Personally I find everything you listed here safer than letting a kid have unfiltered unlimited access to TikTok.

You know a gun or a bomb is dangerous, so you'll probably be careful with it. The gun and the bomb are not engineered on purpose to hook you by exploiting your dopamine pathways and get you to shoot yourself or blow yourself up.

EDIT: I'm being a little hyperbolic here, but I'm also talking about aggregate harm and intent to harm. I'm really being hyperbolic to bash what I consider to be the key villain in this story: addiction engineering, a.k.a. "maximizing engagement." This is the root of all evil.
