Related story, while applying a firmware update to my Kawai CA49 piano, I bricked it due to flashing the wrong file (The process was broken, and I got desperate and tried something stupid, which bricked the piano). Claude walked me through looking for signs of life, and since OTA from the phone app wasn't working for me, it downloaded the Kawai Android APK, decompiled the Java, figured out the hardcoded key used for encrypting the firmware update. Extracted the piano firmware update, decrypted it, and then wrote a flashing script to program the piano from my laptop via bluetooth. My piano was back to working within an hour.

  I'm not convinced that's where we are heading. LLMs are really good at explaining things ("explain to me like I'm a 5 year old").

      Some manager at LLM provider: "hey, we can sell 'education' ability as a separate product!".
      - baq 4mo ago
        You jest, but I’m actually convinced education-tuned LLMs are (today) the only way education outcomes can actually improve in the AI era. As is, students are leveraging them for doing homework which makes homework useless, you want and economically need a model which can work as a 1:1 tutor with minimal supervision (and some hardware so lessons aren’t keyboard-driven).
        zx8080 4mo ago
        > and some hardware so lessons aren’t keyboard-driven). What's wrong with (screen-, probably) keyboard?
        baq 4mo ago
        Writing with a pen or pencil has better learning outcomes than with a keyboard for neurological reasons. https://pmc.ncbi.nlm.nih.gov/articles/PMC11943480/ https://pmc.ncbi.nlm.nih.gov/articles/PMC11943480/
        NonHyloMorph 4mo ago
        Most kids can't use a keyboard and never will. Their Apple Pencil scribbles don't seem to make them particularly smarter. Pen&pencil-> create something from (almost) nothing. Stylus input-> subpar slow interface for computation. Ipad data storage above par organisational help (no loosing lousy stuffed in bag paper). I kinda liked the AI to transpose handwritten/drawn notes into digitally orderable artifacts. Seen a couple Show HNs. Are there any advances in the field (preferably OSS or one time purchaseable as alternatively) (To add on to this: the utter physical imprecision of stylis pens is annoying. I can FEEL where a sharpt tip of a tool that is elongating my hand touches a surface and how it moves on a very fine scale/resolution. Probably not a problem for people who have not developed highly sensitive sensomotor perception because they grew up with a lot of flattness in there surrounding and not much plasticity, but: my god are these things clumsy. I always want to reach for a sharpener when i use an apple pencil lol.

    It's enough to make "explanation" a separate "educational" license to make it less broad used. Or disable it in some countries (this is happening already).
    - fivestones 4mo ago
      Wait, really? Can you give specifics?

        Use VPN and try switching countries for yourself. Start from non-EU ones. You'll see.
    - Flere-Imsaho 4mo ago
      This is why locally running LLMs must be the future. We don't all need PHD level AIs to answer 99% of our queries, or to teach us a new thing. I'd encourage everyone to learn how to run and deploy local LLMs, even if they are not quite there yet in terms of performance.

    There's a big difference between having something explained to you and developing expertise in it. I don't see an AI-as-explainer future where expertise isn't sacrificed en masse. Capitalism rarely supports a currently economically unproductive alternative for future good reasons. The recent AI tech layoffs are a warning sign that corporate leaders will happily shoot their company's (and the future's) expertise to pad next quarter's financials and trust in 90% correct, but much cheaper, AI.
    - Beijinger 4mo ago
      "There's a big difference between having something explained to you and developing expertise in it." No, there isn't. You get things explained in University. Then you build on top of this knowledge.
      - ethbr1 4mo ago
        That's not at all how university works. You are explained things (least important part) and then you invest substantial amounts of time in practicing and exercising those new skills. Then, in your junior level jobs, the same cycle repeats. That exercise component isn't going to happen in university with AI in the loop, because AI will be able to shortcut basic practice. And it isn't going to happen in junior level work, because AI will be able to do those jobs more economically efficiently.

        Has there ever been a modern time when this wasn't the case? I mean: I can only go back so far, but I remember the 1980s well-enough. At that time, most of the new information that came into my brain from outside was sourced from public schools, newspapers, and the evening news on TV. None of these sources were particularly unfiltered, uncensored, or unbiased. It was always an abbreviated approximation of someone else's idea of the truth.

    Eh. The only real things you need are: - On startup processing begins at a known address, and you put the bootloader code over there. Hardware engineers can guarantee this for you. - Every time you execute an assembly instruction, the program counter either explicitly jumps to a new location or else it just increments by 1. Hardware people can also make this happen as easily as implementing an adder. Don't get me wrong, there are LOTS of layers between the hardware and most "useful" programs any of us will ever write. But all of them are pretty understandable. They're often not very complicated, just tedious.
    - tonyarkles 4mo ago
      Similarly for making a basic CPU that implements the logic you’re describing. In 2006 or so I made a super simple microcontroller on an FPGA for a course project. It had a whopping 256 bytes of RAM, 1kB of ROM, and I think four 8-bit registers plus a 16-bit program counter. You could only jump +/- 256 bytes. It was largely useless but also incredibly satisfying.
- pmcarlton 4mo ago
  I think it will be just like Dr. Know in Spielberg's "AI" movie from 2001 — I found it amazing how the oracle, though giving mystic-sounding obfuscated answers, was actually intelligent enough to figure out (a) what the kid was asking for and (2) give the correct answer.
  - jlaternman 4mo ago
