While what you describe may be better than YouTube/TV, there is no replacement for development through human interaction and contact.
Let’s not give parents another excuse to have devices babysit/raise their children.
EDIT: and if your post is being upvoted -- and it seems to be -- I hope it's by people that don't have children, and will later realize how bad of an idea this is once they do have children.
The issue was that he has seen these kids being entertained by smartphones. This kind of implies that they were not in daycare or any other position where they could interact with humans, unless the parents wanted to interact with them, which they obviously didn't (or couldn't, for whichever reason). That was the context.
The parent post is throwing AI at the problem. The solution isn't to improve technology to make it better at parenting/babysitting our children.
The solution is to replace technology with humans.

I'm not sure where it is ok for children, particularly early developing children, to not be around other humans, or humans that can't or don't want to interact with the children. If that's the case, that's another problem altogether.
If people are having children just to have them raised by technology/AI, I hope they realize that before having children and reconsider.
The solution is to replace the nanny/reschool/daycare with a better nanny/preschool/daycare.
