我对自动驾驶的兴奋程度几乎有点“不合理”。它将成为几十年来首个能明显重塑户外物理空间与生活方式的技术。更少的停放车辆。更少的停车场。对车内外的行人来说将更安全。更少的噪音污染。更多空间被重新归还给人类。人类的注意力与脑力不再浪费在“保持车道”这种任务上，可以投入到更有意义的事情中。实物与商品的配送将更便宜、更快速、可编程。这一切不会一夜之间发生，但会出现一个清晰的分界：自动驾驶出现之前的时代，和自动驾驶普及之后的时代。 I am unreasonably excited about self-driving. It will be the first technology in many decades to visibly terraform outdoor physical spaces and way of life. Less parked cars. Less parking lots. Much greater safety for people in and out of cars. Less noise pollution. More space reclaimed for humans. Human brain cycles and attention capital freed up from “lane following” to other pursuits. Cheaper, faster, programmable delivery of physical items and goods. It won’t happen overnight but there will be the era before and the era after.
