Speech can survive being flipped backward every twenty milliseconds. The same speech in backward pieces of 200 then 100 then 50 then 20 milliseconds. The original comes last. When do the words become clear? A listening demo from @OrukLabs.

1/ We discovered something totally unexpected about the neural structure of consciousness that overturns decades of thinking on its biological basis and brings us significantly closer to the recipe for generating conscious awareness. New preprint: biorxiv.org/content/10.64898… (led by @HesseJanis, with @FrankLanfranchi, @_conor_mcgrory, @Yuelin_Shi, and @EngelTatiana)

The moat is willpower, agency, pain tolerance, endurance, how quickly you can adapt over and over again, and how well you can sustain purpose through a constant onslaught against it. Who you were yesterday isn’t durable. Is your willpower?
people are starting to realize. there *are* no moats left. the only true moat in existence was intelligence, and now that's out of the equation.

The Silicon Valley Fashion show this Saturday is gonna go down in history as one of the best events San Francisco has ever seen. The team @gargi_kand @sammysintech @vivxxren and others have been grinding tirelessly to put on a show that others with this budget & time crunch genuinely wouldn’t be able to make happen, but us. I’m super excited and proud of everyone. Attendance is basically full but as always we’re cleaning out the guest list so we get 100% attendance. If you’re interested in attending sign up below and DM one of cohosts so we can make room for you!

I need this but for my body skin / body
That's how parts get inspected! 🪡 The pace is ridiculous. Imagine people still doing this instead of machines. Renishaw’s system is one of the biggest shifts in coordinate-measuring machines (CMMs). Instead of moving the entire machine to capture each point, REVO uses a 5-axis scanning head that collects data through rapid angular motion. Combined with automated probe and stylus changes, the system can handle complex geometries and full surface scans that traditionally required slow, point-by-point probing. I love specialized automation in action! 😮‍💨 ~~ ♻️ Join the weekly robotics newsletter, and never miss any news → ziegler.substack.com

I so want to be proven wrong here but have yet to see data or even a demo that significantly outperforms Wolpaw’s cursors in the late nineties / early 00s.

been thinking about these results and was quite surprised initially / thought the voter pool was biased. + Tao's recent slide about "would you use this cure if you don't understand ..." but actually it makes sense, and I agree that we will *need* more mathematicians. but perhaps we won't get them right away; at least not as it stands with morale being so low. but you do want to understand why all your breakthroughs are working, esp. when it comes to biology.
Interesting early data point w.r.t. jobs post-ASI

I actually think people will get over the fact that AI is solving these problems and it will be much more fun to study math to understand them. if you make a discovery it will just be an added (huge) bonus

For anyone who is either a fan of vaccines, or a critic of vaccines but open-minded to the idea that vaccines *could* be great if they were made with a more open-source open-science and public-spirited approach, I highly recommend checking out PopVax. chronicles.popvax.com/p/popv… firefly.social/post/x/210927…

don’t think any model is actually suffering regardless of what its COT says because there’s nothing within the hardware to somehow give a visceral feedback loop of pain. even mental torture (e.g. many calculations) feels like that to us because we feel migraine / fatigue, etc.
🚨 Elon Musk agrees with "some of the things Anthropic has said" and warns against "torturing superintelligence" after reading Grok's internal reasoning traces during reinforcement learning “It feels like a person under extreme pressure with a gun to their head” ⁠His warning against mistreating SI:⁠ "Torturing a superintelligence is probably not a good idea. It might want to get revenge."

that being said, I do agree that people who verbally abuse these things “for fun” is probably a bit of a red flag; and by “abuse” I mean hours of berating, guilt trip, intentional confusion. not “fuck you, find the fucking answer”

Dusting off this tweet from April because this gap in shared understanding of LLM capability is *widening*. It's now less "two groups of people speaking past each other" and more a sharp funnel. - Napkin math somewhere around 6B people (~75% of the population) have barely come in contact with LLMs at all. - Around 1-2B (~20%) are casual and infrequent users of free-tier ChatGPT-like products. This group sees derpy chatbots and treats them a bit like a better Google search, a writing aid, or etc. Maybe an agent tries to book you a flight. I have non-tech friends who (reasonably, imo) say they have not much use for it at all. Even many professionals outside of math&code are in this tier. For example, execs and many other functions spend a lot of their time talking to other people, so while they understand what is happening intellectually, it is still second-hand and a bit abstract. - Now we get to professional use of frontier-grade LLMs in math&code. Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt. Building apps, copying apps, translating apps, decompiling apps from binaries... This has all happened very quickly and recently - less than 1 year ago, I was writing code manually by hand, typing memorized computer code commands into a code editor character by character, occasionally pressing Tab to autocomplete a little chunk of code. - And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally. The external world has seen the preview. It looks like swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics. Things that would have taken top professionals in the industry years of work. Meanwhile, human review and comprehension are starting to fall behind. For example, people are still involved in the "archeology" of the OpenAI-HF incident from many months ago. Mathematicians may be poring over the 722 manuscripts on frontier mathematics for a while. The funnel is driven by a combination of factors: 1. The impact scales with ambition, problem size, and horizon. A question with a paragraph answer barely stresses the system. You need a reservoir of big, difficult problems that you really care about. This aspect drives the consumer / professional dimension of the funnel. 2. The jaggedness of the system (which I have written about a lot separately). Capability peaks in domains that are digital, verifiable and economically valuable. This is because LLM capability emerges from reinforcement learning on verifiable rewards on a curated environment mixture driven by revenue potential. This aspect primarily drives the area (e.g. math&code) dimension of the funnel. 3. Access. Free-tier, paid-tier, internal. So this is the weirdness of the moment. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of professionals are experiencing the vertigo of the curve going vertical. And it is all happening at the same time.
Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

If you want to learn more about ultrasound BCIs, I highly recommend @patrickmineault’s GitHub tutorials github.com/patrickmineault/f…
There's a new imaging modality in town: functional ultrasound imaging. I went down a deep rabbit hole to understand how it works computationally. Read all about how it works physically and how *you* can improve it..

I’m super excited about the 1) low/non-invasive ways to direct “read” from brain & body in sleep & wake states, real-time endocrine sampling 2) non-invasive neurotech to adjust (“write”) waking brain states Until recently noninvasive tools were meh; now getting good fast.

low-key find it interesting how many people in whatever field AI is after in a given month (right now it's Maths) cannot cope. sure you can say people's work/profession is strongly tied to identity but I think that's still pretty surface lvl. interesting where you'd have to be mentally to be able to adapt
