Children often have questions that they are not comfortable talking to their parents about. And their peers can often be more clueless than they are. Or maybe they just want to understand the world they live in with something that is more fun and engaging than reading Wikipedia.
What's harming children right now aren't services like this. It's the peer pressure and unreal expectations being set by social media.
kinda really fucking depends on what "services like this" are telling them. Remember when the national eating disorder hotline replaced it's humans with chat bots that started telling people to just eat less?
And here they are, growing up with this technology, entirely unlike anything available to us in our childhoods. But one thing remains the same: if we shut them out altogether, they'll route around us and find it on their own.
A teetotaler myself, but the "not one drop" mentality doesn't really make a ton of sense to me. Not because I want my kid using AI or alcohol, but I'd rather him try it under my watch than go out and find it on his own.
But if this is a feature that parental controls cannot limit, then I honestly don't know what to say other than, perhaps we're fucked as a society.
