Should your children's teachers be able to use AI to grade student work?

We have talked before about whether students should be able to use AI apps, such as ChatGPT, to help them do their homework. Opinions were mixed. Now we hear that some teachers are using ChatGPT to grade student work. Should they be able to do so?
 
This one hits a little close to home for me as I've witnessed my twin 12-year-olds "leveraging" ChatGPT with schoolwork. I welcome your comments on both students and teachers use of ChapGPT!
