We see a similar effect in edits, although not statistically significant. Very important to keep monitoring in the future, as platforms like Wiki serve as important info repositories (and training data for future LLMs)

This is in contrast to prior work that sees no significant change to Wikipedia articles *as a whole*, after the launch of ChatGPT. This masks selective changes in consumption patterns.

Curious to see what analyses you do! I've been tracking my habits and moods on Daylio for the last 2 years for no reason but to one day do some data analysis on myself... maybe that day will come soon

Come work with people like @dholtz.bsky.social, Nicola Rosaia, and me :)

Terrifying how much control the Trump administration has on our education system...

I definitely believe these trends are happening, but I can't figure out how they would reliably measure this? Their method relies on classifying which texts are AI generated, and so the classifier could just be flagging texts with low diversity

Yes to evaluating the *outcomes* of these systems rather than as a standalone algorithm! This is something that's been bothering me for a while about ML assisted decisions

Hmm what are you suggesting to divide by?
