消失的天空

几个月前,一名美国宇航员碰巧把一把工具掉进了轨道,从而引发了人们对于这样一个猛冲猛撞的物体可能破坏一颗昂贵的卫星、甚至威胁上面的生命的危险性的担忧。过了不久,中国炸毁了它的一颗卫星,从而立即倍增了因为难以搜寻而显得十分危险的围绕轨道旋转的废弃物的数量。

世界再次认识到了存在于我们天空的奇怪状况。天空是一个特殊并且没有得到恰当管制的领地。随着全球污染和技术的出现,改变这一状况变成了一个越来越紧迫的问题。

在大多数情况下,天空的规则与那些管制世界上海洋的规则相似。除开那些近陆地的海洋——那是受到与该国陆地边界同样方法管制的,其他的海洋是属于人类共有的。其结果是,天空通常在人们心目中通常只是一种交通的概念。航线和战斗机是在与地面相近的“管制”空域运作的,至于国境,则被认为你飞得越高,那么其概念就越薄弱。在此方面执行的脆弱的条约大多是因为很少有国家能在如果高的领域主张其权利。

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
