  • Safety issues aside, I don’t like the power grid topology they create—where power is distributed radially from a single centralized source. Systems like that are fragile and inflexible, with a single point of failure; and they promote similar institutions to control them.

    Networks are more robust when they’re distributed and redundant, with lots of interconnected local sources. Solar and wind are a lot more amenable to that kind of structure.

  • There’s not a hard-coded wiring diagram of how the neurons from the brain connect to the rest of the body—everybody’s wired a bit differently, and the brain normally figures out how to work with what it’s got during development. So there’s no one-to-one way to connect the nerves from one person’s brain to those in another person’s body—and if it doesn’t get the signals it’s expecting, it will just seem like noise.

    Besides which—if I remember correctly, you can’t generally reconnect severed nerves. Instead, the remaining portion of the nerve cell has to grow a new axon that retraces the route of the old one, and it can only trace the old path for a limited distance (like, if it’s close enough to receive chemical signals from the original site). But I’m not sure I’ve got all the details right on that.

  • The team matched the products with each other based on a variety of factors such as the ingredients, packaging, and size, to achieve the closest match possible. So, for instance, almond milk was paired with normal milk, vegan brownies with dairy-based brownies, and plant-based meat with regular meat. Other products included were lasagne, coleslaw, pesto, mayonnaise, yoghurt and cake.

    So they only looked at products traditionally made using animal products, and compared them to similar products with plant-based substitutes.

    An alternative headline could have been “Imitative foods contain more imitative ingredients”.

  • In each and every region the researchers looked at, Deo said, “there was distinguishable information about movements that span the entire body, not just the canonical body part the motor homunculus model would have suggested.” In other words, while one region might be most strongly activated for hand movements, it also contains signals concerning movements in the face, legs, and everywhere else.

    Seems like that could go a long way towards explaining synesthesia as well.

  • Pre-2006:

    • End of the Cold War and the USSR
    • 9/11, the war on terror, invasions of Iraq and Afghanistan
    • Cell phones, laptops, public GPS, WiFI
    • The internet, Wikipedia, Amazon, Facebook, YouTube, Reddit
    • Public awareness of global warming

    Post-2006:

    • 2008 financial crisis
    • Smart phones
    • TikTok, Instagram, Netflix
    • Covid-19
    • LLMs, generative AI

    I’m sure I’m overlooking some things, but the pre-2006 decades seem like a more drastic change overall.
