation (everything from center Dem to anarchists, socialists, and even some Christian conservatism for spice), or religion. If I had to pinpoint the difference, it's that we were all raised by and surrounded by adults that understood the interaction between technology and daily life. But most people becoming parents don't have that, the Internet just crashed into their life and upended a lot of what they thought they knew without leaving anything in its place.
I also question that it's solely based on the parents because the older I get (I'm in my mid 30s), the more I think access to non-parental adults with this ability is the key to our relative stability, particularly tech-knowledgable adults that openly disagree with each other. Kids do stupid shit, especially when they're adolescents. They will disobey their parents/ignore their advice because it's part of growing up and figuring out their own values and boundaries, but when an entire group of adults who don't agree on politics, religion, or worldview all agree that something is a bad idea, then that idea becomes a cultural taboo. I don't think my paternal cousins and I have ever voted for the same things and I'm the weirdo gay heretic socialist to their traditional Catholic, but both I and my cousins are going to agree on the important of things like basic op-sec and when to tell people what online. So even if their kids rebel hard, the rebellious adults are going to reaffirm 'don't put your hand on the stove/do things like delete metadata from photos'.
I don't know if there's enough cultural knowledge communicated to the parents for them to parent effectively even though I agree that's their job.
