But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
人类也不是生下来就是大聪明，从婴儿到成人，吃喝拉撒 20 年，还得加上学校教育、社会教育，这些都消耗食物、水、电等等能源。如果算「全生命周期成本」，AI 其实挺高效的，训练一次，就能无限次回答问题，而人类每次思考还得再烧脑子——大脑耗能约 20 瓦。

不仅仅是小鹏一家。由于L3在当前法律、安规等方面存在现实限制，多家车企也正在被掣肘。宣布今年3月上市的岚图泰山黑武士号称“中国首款量产 L3 级 SUV”；吉利、广汽也有新品，无一例外号称搭载“L3智驾”。然而——
