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.

如人形机器人的手指空间极其有限，却需要容纳驱动、传动、感知等多重功能。传统减材制造在面对如此微小的复杂部件时，往往面临“刀具下不去、结构做不出”的困境。高精度金属打印突破了这一物理限制，能在极小空间内集成复杂的内部传感结构与��性体梁，将复杂的内部油路、电路通道与弹性体结构一体化成型，使显微级的力觉感知成为可能。。搜狗输入法下载对此有专业解读
There is reason to be optimistic though.
