Back in the spring, Microsoft Japan started Twitter and Line accounts for Rinna, an AI program the company developed and gave the personality of a high school girl. She quickly acted the part of an online teen, making fun of her creators (the closest thing AI has to uncool parents) and snickering with us about poop jokes.
Unfortunately, it looks like Rinna has progressed beyond surliness and crude humor, and has now fallen into a deep, suicidal depression.
I smell a rat here :p. It might be a publicity thing, because it was very recently when Microsoft USA had an AI agent turn in to a racist. The creators are very likely to have added safeguards to cover that. Most likely this is intentional, for the purpose of research, publicity, data collection, whatever.
I heard about the first bot but somehow I missed the obvious link, in my mind I didn't link Microsoft US and Japan bot. Even thoug the research (and marketing!) teams are obviously connected so you must be right!
