AI Detection is genuine BS

I'm so sick off it academic institutions might as well scrap essays if they cant even trust it's you're own work.

There is no University anywhere which says you cannot use AI to aid you in your studies.
What Universities do not permit is people submitting work an AI has generated and then claiming it as their own work. That is academic misconduct. It won't fly in the commercial nor scientific world and it sure as heck won't fly in academia so you might as well get used to it now.

I think the point he's making is that there is a culture of paranoia in most schools on the topic of AI and cheating. I've read numerous accounts of students being accused of cheating by teachers and, as it turns out, teachers aren't very good at this (Fleckenstein et al., 2024). I really think we're in need of a total restructure of assignments/testing and schools like Newlane are paving the way.

It's not up to teachers to spot academic misconduct, they use turnitin. Outside of that, if some genius wants to use AI to make themselves appear clever, the joke is on them: it won't work in an examination hall.

turnitin is an using AI to catch out AI is comical half the time it's not accurate I've found AI seems to only recognise dumbed down sentences as Human written meanwhile the use of common adverbs will commonly flag a sentence as AI written ran one of my IT assignments from year 8 (2018) and it came up as potentially AI written I can't take it seriously.

I'm not here to argue, but turnitin is pretty sensitive and anyone submitting work that is dubious had better be aware of it.
The best way to avoid coming to grief is in not using AI to create your work. Use your own words and play within the rules of the game.
Lecturers and teachers aren't daft: a lot of them are experts in their own respective fields and they will know a lot about the content you write about and possibly even be familiar with any references you use.
You just cannot pass work off an AI created and call it your own. It's academic dishonesty, pure and simple. It on won't fly in the world of academia so you may as well accept it and move on.

Bro what my grief is the hoops I have to jump through to ensure I dont get my work referred back to me for "AI plagiarism" despite not using AI it's pretty funny you jumped to the conclusion that I'm moaning about not being able to pass off AI as my own work.

Unfortunately not. The instructor makes the first and final determination. For example, there are many redundant flags for AI detection and turnitin will respond accordingly. An instructor will make the decision to either ignore or escalate based on many factors such as the past performance of the student and so on. Additionally, if an instructor is convinced something is awry they can apparently subject the assignment to additional AI detection outside of turnitin or, that's what many students are reporting. Either way, the instructor/teacher does in fact play a core role in this context.
