Most people have friends and family to "glaze" them anyway. I don't see it as a major danger. Also, it's gotten better with the glazing lately anyway.

The danger is in the replacement. Confiding in others builds a web of trust. Talking about a break-up with a friend builds a relationship, and the next time that friend needs someone, they know you're an option. It's economics, borrowing and trading emotional support. AI as confidant destroys that economy.
