Also, the idea of using it for reassurance reminds me very hilariously of the AI companion teddy bear in 'Super Toys Last All Summer Long' (found https://www.wired.com/1997/01/ffsupertoys/)

A very topical quote. "Teddy" is the AI reassurance bear, David is the little boy.

"I'm no good, Teddy. Let's run away!"
"You're a very good boy. Your Mummy loves you."
Slowly, he shook his head. "If she loved me, then why can't I talk to her?"
"You're being silly, David. Mummy's lonely. That's why she had you."
"She's got Daddy. I've got nobody 'cept you, and I'm lonely."
Teddy gave him a friendly cuff over the head. "If you feel so bad, you'd better go to the psychiatrist again."

! Hahaha.
