Him being at all on the spectrum means a bit less than the actual degree at which he is, I may be on it as well (Albeit slightly), had unrestricted internet access, and while I'm not confident on saying I would do it differently than what my parents did, I have many arguments for limiting some of it even for an aware and allistic kid
It's a large scale problem, I can't expect the parents to know the intricacies of everything on the internet, but I'd expect them to try and be aware of those parts their kid does take interest to a degree their competency allows
Regardless, while I've always considered this kind of chatbot something a child should be strictly kept away from, because you can't know when it will tell a child to do this, or to glue pizza for a less dramatic example
I'm okay with it not being marketable to children, but the steps neccessary to limit them further than that make me uneasy
It's not the first time it goes horribly wrong; and not having the AI do it doesn't mean people won't just be even worse, see Chris-chan
