  • The problems listed in the article are real. we’ve built a system:

    1. Where a lot of economic growth stems from an increasing supply of (cheap) labour
    2. That relies on people of working age being able to financially support a retiree class.

    Both of these are going to fall apart if the population stops growing. The smaller group of working age people won’t be enough to support the amount of retirees, and without population growth there’s no economic growth.

    It’s sad that economists correctly see all this coming but then conclude that the only solution is “make more babies.” It’s short term thinking almost by definition, because in the limit it’s rather obvious that at some point we will not have the resources to support any more people. And the closer we get to that limit the less each individual person will have (even worse when wealth is not equally distributed).

    Unfortunately I don’t see any economist putting forth a plan that accepts population decline and alters the system to account for it. It wouldn’t be easy but it seems no one is even trying.


  • VW is good at making cars, but bad at software. They’ve had to delay the introduction of new models (Golf, ID.3) because of software issues. Rivian has sort of the opposite problem: their production lines sit still often because of problems in the supply chain.

    Volkswagen has the expertise to solve Rivian’s production and supplier problems, and the cash they will need to survive and develop some cheaper models (the EV market is stagnating right now for a lack of budget options, and Rivian only sells trucks and SUVs). And they’re hoping Rivian software engineers can help them fix their software woes.


  • Pretty much the perfect form factor in my opinion. Put the back seat down when you need to transport cargo, up for people. Really practical. If you want to do camping trips or road trips where you need to move four people with cargo, you can get one with a towing hook.

    The one thing it’s not great at in my experience is transporting babies around. There’s just not quite enough space for the car seat, stroller, two parents and assorted diapers and stuff. We can make it work, but it’s quite uncomfortable.



  • There is a saying in business: Under-Promise, Over-Perform, or Over-Deliver.

    SpaceX does the opposite of this.

    It literally doesn’t matter though: everyone and their mother are buying falcon 9 or heavy launches. SpaceX accounts for almost 90% of the world’s launched upmass. They are simply the cheapest most reliable option out there and it is not close. The only reason not to fly on a SpaceX rocket is national security or wanting to keep your own domestic launch industry alive.

    It seems to me that, since the set of real numbers has a total ordering, I could fairly trivially construct some choice function like “the element closest to 0” that will work no matter how many elements you remove, without needing any fancy axioms.

    I don’t know what to do if the set is unordered though.





  • Honestly, I think it may be possible to build entire roads with enough crushed metal elements in the asphalt/concrete and a slight low power charge throughout the entire surface would be able to keep any vehicle battery at a steady charge.

    You might be underestimating how much power a car consumes while driving. For example, a Tesla model 3 has an efficiency of about 130 Wh/km in mild weather at highway speeds. Assuming that on the highway you’ll travel 100 km/h, that means you’ll use 130*100 = 13.000 Wh/h, a constant power draw of 13kW. That’s enough to power perhaps 8-12 houses on average.

    A km of road could have, let’s say, 200 cars on it (4 lanes, 20m per car). That means you’d need to pump about 2.6 megawatts of power into every kilometer of road to keep them all topped up.

    EDIT: fucked up math


  • Semmelweis discovered that a particular type of infection was much less likely to occur when doctors washed their hands with chlorinated lime water between doing an autopsy and examining a patient. However he did not know why or how this worked, and did not discover microorganisms (which were already observed by Antoni Van Leeuwenhoek some ~180 years earlier).

    Another European here. Might be because I’m into baking but I don’t think a bagel should be classified as a roll. Bagels are boiled in water prior to baking which gives them a rather unique texture compared to rolls.

    Sadly most commercially available “bagels” are not actually produced in this way.
