  • It’s a myth that the GDPR is a useful tool in such cases. You know the expression “protected by copyright”? That’s how lawyers protect data.

    The GDPR grants people rights over data concerning them, similar to how copyright grants rights over data. That means 2 things.

    1. It’s rarely obvious that some data processing is illegal. It’s not obvious if it happens without consent. But even so, you often don’t need explicit consent to use someone’s data. EG when we write about French president Macron, then that is Macron’s data under the GDPR. Of course, you don’t need his consent to discuss or report on politics, and so you usually don’t need his consent to discuss his person.

    2. Enforcement is difficult and expensive. Think about the problems the copyright industry has. Surveillance tools like Content ID can at least rely on knowing what exactly they are looking for. Besides, much of the world has similar laws supported by influential industries. Little chance to do that for GDPR.

    Basically, using GDPR to protect actual secrets is like using copyright for the purpose.










  • People want goods and services, as well as jobs. Politicians need to make that happen, and so they listen to the people who know how to make that happen. Sometimes that goes wrong because eventually employers don’t have quite the same goals as their employees. There is no good alternative, though.

    One player that clearly had a lot of input is the (news) media. EG the press publishers want to license their old news articles for AI training. They can do that thanks to EU copyright law. That’s free money. But news articles talk about living people, which means they contain personal data.

    Despite competition from social media, the trad media, including press publishers, is still extremely influential. Politicians need their favor to get votes.

    I don’t see how Big Tech is getting much here. Of course, NGOs need the media’s favor just as much as politicians. Pointing the finger at some nebulous forces from outside is certainly the safest choice, politically speaking.


  • Plutonium-238’s half-life is 87.7 years, Americium-241 is 432.6 years. Which… is almost 5 times longer, so… not sure why that’s cringe?

    What’s cringe is the word “staggering”. Natural radioactive isotopes have half-lives on the order of billions of years. All elements heavier than iron are created in supernovae. Billions of years have passed since the novae that created that heavy elements now on earth. Anything with shorter half-lives is no longer around. (More correctly, one should talk decay chains.)

    What’s staggering is that these isotopes are available at all. They are artificially created in nuclear reactors. Mass production of Pl-238 began only during WW2 for bombs. That’s almost a half-life ago. The shorter half-life makes the availability of Pl-238 much more impressive.

    I believe they’re referring to the fact that it’s not an element of major topic. This is the first time I’ve ever heard of it.

    There are over 100 named elements. I don’t think I could name half of them. Americium is relatively prominent because of it’s use in smoke detectors. And while I’m at it: Americium is the element. Americium-241 is a specific isotope; a specific variant, chemically identical to other variants but with slightly different physical properties.

    There are a number of isotopes suitable for RTGs. It’s a matter of trade-offs. There’s half-life, which is basically how fast the properties of the material change. There’s also energy density and how bad the radiation is for the device. And always, there’s cost. Fun fact, in Chernobyl they did try robots, but the electronics could not withstand the radiation. People don’t withstand it either, but there’s a lot of them.
