I'm so sorry I can't stop laughing. OpenAI, the company built on stealing literally the entire internet, is crying because DeepSeek may have trained on the outputs from ChatGPT. They're crying their eyes out. What a bunch of hypocritical little babies. Cry more, freaks.

Unsolicited advice to authors:
In your responses to reviewers, the best practice is to respond point by point, using the same numbering and even including the reviewers' comments verbatim directly before each response.
Do not remove the numbering, jumble the order, and paraphrase the comments!

EUROPE IS DOING FINE. Look at these trade figures from Hélène Rey (London Business School and CEPR) which she presented in her prize talk at the 3rd Kiel-CEPR Conference on Geoeconomics this past autumn. In an equalising world, CN = US < EU

People, just stop doing Frontiers special issues. Find a nice diamond open access journal, and self-publish and collaboratively peer review the set of papers you all want to write. Do not give Frontiers money. They add no value. If anything, they hurt your reputation. MDPI is of course even worse.

I wonder if people like Mark Zuckerberg and Jeff Bezos use AI themselves or if they know its dangers and steer clear, considering it only for their underlings.

Kind of like a drug dealer: you don't get high on your own supply.

I wish cars would just do what I expect and follow traffic patterns. No, I'm not going to turn left across the street in front of you while you are unexpectedly stopped and waving for me to bike across and I can see a line of cars building up behind you getting grumpier and grumpier.

Just saw Heretic. Was about 2/3rds of a movie in terms of storyline. Not much character development. The acting was great, though.

Yes AND I personally would like those academics to also engage with the ways in which LLMs are "plagiarism machines" [1], and to reflect on their attitudes towards plagiarism in scholarly work, the classroom, and the academy generally.

*sighs*

Percentage change should *always* be expressed on a log scale, because it’s multiplicative.

A doubling and a halving should be given equal space.
