🚨 New study!
We tested whether AI-generated messages – single static messages vs. conversations – can boost intent to screen for colorectal cancer.

Turns out: short, tailored AI messages outperform expert-written materials & match conversations, at a fraction of the time! 🧵👇

I was curious how that compared to the ARR round for ACL this year (Feb 2025) and the number of subs was 8.3K, all time high. I wonder what drives this: increased interest in the field, AI-generated papers, ... What do you think?

Why did Grok suddenly start talking about “white genocide in South Africa” even if asked about baseball or cute dogs?

Because someone at Musk’s xAi deliberately did this, and we only found out because they were clumsy.

Many feel that politics globally has become toxic and hostile over recent years.

But is this actually the case? And if so, who's to blame? What issues are driving toxicity?

Remarkable assessment by an incoming German chancellor. “for me it is an absolute priority to strengthen Europe as quickly as possible, so that we achieve independence from the US, step by step.” www.dw.com/en/german-el...

Exclusive: US could cut Ukraine's access to Starlink internet services over minerals, say sources U.S. negotiators pressing Kyiv for access to Ukraine's critical minerals have raised the possibility of cutting the country's access to Elon Musk's vital Starlink satellite internet system, three sources familiar with the matter told Reuters.

"During the meeting, Ukraine was told it faced imminent shutoff of the Starlink service if it did not reach a deal on critical minerals, said the source, who requested anonymity to discuss closed negotiations."

Astonishing betrayal of an ally.

It says on OpenReview that the deadline is Feb 24 2025 12:00AM UTC-0, is that normal? Thanks a lot for organizing!

Nazi on a screen

The US Oligarch and Nazi Elon Musk has been defeated by a German court.

Germany has ruled that Musk must immediately provide researchers with access to X's data on politically related content ahead of the country’s election.

Zuck cut moderation b/c he said people no longer want it. But he's wrong!
We polled 1k Americans and most people, including majority of Reps:
i) want content moderation
ii) don't want Community Notes w/o fact-checkers
