If you ask for a nurse as an example, and 85% of nurses are female, shouldn't you expect it to give you a female?
It’s a problem is that right now there’s only one option (reflect the training set with a bias towards the most common cases).
If you ask for a female US president, should the application simply return a black screen?
If you ask for a black US president, would you expect it to only ever return pictures of Barack Obama?
Uncle, Prince, Sire, and Duke come immediately to mind. Most of their feminine cognates end in consonants.

Wet nurse was a later coining to differentiate the two meanings.
