  • Depends on how far you’re thinking.

    Nowhere else in the solar system is anywhere near as habitable as Earth, and there’s still lots of empty space to fill on Earth. Consider for a moment how much easier a self-supporting city on Antarctica would be than a city on Mars. Human space travel is done purely for science or recreation, at this point, not for growth.

    If you want to “disperse” in any significant way, you have to start looking at exoplanets, and it’s going to take centuries to get there, and we don’t have the technology to survive that yet. Once we do, there’s a strong argument for it, because our planet and solar system will only last so long.







  • the aforementioned potato cabal (it really exists. Theres a fun Half-as-interesting video on how it affects the price of fries)

    Farmers do love a good cabal. Here in Canada there’s literally a state agency that does all the buying and selling of dairy products. Drives the Americans crazy.

    Insane chip profit margins, because of the consumers’ willingness to pay. Consider a meal containing meat. Sure the manufacturer is making a profit, but can you imagine how much more profit they would be making by selling you a meal with the same amount of calories, but made of potatoes or corn? The consumer is willing to pay, say, $10 for a simple meal containing some meat, but what about half a meal? Maybe $3-5? Well, here come potato chips. They act like they’re half a meal, but they’re actually just cheap oil and a spud. The consumer will still pay more for it, so the companies can charge that much and make a huge profit from the willingness to pay of their dupes.

    I mean, you can go and look at how much money they (Utz for example) end up making. It’s not different from the next publicly traded corporation, so there’s got to be expenses somewhere in there.


  • One thing that would have been really tough would be high-temperature pressure vessels, like for heat engines. Other materials with good tensile strength exist (as do wood skyscrapers!), and so do refractory materials, but if you need both at the same time you’re looking at either high-tech ceramic composites or metal.

    Does silicon even form metallic bonds?

    Uhh, not sure. The band structure of the crystal lattice supports conduction like a metal, but not without an impurity to introduce the initial carrier, which is the whole thing behind why it’s useful for electronics.

    IIRC bond type is kind of a continuum.
