ChatGPT and the like are in a weird position at the moment. It's usually pretty clear that you have written it using an LLM, but it's hard to PROVE. And you need to be able to prove it (to some degree, which varies depending on the institution) to reliably count off for it, otherwise the student will challenge your finding that they cheated and the Honor Court (or administrator, or other equivalent) will tell you that you can't do that.
So, you can usually get away with it if there is not some way the professor/TA can prove it.
As things change, this will change, but that's the situation the author of the original article finds themself in, because it's the current situation.
We will never reduce all class sizes to under 10 people. Large R1 schools are not going to reduce their number of students by a factor of 10 or increase their hiring by a factor of 10.
It should also be noted that she doesn't have a degree in "performing," as far as I'm aware, she has a degree in "studying the culture" of break dancing. So, we (or at least any of us who haven't read her work) don't actually know if she's good at what her degree is in. We just know that she's not good at performing.
"Once the student has three peer-reviewed publications, they graduate."
That's not a standard at all. You usually can't graduate without at least one peer-reviewed publication, but beyond that, as far as number of publications goes, it varies a lot from institution to institution. The biggest standard is that you complete a dissertation and defend it.
You also have the issue with kids who take the bus to school. With dark mornings, kids sit by the road and wait for the bus. So they walk in the dark to the bus stop, then wait there for some indeterminate amount of time in the dark.
Getting darker earlier at night, there are two advantages for schoolkids. One is that school tends to get out before the sun goes down even on the shortest days for most areas. So, many kids who'd have to wait in the dark in the morning don't have to deal with the dark at all in the afternoon. The other is that even when it's getting dark by the time the kid gets home, they don't have to wait next to the road for an indeterminate amount of time until the bus gets there.
To be clear, if it's a public figure, then just getting the fact checking wrong is not enough to be defamation. There has to be "actual malice" which BASICALLY just means they knew they were wrong or should have known they were wrong. If they can show that they were just following the information that was publicly available then they can make mistakes without losing a lawsuit.
Quater also means multiply by 4. I think they were pointing out that in the same post where you were criticizing them for what was pretty clearly a typo ("forth" instead of "fourth") you also made a typo ("quater" instead of "quarter") that changed the meaning.
So, you can usually get away with it if there is not some way the professor/TA can prove it.
