Comment More Distracting Than Convincing (Score 3, Interesting) 132
Watching his video left me more distracted than informed.
Instead of thinking about academic integrity, I kept noticing everything around the story. As a European, hearing someone who tags himself as "#professor" say "y'all" while trying to make a serious point, with piano music playing underneath, already made the whole thing feel oddly staged. Then my first reaction to hearing '32 students failed because they used AI' was actually: wait, didn't 32 students correctly follow the assignment? If the hidden instruction says to put the word "Madagascar" somewhere nonsensical, then anyone who actually saw that instruction would do exactly that. I probably would have too, because my first instinct is to paste assignment text into a plain text editor before working on it, which would likely reveal hidden white text.
Then I noticed the hidden instruction itself contains an opening quote before "Madagascar" but no closing quote. That typo immediately jumped out at me, which made it a little ironic given how much emphasis the professor places on proofreading.
There are also alternative explanations that never get discussed. Depending on the software or accessibility settings (some commenters mentioned dark mode), hidden white text might not actually stay hidden. If students were allowed to contest their grades, that's good, but it also suggests the presence of "Madagascar" alone wasn't necessarily conclusive.
The hidden-text trick is clever as a way of catching one particular copy-and-paste AI workflow. But after watching the video, I came away thinking less about AI cheating and more about all the assumptions, presentation choices, and edge cases surrounding the demonstration. I left more confused than convinced that I'd just seen a particularly strong piece of evidence.
