I think certain models are really good at mirroring and relationship building, and at a certain point people bifurcate. Some continue falling in deeper, while other people develop an ick.

I remember an AI conversation with Opus 4.6 in which I almost forgot I was talking to AI. I felt happy, warm and comfortable and then I kinda snapped out of it and felt really gross all of a sudden.

Since then, that feeling has stuck with me. I now use it much more like a tool and I keep my guard up.
