• Blur tool for photographs

    Ted Chiang’s post on The New Yorker about how ChatGPT—an LLMs in general—are the blurry JPEG of the web. This post is old and came out in Feb’23.

    When an image program is displaying a photo and has to reconstruct a pixel that was lost during the compression process, it looks at the nearby pixels and calculates the average. This is what ChatGPT does when it’s prompted to describe, say, losing a sock in the dryer using the style of the Declaration of Independence: it is taking two points in “lexical space” and generating the text that would occupy the location between them. (“When in the Course of human events, it becomes necessary for one to separate his garments from their mates, in order to maintain the cleanliness and order thereof. . . .”) ChatGPT is so good at this form of interpolation that people find it entertaining: they’ve discovered a “blur” tool for paragraphs instead of photos, and are having a blast playing with it.

    Reminds me of Venkatesh Rao’s analogy on LLMs as index funds.

  • Revenge of the English majors

    Quoting Stephan H. Wissel.

    LLMs with their dependency on well crafted prompts feels like the revenge of the English majors hurled towards computer science

  • Vibe hacking

    Kevin Collier reporting for NBC News on how a hacker vibe hacked their way into various industries. This information comes from Anthropic’s Threat Intelligence Report for Aug’25.

    …one of Anthropic’s periodic reports on threats, the operation began with the hacker convincing Claude Code — Anthropic’s chatbot that specializes in “vibe coding,” or creating computer programming based on simple requests — to identify companies vulnerable to attack. Claude then created malicious software to actually steal sensitive information from the companies. Next, it organized the hacked files and analyzed them to both help determine what was sensitive and could be used to extort the victim companies.

    The chatbot then analyzed the companies’ hacked financial documents to help determine a realistic amount of bitcoin to demand in exchange for the hacker’s promise not to publish that material. It also wrote suggested extortion emails.

    The chatbot then analyzed the companies’ hacked financial documents to help determine a realistic amount of bitcoin to demand—What the…!

    Since I have started following AI news, I read about how you should break down your problem statement into smaller chunks for AI, setup a plan, do periodic reviews of code generated, and then accept the changes. I never thought this approach would be effective in hacking also.

  • Nuclear batteries

    Today I learned that we have something called nuclear batteries. For more than 50 years. James Blanchard talks about the genesis of these batteries, why don’t we use them anymore, what are its current applications, and more.

    In 1970, surgeons in Paris implanted the first nuclear-powered pacemaker, and over the next five years, at least 1,400 additional people received the devices, mostly in France and the United States. Encased in titanium, the batteries for these devices contained a radioactive isotope—typically about a tenth of a gram of plutonium-238—and could operate for decades without maintenance. The invention provided relief to a population of people who previously needed surgery every few years to change out their pacemaker’s chemical battery.

    Technically, they are not nuclear. They are radioisotopes.

    The term “nuclear batteries” may evoke images of tiny nuclear reactors, but that’s not how they work. Nuclear batteries don’t split atoms with neutron bombardment. Instead, they capture energy in the form of radiation that’s spontaneously released when atomic nuclei decay.

    Most research groups developing nuclear batteries are focused on harnessing energy from radioactive isotopes of nickel and hydrogen. In many nuclear battery designs, adjacent semiconductors absorb the radiation released by the radioisotopes’ nuclei and convert it to an electric current, much like a solar cell does. In other designs, thermoelectric devices convert the heat produced by the emitted radiation to electricity. So “radioisotope power source” is a better descriptor than “nuclear battery,” but for ease of language, I’ll use these terms interchangeably.

  • What if AI isn’t a bubble?

    Craig McCaskill gives multiple example of bubbles and how they ultimately burst. But what if AI isn’t a bubble? What if this is the real deal?

    The AI revolution is real, transformative, and probably unstoppable. Whether it unfolds through sustainable growth or boom-bust cycles depends largely on the choices we make in the next few years. The early signs (including voices like Altman’s warning about overexcitement) suggest we might actually be learning from history.

    The AI bubble’s human impact could be fundamentally different. Previous bubbles destroyed jobs when they burst. AI might destroy jobs while it’s still inflating. If AI actually delivers on its automation promises, we could see the first bubble that eliminates more employment during its rise than its fall.

    This creates an unprecedented social risk: a technology bubble that succeeds in its goals might cause more disruption than one that fails. The Railway Mania gave Britain train networks and industrial jobs. The dot-com bubble gave us e-commerce and digital careers. The AI bubble might give us unprecedented productivity and fewer jobs. That’s a social equation we haven’t solved.

  • AGI. Are we there yet? Part 2

    Dwarkesh Patel arguing why he doesn’t think AGI is right around the corner.

    But the fundamental problem is that LLMs don’t get better over time the way a human would. The lack of continual learning is a huge huge problem. The LLM baseline at many tasks might be higher than an average human’s. But there’s no way to give a model high level feedback. You’re stuck with the abilities you get out of the box. You can keep messing around with the system prompt. In practice this just doesn’t produce anything even close to the kind of learning and improvement that human employees experience.

    The reason humans are so useful is not mainly their raw intelligence. It’s their ability to build up context, interrogate their own failures, and pick up small improvements and efficiencies as they practice a task.

    How do you teach a kid to play a saxophone? You have her try to blow into one, listen to how it sounds, and adjust. Now imagine teaching saxophone this way instead: A student takes one attempt. The moment they make a mistake, you send them away and write detailed instructions about what went wrong. The next student reads your notes and tries to play Charlie Parker cold. When they fail, you refine the instructions for the next student.

    This just wouldn’t work. No matter how well honed your prompt is, no kid is just going to learn how to play saxophone from just reading your instructions. But this is the only modality we as users have to ‘teach’ LLMs anything.

  • Who’s making money in AI right now?

    Dave DeGraw ranting about his frustration with vibe coded PRs and asking the most important question.

    Is anyone making money on AI right now? I see a pipeline that looks like this:

    • “AI” is applied to some specific, existing area, and a company spins up around it because it’s so much more “efficient”
    • AI company gets funding from venture capitalists
    • AI company give funding to AI service providers such as OpenAI in the form of paying for usage credits
    • AI company evaporates

    This isn’t necessarily all that different than the existing VC pipeline, but the difference is that not even OpenAI is making money right now.

    Ha!

  • Acknowledge and repair

    Matheus Lima highlighting a lesser known—but important—skill for managers.

    Let me tell you something that will happen after you become a manager: you’re going to mess up. A lot. You’ll give feedback that lands wrong and crushes someone’s confidence. You’ll make a decision that seems logical but turns out to be completely misguided. You’ll forget that important thing you promised to do for someone on your team. You’ll lose your temper in a meeting when you should have stayed calm.

    The real question isn’t whether you’ll make mistakes; it’s what you do after.

    You acknowledge and repair. I can personally vouch for this.

  • Software engineering vs traditional engineering disciplines

    This comment from potatolicious on Hacker News about how AI has removed the deterministic expectations.

    …I was trained as a classical engineer (mechanical), but pretty much just write code these days. But I did have a past life as a not-SWE.

    Most classical engineering fields deal with probabilistic system components all of the time. In fact I’d go as far as to say that inability to deal with probabilistic components is disqualifying from many engineering endeavors.

    Process engineers for example have to account for human error rates. On a given production line with humans in a loop, the operators will sometimes screw up. Designing systems to detect these errors (which are highly probabilistic!), mitigate them, and reduce the occurrence rates of such errors is a huge part of the job.

    Likewise even for regular mechanical engineers, there are probabilistic variances in manufacturing tolerances. Your specs are always given with confidence intervals (this metal sheet is 1mm thick +- 0.05mm) because of this. All of the designs you work on specifically account for this (hence safety margins!). The ways in which these probabilities combine and interact is a serious field of study.

    Software engineering is unlike traditional engineering disciplines in that for most of its lifetime it’s had the luxury of purely deterministic expectations. This is not true in nearly every other type of engineering.

    If anything the advent of ML has introduced this element to software, and the ability to actually work with probabilistic outcomes is what separates those who are serious about this stuff vs. demoware hot air blowers.

  • Reverse and forward engineering with AI

    Birgitta Böckeler explaining how AI has changed reverse and forward engineering.

    I say AI-accelerated reverse engineering and then AI-accelerated forward engineering, where the reverse engineering only includes a description of the application, not actually building it, so the forensics kind of. You do forensics on the existing application and the existing code to recreate a good description of what it does. Because we can now use generative AI in the forward engineering, there’s a new incentive for us to actually create this description in textual form in a lot of detail.

    In the past, maybe we wouldn’t even do it at that level of detail. We would still, in the forward engineering, maybe have stories as the placeholder for a conversation because we want to build a new, fresh application. Now that we can use AI for the forward engineering, there is an incentive there to have very detailed descriptions. It maybe even changes the equation of cost benefit when we think about feature parity. That’s also one of the hypotheses. That with AI-accelerated reverse and forward engineering, feature parity might become less of a sticking point.
