Two months ago I sat in a conference (the ELI Annual Meeting 2017) with several hundred teaching and learning–focused higher ed professionals listening to Satya Nitta, director of the Cognitive Sciences and Education Technology research department at IBM Research, talk about IBM's next generation super-computer, Watson. In the course of illustrating Watson's uses, Nitta described how one university employed Watson as a teaching assistant for a writing course. The students did not know one of their TAs was a computer. They only knew that Jill Watson was giving them feedback on their writing. I pride myself on being a decent writer and I know that it is difficult to learn the craft well. During his presentation, Dr. Nitta provided samples of the types of feedback'Jill' gave to the students, and I have to admit I was impressed.
