  • IANAL nor intelligent, but after skimming the text of the directive I felt like the definition of damage is very limited. In particular, if I understand correctly:

    our business to lose this giant contract

    would not be covered by this directive, this directive is only about a human being hurt in some way,

    thousands of consumers left with bricked devices

    would be covered in case of “your game installs a kernel-level anticheat and the anticheat breaks PCs”, but not in the case of “you uploaded an upgrade to a firmware of the washing machine you produced and it bricked the machines”; the directive is not about a product breaking, but about the product breaking your health, other property or data,

    my washing machine to eat my dog

    is basically the exact case this directive covers.


  • Hasn’t Google already made advances through its Alpha Geometry AI?? Admittedly, that’s a geometry setting which may be easier to code than other parts of Math and there isn’t yet a clear indication AI will ever be able to reach a certain level of creativity that the human mind has, but at the same time it might get there by sheer volume of attempts.

    Wanted to focus a bit on this. The thing with AlphaGeometry and AlphaProof is that they really treat doing math as a game, not unlike chess. For example, AlphaGeometry has a basic set of rules, it can apply them and it knows when it is done. And when it is done, you can be 100% sure that the solution is correct, because the rules of the game are known; the 28/42 score reported in the article is really four perfect scores and three zeros. Those systems do use LLMs, but they really are only there to suggest to the system what to try doing next. There is a very enlightening picture in the AlphaGeometry paper here: https://www.nature.com/articles/s41586-023-06747-5#Fig1

    You can automatically verify correctness of code the same way. For example Lean, the language AlphaProof uses internally, can be used for general programming. In general, we call similar programming techniques formal methods. But most people don’t do this, since this is more time-consuming than normal programming, and in many cases we don’t even know how to define the goal of our code (how to define correct rendering in a game?). So this is only really done when the correctness of the program is critical, like famously they verified the code of the automatic metro in Paris this way. And so most people don’t try to make programming AI work this way.



  • In Poland:

    • driver's permits are not a thing. In general, it's illegal to drive without a professional instructor (with parents, for example) before getting a driving license, though a lot of people, especially in the countryside, will still do so,
    • you can only drive after turning 18. You can start the course a few months earlier, but you can only take the final exam after you turn 18 (there exists a category that allows you to drive after turning 16, but it's limited and IME extremely unpopular),
    • you need to go to a paid course, which includes theory classes and at least 30 hours of driving with the instructor,
    • most people drive in a car owned by the instructor or the driving school, as the car must have another pair of brakes for the instructor,
    • you need to pass a theoretical and a practical exam in one of the centers (Wojewódzki ośrodek ruchu drogowego),
    • the theoretical exam is just closed questions. You need to get 68 out of 74 points, but (AFAIK, this has changed over time) all the questions are known, so people will just cram them,
    • the practical exam is first some maneuvers on the center grounds, and then a ride around the city. The exam is rather objective and is failed if you do any big mistake or fail any exercise twice,
    • the exams are not easy. The data I found is for each WORD, but in general I feel like the pass rate is around 50% for the practical exam and 70% for theory. It's not incommon for somebody to only pass their practical exam on like 5th attempt,
    • there were supposed to be some restrictions for new drivers, but they had been discussed for a long time, even back when I passed my license before the pandemic, and I have no idea if they ever actually came into force,
    • some people think that the system is super flawed. Here's some discussion by the Supreme Audit Office in Polish: https://www.nik.gov.pl/aktualnosci/system-szkolenia-kandydatow-na-kierowcow.html,
    • costwise, it's apparently like 4000 zł for the course right now. Exams are paid per attempt, 50 zł for the theory and 200 zł for practice. 1 euro is 4.33 zł as of writing, but you need to take into account the difference in purchasing power and it's probably not much cheaper than Germany even if you pass both exams the first time.


  • I’m super conflicted about this article. The portion on disabilities is great! But then, we see this:

    It’s considered an ‘AI-complete’ problem, something that would require computers that are as fully complex as, and functionally equivalent to, human beings. (Which about five minutes ago was precisely what the term ‘artificial intelligence’ meant, but since tech companies managed to dumb down and rebrand ‘AI’ to mean “anything utilizing a machine-learning algorithm”, the resulting terminology vacuum necessitated a new coinage, so now we have to call machine cognition of human-level complexity ‘AGI’, for ‘artificial general intelligence’.)

    This is honestly the first part that’s outright objectively wrong. A quick look at the Wiki will tell us that the term AGI was already used in 1997, for example. You can’t say that it was made up by tech companies about five minutes ago. And the author returns to this “rebranding” later in the article, so you can’t just brush this away as a misguided aside; it’s just clear that the author does not really know anything about AI, yet is willing to write an article about it. Mix this with the snarky tone, and it just gets very sad.

    It’s not like that I don’t agree with what they say about AI either, and I definitely agree with the big conclusions; it’s not like there are no people with a similar opinion that know more about AI (Gary Marcus, for instance), the comparision to disabilities is the novel (to me) part. But I just couldn’t share this article with anyone. As I am writing, the top comment on [email protected] is criticizing the same part of the article, except in less nice words. I don’t think that the person who wrote that comment will learn anything helpful about disabilities from this article…



  • Imagine a soccer ball. The most traditional design consists of white hexagons and black pentagons. If you count them, you will find that there are 12 pentagons and 20 hexagons.

    Now imagine you tried to cover the entire Earth in the same way, using similar size hexagons and pentagons (hopefully the rules are intuitive). How many pentagons would be there? Intuitively, you would think that the number of both shapes would be similar, just like on the soccer ball. So, there would be a lot of hexagons and a lot of pentagons. But actually, along with many hexagons, you would still have exactly 12 pentagons, not one less, not one more. This comes from the Euler’s formula, and there is a nice sketch of the proof here: .
