  • It’s almost certainly something that will get worked out on its own. There isn’t enough volume to justify lithium battery recycling at this point. After a decade of EVs being mainstream, there will be.

    That said, GP is correct that EVs are about saving the car industry, not about saving the environment. Getting better walking/biking/public transportation infrastructure is the way to go. Ebikes, in particular, open up biking transportation to a lot of people who hesitated before. The amount of lithium used in them is tiny compared to cars, and the market can likely be served by sodium-ion batts, anyway.



  • The US is allergic to it, but needs to get over it.

    Aluminum wire was tried in the 1970s due to a spike in copper prices. The problem was that they just tried to swap it right in. Aluminum and copper have different rates of expansion. Over time, that would slowly loosen the connectors, and the wires would pop right out and cause a fire.

    You can design connectors to handle both, and you’ll see many electrical things today specify that they’re good for aluminum or copper wire. It still has a bad reputation among electricians; they haven’t unlearned the problem yet.

    Now, one place it’s more of a problem is in things like transformer windings. There are kilometers of wiring in any of them, so the higher resistance of aluminum is a problem.



  • There’s a thread of thought that pops up in pro-AI posters from time to time: technology can’t go backwards. The implication being that the current state of AI can only improve, and is here to stay.

    This is wrong. Companies are spending multitudes of piles of cash to make AI work, and they could easily take their ball and go home. Extending copyright over the training data would likely trigger that, by the industry’s own admission.

    No, self-hosted models are not going to change this. A bunch of people running around with their own little agents aren’t going to sustain a mass market phenomenon. You’re not going to have integration in Windows or VisualStudio or the top of Google search results. You’re not going to have people posting many pics on Facebook of Godzilla doing silly things.

    The tech can go backwards, and we’re likely to see it.
