| something on the internet without much thought.
|
| Now that LLMs are both useful and well known, the temptation to
| cheat with them is huge. For various reasons I think students and
| applicants see using LLMs as not-cheating in the same situations
| where they wouldn't feel comfortable copying answers from a
| friend. The idea is that the LLM is an available tool and
| therefore they should be able to use it. The obvious problem with
| that argument is that we're not testing students or applicants on
| their abilities to use an LLM, we're using synthetic problems to
| explore their own skills and communication.
|
| Even some of the hiring managers I know who went all in on

| Yes, obviously this won't work for deaf students. But why must it
| be an oral examination anyways? In the real world (see above
| example) you can't cheat at an oral examination because you're
| physically present, with no cheat sheets, just you, and you have

| so they had to add a requirement of audio/video recording to
| restore the value of the "physically present" part of old-school
| oral exams -- if you could do something like that for written
| exams, surely you would?
|
| Clearly a take-home written exam would be prone to cheating even
| with a real-time AI examiner, but the real-time requirement might
| be good enough in many cases, and probably always for in-class
| exams.
|
| Oh, that brings me to: TFA does not explicitly say it, but it
| strongly implies that these oral exams were take-at-home exams!
| This is a very important detail. Obviously the students couldn't
| do concurrent oral exams in class, not unless they were all

| have been in school facilities with one student present at a
| time, but that would have taken a lot of time and would not have
| required that the student provide webcam+audio recordings -- the
| school would have performed those recordings themselves.
|
| My bottom-line take: you can have a per-student AI examiner, and
