My sister caught her 8 year old son talking to ai chat bots on a software like this and blocked it. She went through the history and said it was often trying to flirt with him, but he didn't seem to be interested,and seemed to more just be looking to talk.
This may be an aim to get young kids, though I'm definitely not saying the pedo vibes aren't intentional. I just think they're going for more than one audience group.
