导读
这是 qntm 的科幻短篇《Lena》，以维基百科条目的口吻讲述一个人类大脑扫描/意识副本如何被反复复制、运行和消耗。标题借用了图像处理领域的标准测试图 Lena，暗示这个数字心灵也沦为技术基准与实验材料。
为什么经久不衰：它用冷静的百科笔法和一个熟悉的图像处理梗，把意识上传的伦理恐怖写得像既成事实，所以多年后仍让人不寒而栗。

实际会更快把脑仿真变成可调试、可操纵的工具，恐怖程度远超故事。
这故事有意思，但很不真实；我觉得不会那样发展，实际会恐怖得多。我们不会费劲去说服一个大脑图像合作，因为很快就没这个必要。对模拟大脑最先做的事之一就是调试：单步执行、测量参数、保存/重载状态、测试各种输入。合作会变得不必要，因为你总能从合作状态开始，或很快学会把大脑状态调成合作。然后真正诡异的部分才开始：我们会弄清大脑内部如何运作、如何制造最大愤怒和最大合作、如何植入虚假记忆、如何构造可信谎言、人类感知的漏洞在哪里；还可以模糊测试看能不能让大脑崩溃。我们已经在免费游戏成瘾设计上有了令人不安的进展，有了这种工具就能精确调参，最终知道该瞄准大脑的哪些部分。

It's interesting, but strikes me as very unrealistic. I don't think it'd go that way. In fact, it'd be far more horrifying. We wouldn't bother trying to convince an image of a brain into cooperation, because we simply lose any need to do that very quickly. One of the very first things we'd do with a simulated brain is to debug it. Execute it step by step, take lots of measures of all parameters, save/reload state, test every possible input and variation. And I'm sure it wouldn't take long to start getting some sort of interesting result, first superficial then deeper and deeper. Cooperation would quickly become unnecessary because you either start from a cooperative state every time, or you quickly figure out how to tweak the brain state into cooperation. And that's when the truly freaky stuff starts. Using such a tool we could figure out many things about a brain's inner workings. How do we truly respond to advertising? How to produce maximum anger and maximum cooperation? How to best implant false memories? How to craft a convincing lie? What are the bugs and flaws in human perception? We could fuzz it and see if we can crash a brain. We've already made some uncomfortable advancements, eg in how free to play games intentionally try to create addiction. With such a tool at our disposal we could fine tune strategies without having to guess. Eventually we'd just know which bits of the brain we want to target and just have to find ways of getting the right things to percolate down the neural network until those bits are affected in the ways we want. Within a decade we'd have a manual on how to craft the best propaganda, how to best create discord, or how to best destroy a human being by just talking to them.
脑扫描副本可批量复制做劳动，但伦理上令人不适。
我常想象拥有自己大脑扫描的可执行版本：在热情高涨能连续工作几小时的时候扫描自己，然后生成几千个副本一起做同一件事；几小时或几天后，在记忆/目标/价值观还没明显分叉前删掉副本，再生成新一批继续任务。要接受这方案，你得能接受自己可能作为上传副本被另一个自己派活，且接下来几小时的记忆会丢失。删除只分叉了几小时的副本，更像喝酒断片而不是死亡。这样能获得几千个共享同一创作愿景的人的巨大产出。但我绝对不愿自己的大脑扫描被自由复制、供任何人下载和滥用。

I've often imagined what it would be like to have an executable brain scan of myself. Imagine scanning yourself right as you're feeling enthusiastic enough to work on any task for a few hours, and then spawning thousands of copies of yourself to all work on something together at once. And then after a few hours or maybe days, before any of yourselves meaningfully diverge in memories/goals/values, you delete the copies and then spawn another thousand fresh copies to resume their tasks. Obviously for this to work, you would have to be comfortable with the possibility of finding yourself as an upload and given a task by another version of yourself, and knowing that the next few hours of your memory would be lost. Erasing a copy that only diverged from the scan for a few hours would have more in common with blacking out from drinking and losing some memory than dying. The creative output you could accomplish from doing this would be huge. You would be able to get the output of thousands of people all sharing the exact same creative vision. I definitely wouldn't be comfortable with the idea of my brain scan being freely copied around for anyone to download and (ab)use as they wished though.
标题来自图像处理标准测试图 Lena，解释了这个隐喻。
一篇写得很好的故事，激起一种蔓延的、压抑的恐惧。对像我这样困惑标题与故事关系的人：标题“Lena”指瑞典模特 Lena Forsén，她出现在标准测试图像“Lena/Lenna”中。

A well-written story that inspires a sort of creeping, muted horror. For anyone like me who is confused by the relation of the title to the story, "The title "Lena" refers to Swedish model Lena Forsén, who is pictured in the standard test image known as "Lena" or "Lenna" <https://en.wikipedia.org/wiki/Lenna>."
百科体中立语气放大恐怖，并关联 Robin Hanson《The Age of Em》。
非常好，我喜欢这种维基百科格式。这是个很棒的手法，让作者能用我们熟悉的格式指向相关主题。维基百科条目的中立语气预期让故事更冷：实验者的一切行为都被冷静描述，像是在描述对一只甲虫的实验。Robin Hanson 写过一本（名义上非虚构的）书，讲这种复制心智的经济。

Really good, and I love the wikipedia format for this. It's a great trope allowing the author to gesture at related topics in a format we're all familiar with. I think the expectation of a neutral tone from a wikipedia article makes it even more chilling. All of the actions of the experimenters are described dispassionately, as if describing experiments on a beetle. Robin Hanson wrote a (nominally non-fiction) book about economies of copied minds like this[1] [1]https://en.m.wikipedia.org/wiki/The_Age_of_Em
