    As a former materials physicist, I am genuinely unsure of what to make of this superconductivity paper. 🧵 👇

    Last year, Sam Bankman-Fried scammed me into writing an essay, by dangling a $1.5M essay contest that disappeared along with FTX. My loss is your gain. We just published 114 pages on why we think transformative* AGI in the next 20 years is <1% likely.

    Transformative AGI by 2043 is <1% likely
    This paper is a submission to the Open Philanthropy AI Worldviews Contest. In it, we estimate the likelihood of transformative artificial general intelligence (AGI) by 2043 and find it to be <1%. ...

    Just dropped: updated guide for Q&A with GPT and embeddings-based search. Discusses: - Why search is better than fine-tuning - What types of questions this fails on - How to troubleshoot & improve your system If you have ideas to improve, I'll do them.

    In favor: the scientists look legit, the graphs look legit, the materials system looks legit (related to cuprates), the video shows one sample halfway levitating, and, most speculatively, they just published a three-author hype paper (Nobel prize maxes out at 3 winners per).

    Against: They didn’t even measure a Tc (because their PPMS maxed out at 400 K and apparently they didn’t bother to use an oven??), they relatedly didn’t measure a Meissner effect, and they published this three months ago with little fanfare. Can fear of scooping explain this?

    This paper examines the way of thinking and limitations of physicists regarding the phenomenon of superconductivity and outlines how room-temperature and ambient-pressure superconductors can be developed through the statistical thermodynamic background of the liquid state theory.

    Lastly, if you had discovered room-temperature ambient-pressure superconductivity, would this really be the first sentence of your paper:

    *in hindsight, not actually sure how related to cuprates this material is. i was just comforted by the stalwart copper and oxygen in the chemical formula. i’ve been out of the complex oxides game for a while now (although i did write the wikipedia article on the subject).

    update: my best guess at this point is that the measurements are real but misinterpreted. maybe a metal-insulator transition/breakdown in a normally diamagnetic insulator. would really love to see meissner effect measurements etc. that don't rely on bulk conductivity measurements

    Like, really? In any case, I’m curious to see where this all goes. April paper: koreascience.or.kr/article/JAKO20…

    paper probably isn’t correct, but you can probably make the same arguments about high Tc superconductors or blue LEDs. a lot of geniuses toiling for years by baking powders in ovens. the combinatorial recipe space is huge, and it can take weeks or months per material.

    Jotted down a list of some interesting prompting libraries and prompting papers in a new section of the OpenAI Cookbook. Any ones you like that we're still missing?

    AGI is hard to define. my preferred definition of AGI is a computer system that can can accomplish a task impossible for 100 human geniuses working together, such as publishing a blog post with a single canonical spelling of GPT-4o / gpt-4o / gpt4o
