  • 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.
















  • This is a good analysis, but it’s slightly different from OP’s statement.

    Median real wages actually are up since 1979. It became something of a meme post-2008 to say that median wages have been flat since that time. That was true for a few years following the Great Recession, but they caught up and went quite a bit higher. It’s possible the numbers will cycle around to that again, but it’s not where we’re at right now.

    What the graphs in the article are arguing is that wages over that time are much lower than they should be given productivity increases.

    Let’s say you work for one hour making a widget, and you get $1 for that time. Your boss sells the widget for $5 and pockets the difference. Now there’s an increase in productivity, and you can make two widgets in the same hour. You still get paid $1 for that hour, but your boss is selling those two widgets for $10 total now. You’re not getting a raise just because of that productivity increase.

    You might get a raise due to inflation. With 4% inflation, you get to make $1.04/hour, but your boss is now selling those widgets for $5.20 each. This is more or less the story since 1979.

    That difference between productivity and real wages is what’s charted out above. It tells you exactly who the real moochers are in society.

    This all tracks very neatly with a decline in union membership.
