Nice assumption! Unfortunately, your mind reading skills aren't the most perspicacious. I actually have five kids. How many do you have? And how old?
Turns out that just being a minor doesn't make you technologically incapable. My 16 year old learned how to use VPNs and torrents when he was 12. Unless you're prepared to force everyone on the planet to use government or big tech controlled everything and ban terrifying technologies like open source, it's not going to be hard for them to work around them. Maybe we should have government cameras in all of our homes with AI constantly observing, transcribing, and recording everything we do or say. We could even hook up an MCP server to law enforcement so the cops can be sent ASAP upon any violations. A robo-car could show up within minutes and the cameras could announce that you must get in. We could start with forced re-education, and escalate to imprisonment on multiple offenses or if the severity of the violation exceeds some threshold. Might make sense to just have all the kids taken from home at birth and raised in a safe government run rearing house. Then we could make sure they're getting well educated in the manner that our rulers at the time desire. Trump would make a great father figure and example right? No? Why don't you want to protect the children? Is there anything not worth doing to protect the children? Won't somebody please think of the children?
