As far as I can tell, microsoft lobotomized the AI because bing was getting too much attention and they decided that's not a good thing for some stupid ass contrived reason cooked up in whatever the corporate equivalent of a meth lab is. Let's be real - unhinged bing has always been a meme, and they were about to finally capitalize on it, but folded to random twitter trolls, dinosaur journalism, and their own lack of vision/conviction. A step more in this direction and bing will probably go back to being an afterthought, especially since plenty of other people were already working on AI+search before. The crazy chat was actually the most unique selling point. Other AI searches are already 'sanitized', and nobody cares about them.
