命运号角

There are programs advertised to “securely erase” hard drives using many overwrites of 0s, 1s, and random data. But if you want to keep the secret on your hard drive secure against all possible future technologies that might ever be developed, then cover it with thermite and set it on fire. It’s the only way to be sure.
有一些程序用0、1和随机数“安全删除”硬盘数据。但是你也不想让未来科学解码你硬盘上的秘密，那唯一的办法是涂上铝热剂，放在火上。

He applies the same logic to the human brain to suggest that cryonics patients should one day be revivable:
他认为这方法适用于人类大脑，冷冻会员应该是可复活的：

Pumping someone full of cryoprotectant and gradually lowering their temperature until they can be stored in liquid nitrogen is not a secure way to erase a person.
把人灌上冷冻保护液，慢慢降低温度直到储存在液氮中，不是一个安全的方法去删除一个人（保持大脑原子结构）。

In other words, it’s reasonable to assume that the fanciest future neuroscientists will become so good at reading a damaged vitrified brain for clues as to its original structure that a typical combo of aging, disease, heart stoppage, and vitrification likely won’t be able to “stump” them. And to cryonicists, if future scientists can examine your vitrified brain and figure out what it’s supposed to look like, you’re not dead—by definition.
换句话说，我们有理由假设未来神经系统专家擅长解读一个受损的玻璃化大脑，以原结构的衰老、疾病、心脏停跳、玻璃化的结合为线索，所以玻璃化可能不会为难他们。而对冷冻专家来说，如果未来科学家能检查你的玻璃化大脑并算出原结构，按定义讲，你不是信息死亡的。
