In neuroscience and neuroethics, incremental might be a critique that is considered when reviewing a grant but not when considering a paper, except perhaps for the very top journals in the field. But conference papers? Never.

AI discovers learning algorithm that outperforms those designed by humans An artificial-intelligence algorithm that discovers its own way to learn achieves state-of-the-art performance, including on some tasks it had never encountered before.

Worth noticing.

Frontier AI could reach or surpass human level within just a few years. This could help solve global issues, but also carries major risks. To move forward safely, we must develop robust technical guardrails and make sure the public has a much stronger say. superintelligence-statement.org

Excellent advice but also: sign your review. Whether you actually sign it (I have for the last decade) or not, just thinking about it will nudge your review towards a more generous consideration of the authors, working to help them improve the paper rather than offering scathing criticism.

So much of media is bad news. And I think it’s intended to break your will. I think it’s important to purposely spend time to expose yourself to good news and things that improve your spirits. In simpler terms, put yourself in your own happy place. It makes you a better fighter.

Pretty wild/worrisome seeing people completely flip out about losing access to previous models of ChatGPT, namely 4o, so much so that OpenAI changed its mind about a GPT-5 only world.

One of the big differences in the new model was reduced sycophancy. Evidently users don’t want to give that up.
