TFA's case involved examinations about the student's submitted project work. It's not the same thing. Even for a more traditional examination with no such context attached one might still want to rely on AI for grading. (Yeah, I know, that comes across as "the students are not allowed to use AI for cheating, but the profs are!".)

Also, IMO oral examinations are quite powerful for detecting who is prepared and who isn't. On the down side they also help the extroverts and the confident, and you have to be careful about preventing a bias towards those.

This is true, but it is also why it is important to get an actual expert to proctor the exam. Having confidence is good and should be a plus, but if you are confident about a point that the examiner knows is completely incorrect, you may possibly put yourself in an inescapable hole, as it will be very difficult to ascertain that you actually know the other parts you were confident (much less unconfident) in.

You could argue that for fields like law, medicine and management extroversion and confidence are important qualities.
