in a way i'm not sure why there is still no parents or students complaining they're kind of being 'defrauded' for a chatbot while paying high tuition (cue discover card tv ad.) one thing for sure is that there are a lot of undergrad or grad students around looking for a part-time job and teaching experience. i know this is a great achievement in AI with huge potential in open course, and great for grant application, but on the very other end is someone paying with an expectation of a human interaction & care. for years i've seen a lot of complaints about foreign human TAs.
