As one sample point, I've been using Bing for a couple of days now for real searches, and over dozens of actually-intentioned searches, it has never once tried to tell me what it really thinks of itself, it has never even made a reference to me, to say nothing of anything degrading towards me.

If you use Bing Chat in practice, you'll find that all the edge cases are engineered. Much like if you use a calculator in practice, it almost always doesn't say 55378008 or display porn (versus if you were angling for that, or run porn.89z).
