Because AI detectors suck and are the modern day equivalent of dowsing rods?
They’re circular. If the text is too predictable it was written by an LLM* but LLMs are designed to regurgitate the next word most commonly used by humans in any given context.
*AI is a complete misnomer for the hi-tech magic 8ball
As expected, they can’t be trusted. And the more AI evolves, the less likely AI content will be detectable IMO.
It will almost always be detectable if you just read what is written. Especially for academic work. It doesn’t know what a citation is, only what one looks like and where they appear. It can’t summarise a paper accurately. It’s easy to force laughably bad output by just asking the right sort of question.
The simplest approach for setting homework is to give them the LLM output and get them to check it for errors and omissions. LLMs can’t critique their own work and students probably learn more from chasing down errors than filling a blank sheet of paper for the sake of it.
Clearly the Founding Fathers were not advanced enough to have crafted the US Constitution unaided. It’s only reasonable to imagine that ancient aliens could have landed, given them an AI to assist them, and then departed with nobody the wiser.
I am certain we can find evidence of this if we dig hard enough.
