機器裡：做在硬體那一層

adjective · C1
In computing, a part of a system that is hard-wired is built into the machine's physical parts, so it works the way those parts make it work and an ordinary user cannot change it with software.
硬體寫死的
核心畫面
Think of one wire soldered inside a machine. Above it sit the instructions, the software, and those can be rewritten in a second by anyone with the right screen. The wire cannot. To move it you have to open the case, cut it and lay it again. Anything hard-wired lives on the wire layer, so arguing with it, updating it or deciding otherwise does no good at all. English then lifts that layer picture onto a person: a reaction that sits in the wiring and not in the instructions.
可以想成機器裡焊死的一條線。線的上面是程式，也就是指令那一層。程式想改，幾秒鐘就改好了。線不行，要改得把機器拆開、剪…更多收起
可以想成機器裡焊死的一條線。線的上面是程式，也就是指令那一層。程式想改，幾秒鐘就改好了。線不行，要改得把機器拆開、剪掉、重接。所以 hard-wired 說的是「在更底下那一層，動不了」。後來英文把這個分層的畫面整個蓋到人身上。有些反應就像那條線，不是靠下決心就能改掉的。Two branches
人身上：天生帶著、改不掉
把人腦當成機器，把個性放到「線」那一層來看。這是比喻上的連結，不是對大腦的科學主張。

天生如此、改不掉的
