Even before LLMs, there was a _lot_ of deception and cheating in university. I -- and I do not say this with pride -- used to write essays for my classmates for money. In my own defense, I needed the money. I also know that in addition to homework for money, many fraternities and sororities kept copies of prior exams and assignments, and getting access to these was one of the perks of membership. Knowing what kind of questions to expect (let alone the exact questions) can easily give someone a few extra IQ points for free.
Personally, I felt that the drive to automate the parts of the professors' workloads that mattered (i.e. teaching and grading and evaluation and research), only so that they can be given work that matters less the more they do it (i.e. publishing slightly different flavors of the same paper, to meet KPIs), was oddly perverse.
The multiple-choice test and the puzzle-solving test and really any standardized test can be exploited by any group that is sufficiently organized. This is also true in corporate interviewing where corporations think (or pretend) that they are interviewing an individual, whereas they are actually interviewing a _network_ of candidates who share details about the interviewers and the questions. I know people who got rejected in spite of getting all the interview questions correct (the theory is that nobody can do that well, so they must have had help from previously rejected/accepted candidates).
The word "trust" shares a root with the word "tree" and "truth" and "druid". Most exams and interviews are trying to speed-run trust-building (note that "verification" is from the latin word that means "true"). If trust and truth are analogous to "tree", then we are trying to speed-run the growth of a tree -- much like the orange tree, in the film, _The Illusionist_. And like the orange tree, it is a near-complete illusion, a ritual meant to keep the legal department and HR department happy.
The LLMs have simply made the corruption of academia accessible to _all_ students with an internet connection (EDIT: and instantaneous and cheap, unlike a human writer).
There has never been a shortcut to building trust. One cannot LLM their way into being a (metaphorical) druid.
I do not look forward to the Voight-Kampff tests that will come to dominate all aspects of online and asynchronous human interaction.
Note that, short of homework/classwork that _can't_ be gamed by an LLM (for some fundamental reason), even the high-quality honest students will be forced to cheat, so as to not be eclipsed by the actual low-quality cheating students[0].
I imagine that we may end up wrapping around to live in-person dialectics, as were standard in the time of Socrates and Parmenides[1]. If so, this should be fun.
[0]: If left unaddressed, we may see a bimodal distribution of great and terrible students graduating college, with those in between dropping out. If college is an attempt to categorize and rank a population, this would be a major fault in that mechanism.
[1]: Not to the exclusion of the other kinds of tests, writing is still important, critical even. But as a kind of verification-step, that should inform how much the academic community should trust the writing (I can imagine that all the writers here are experiencing stage-fright as they are reading these words).
