Good question. I hope, the parent doesn't mean literal arms, that would make him a willing or unwitting troll.

Skynet was always a matter of time, it's simple systemic determinism. What we can do about it isn't as simple, unfortunately. It's possible to do something but it's neither simple, nor glamorous or painless, it would require people prepared for both complexities and hard life. Are there enough of them around? I dunno.
