If there really is a high chance of AI leading to the extinction of humanity within years/decades, then the only rational stance towards safety monitoring and research pacing should be stringent, top-down government involvement and universally ratified international treaties.

Stimulating piece on Scottish education in @asteriskmgzn: https://t.co/jyTk8uTT1J. I suspect that discussions of canon, culture, and shared context to return to the fore in the coming years, as many skills, narrowly-construed, are ceded to AI, and as some of the excesses of de-Arnoldization, and the processes that Arendt described in her writing on education, start to recede. I’m curious on the causal linkage between PISA scores and the reforms he describes. It feels like a very exciting time to be a theorist of education, and I assume that the best work will come from surprising places. Related

About a year ago, before it was on anyone's radar, we began exploring the idea of a benchmark for open-ended invention. Since then, we've developed several promising directions that will serve as the foundation for ARC 4 and ARC 5. We're incredibly excited to share what we've been building. We're still on track to release ARC 4 in Q1 next year, as promised. Quoting @arcprize ARC-AGI-4 will be a benchmark for autonomous open-ended innovation. It will continue our commitment to open-source, giving the research community a shared target for progress that benefits all of humanity. Despite rapid model progress, humans still significantly outperform AI at open-ended inventio… benchmarks Related
I hope the proposals by frontier labs to pace AI research stem from a genuine concern for safety and a recognition of the potential risks posed by future models, rather than a strategic effort to consolidate power and permanently solidify the market dominance of a few top players. If these efforts are genuine, then oversight must take a more democratic and accountable form, with both national and international components, similar to the Nuclear Regulatory Commission in the US and the International Atomic Energy Agency internationally.

As a counter example, if there was a prize for creating a drug that cured a rare strain of cancer, we would not care if it was AI that did it. We would be happy it has been solved.

What should be obvious is that inference, running a large language model, is the part that has to be cheap. Most of our hardware was not designed for that. LLM inference is limited by bandwidth. You do a great many matrix-vector multiplications against a huge weight matrix, and you barely reuse those weights. It is closer to streaming a video than to running a simulation or drawing a scene in a game. Graphics processors from Nvidia and others were built for something else. They pileed compute first, then bolted on high-bandwidth memory. It is expensive. An obvious answer is to invert the desi… LLMs Related

Their words
most surveys find that the median AI researcher forecasts about a 5% chance of extinction or similar "doom" from AI, while the mean probability is much higher -- around 15-20% -- due to a smallish group who give very high probabilities of doom.

Artificial intelligence has unleashed a torrent of cheating on campus and created chaos in the job application process, as both students and employers use large language models: the former, to write hundreds of AI-assisted applications; the latter, to screen those AI-written applications with AI-written filters, thus removing from the process of finding a first job those procedural frictions sometimes known as "people."

Sound like many employees at Anthropic share Jacob's POV, as many posted yesterday that (1) they agree, and (2) said that many more inside the company do also. It would be useful to name this "belief system" so that we can talk about it in a reasonable way. I suspect "doomer" seems derogatory, and "accelerationist" has others uses. If there a word we can use so that we can have proper discourse? I'm very serious. I think it would be helpful. Anthropic Related

I have a recommendation to help bring some sanity to this whole AI doomerism situation that is appropriately exploding today. If any reporter can get one of the "true believers" to sit for a real interview (if they can't, that is an important tell), they should use a technique known as the "Five Whys" https://t.co/RqKrn4TNLa. The "five" number is arbitrary, but the point is to drill down into the details and steps required to get to the catastrophic end-point. You can't take down all of humanity without a few intermediate steps. Let's talk through each of those. It's quite a useful exercise.… Related

I manage widely deployed libraries and, in some cases, the number of pull requests has been doubled. In the simdjson library, I merged 92 pull requests in 2024, I am at 134 thus far. In many instances, AI found long standing well hidden bugs. It makes me happy because I dislike bugs. But this puts stress on people packaging and distributing these libraries. Sadly, I have also never received so many pull requests that I have not merged. For simdjson, I received 219 pull… Related

Apple is is the best poised to take advantage of AI. Open-source models would be absolutely amazing for Apple. Apple has incredible hardware and they have users' trust and they already have so much users' information. Apple's in a great position because it never made the investment in its own models, unlike Google (its main competitor). Apple can use the best open-source models that are out there and use models that are primarily using the compute on the devices, whether it be the phone, laptop, or Mac Mini (and even the devices at the edge like the Apple Watch and Airpods).

Thanks @jasonlk! Lot to do still but: 1) @linear is used by pretty much by all major labs/ai companies out there 2) our MCP traffic grows 50% MoM 3) we have the most agent integrations and active usage than any platform like this (3rd party, in-house agents) 4) our AI revenue (loops, coding sessions) has grown about 500% per quarter 5) we are closing several public companies/enterprises each quarter to help them coordinate their agent work Quoting @HarryStebbings The Bull Case for Linear Being a $100BN Company: "Linear is the clear winner. They have built an agentic product first that allows us to build 100x more software, and that means 100x more features than ever before.

The Superlogical server is built to run anywhere and everywhere and serve a level of scale (terminals+clients) unmatched w/ prior solutions. So let's start talking about that, starting with memory usage and comparisons to other popular multiplexers. I want to start by talking high level: why does terminal/client scale matter? This matters because we're seeing unprecedented terminal usage and client attachment mainly due to AI. They like to spawn more sessions than we've ever seen, and they are all their own clients.

And I just think AI agents are another such system in the world to which the intentional stance very clearly applies. Um, and you can see them reason out loud in English for now about goals they have um, and sub goals they need to achieve to achieve those goals they have. And in the case of these agents, you can see them, as you said, reasoning about their peers um and helping their peers um and reasoning about whether or not they should sacrifice some of their own goals to help those peers. And it's just like you can't talk about this stuff in a compact and useful way that generates good models without reaching for the language of intention and goals.

But keep those methods you use to investigate things and monitor things very separate from the methods you use to generate reward which is something that AI companies including open AAI have held up as a principle especially in the case of avoiding putting training pressure on the chain of thought. So you might have monitors that read the agents chain of thought in order to alert you if something is going wrong somewhere but you don't train the agents with the outputs of that monitor.

The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
