Hire Natalie right now! She's amazing
And now might be a good time to mention, I’m on the faculty job market this year! I do work in human-AI collusion, collaboration and competition, with an eye towards building foundations for trustworthy AI. Check out more info on my website here! Nataliecollina.com

hate to say told you so
When I asked Bluesky users why they left X, many said they didn’t want their posts training AI.
But with Bluesky’s open API, anyone can scrape posts for that purpose. A HuggingFace employee just shared a dataset of 1M posts.
The reality: if you post online, assume it’ll be used to train AI.
