"The oral system scales poorly. One examiner can only hear so many students in a day."

I'm not joking: you could have an AI quiz the students and test their understanding. That way the tests go deeper into testing the understanding by following through on the answers, and are standardized and fair for everyone. I don't think we are there yet at all but I actually think its not insane for the future. I expect downvotes though/I don't think our generation would agree with this.

What's old is new :)
