抬头张望四周,春风拂过的世界好像全部都在缓缓地松动起来。院里几棵刻满了岁月皴裂的老槐树,尽管依旧沉默地站立着,像几个岁月老人在铅灰的天幕下打着盹,但铁灰色的枝干末梢,在微风的轻轻摇曳中已染上了一层淡淡的青晕。整个冬天涂着暗灰色彩的马尾松,也明显变出油润的深绿。路旁并排矗立的白杨,光秃秃的枝干举着稀疏的鸟巢,灰白的树皮上布满块状的斑纹,但枝条的顶端却鼓起了小小的、毛茸茸的苞。苞蕾的颜色与树皮几乎无别,它们紧紧的,像抿住的嘴唇,但不再是向下的、蜷缩的、听天由命的姿态,而是随着翘起的枝干朝向天空昂着头,表现出不可逆转的生命活力。尽管斜逸枝丫上的芽苞伸手可及,你却不忍心去触碰,害怕惊动了一场正在发生的生命转机。

“自动驾驶行业将跳过L3,直接从L2迈向L4级全自动驾驶”,何小鹏认为,L3的本质是“过渡性技术陷阱”,为规避风险而堆砌的大量规则,使其沦为“看似安全却限制进化”的存在。与其如此,不如集中攻克L4难题,以真正的技术创新来解决技术发展中的问题。

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.
