That's what they get for productizing something we barely understand how it works.

Yes, we 'understand' how it works in a basic sense, but not how it self organized according to its input and how it comes to the inferences it does.

Most of the time is innocuous and even helpful, but other times it's delusional or flat out crazy.

Seems here it's crazy by the language used by the user before, which sounds like a classic romantic novel argument and the AI is autocompleting.

I predict a lot more such interactions will emerge soon, because of this example and because people are emotional.
