There's some grim humor in the fact that the poster reflects on his sister's use of chatgpt, and just ends on that point. I have to wonder if he decided to talk to her or his parents about the situation. I didn't see anything in the post to suggest it, just a "this next generation is cooked." Who cooked them is the question? Children won't raise themselves generally.
It makes me think this whole article is maybe just rage bait.
There is a legitimate problem at hand here with our relationship with tech and how children.. are left to their own device with that stuff. On purpose, for the most part: the parents seem all too happy with the ability of those devices to make their kids shut up and stay constantly distracted. Doomscrolling habits makes for more "well behaved" children in public settings.
chatGPT is but one of the many symptoms, the root problem is that children should really have no business having unsupervised internet access.
