I don't know why I have such a visceral gut turning reaction to the idea of a bodyless voice synthesizing a bedtime story to a child. I don't have children, but always thought the whole bedtime story thing was meant to be time spent with the parent.
I've played around with chatgpt telling stories to my kids, but they don't like it that much. The stories aren't very good, and they're trite and predictable -- even with 4o. It's really only interesting to them at all because it's choose your own adventure.
In a perfect world, yes. In the real world, some nights the parents are not able to read/tell the story. The children don't care, they want the story anyway.
