I take your point. It’s just that any scenario you’re describing with so-called AI could have been done by a search engine already. The slop of yesteryear was SEO ranking articles and fake links to make the algorithm prioritize your site over others. Well poisoning is how PR agencies get troublesome celebs out of the headlines again. The list goes on.
I share your concerns about the black boxed nature of so-called AI and by extension their search engines. I’m not saying it isn’t a problem; it’s just not a new one. Up until now we have had companies in charge with a vested interest not to bend the flow of information too far from, let’s call it, the median truth. Now companies are letting models make these decisions and some humans afford these models more credibility than their common sense and that is all worrying to say the least. So I’m a worried as you are, it just started earlier for me.
I don’t think you did anything wrong. I hate people striking up a conversation like that as well.
You can train yourself not to panic, deep breaths, focusing on something in the middle distance, closing your eyes, counting to ten - whatever works for you. And then you can ride a situation like this out. Either by masking your discomfort or giving very curt replies. You can also just say “I’m very sorry, I’m not in the mood for a chat.” But you mustn’t worry that you made an extrovert sad. She’ll get over it and maybe learn from this experience as well.
