Scott McDaniel wrote A Heuristic Evaluation of the Usability of Infants:
“The infant does not conform to normal industry standards of night and day, and its natural language interface is woefully underdeveloped… Infants have only a single error message, which they use for every error. The user, therefore, is left to diagnose each error with relatively little information. The user must remember previous infant states to see if input is required, and the user must also independently check other routine parameters.”
