Singapore's Biological Data Center Explained
好吧。 新加坡刚刚启动了一座数据中心，
其运行依靠
活体人类脑细胞。 在你问他们把谁的脑细胞
放进电脑之前， 事情其实变得更离奇了。
他们并不是从某个人的 大脑中提取的。
这一切都可以从活人的血液开始， 这意味着
理论上， 他们可以把你也放进数据中心。
我是 GigaChan， 我来告诉你这是如何运作的，
因为新加坡现在拥有
20台生物计算机， 它们使用真实的人类神经元作为
计算系统的一部分。 先说清楚，
当我说“依靠它驱动”时， 并不是指神经元会产生
电力。
这些神经元实际上是在处理信息。
那么他们是从哪里弄来的？据报道， 这些神经元来自
被重编程为干细胞的血细胞。 制造它的 Cortical Labs 公司
这些计算机， 已经展示了这能变得多么
个人化。
该公司的首席执行官表示，他已经提 供了 大约十毫升自己的血液，以便
让神经元能够—— 你可能已经猜到了— —去玩《毁灭战士》。
没错，就是那款老电子游戏。 你真可以说那位创始人为工作
倾注了血汗与泪水。 让我来告诉你这一切是如何运作的。
科学家可以从血液中提取细胞， 并将它们重新编程为所谓的
诱导性多能干细胞。
这基本上意味着将成体细胞 重置为一种状态，使其能够
再次分化成多种不同的细胞。 然后他们利用化学信号引导
那些
重置后的细胞变成真正的人类 神经元。
不， 那些神经元并不包含供体的
记忆或个性，但它们
确实包含来自供体的 遗传信息。
现在取出至少20万个这类神经元 直接将它们培养在
覆盖着微电极的 硅芯片上。
神经元生长并相互连接 形成一个活体神经
网络。 这就是它化身为计算机的时刻。
电极将特定模式的电信号 发送到神经元中。
神经元通过放电做出反应 电极则记录下这种反应。
没错 软件会将其重新转化为数字
信息。
因此信息以电信号形式输入 活体人类神经元
对其进行处理 随后信息再输出出来。
而且由于这些是活细胞 计算机实际上必须喂养
它们并维持其生命。几十年来 人工智能一直
试图让硅芯片模拟生物 人类神经元。
这一次 我们可能直接跳过了模仿阶段。
如果你想了解更多，可以去查查CL1。

Original transcript (English)
All right. Singapore just launched a data center powered by living human brain cells. And before you ask whose brain cells they're putting in the computer, the situation gets weirder. They don't take them from somebody's brain.
This all can get started with blood from a living person, meaning theoretically, they could put you in the data center. I'm GigaChan, and I'm gonna show you how this works because Singapore now has 20 biological computers that use real human neurons as
part of the computing system. Let's be clear. When I said powered by, I didn't mean the neurons generate electricity. The neurons actually process information. So where do they get them? Reportedly, the neurons are from blood cells that were
reprogrammed into stem cells. And Cortical Labs, the company that makes these computers, has already shown how personal that can get. The company's CEO says he already gave about 10 milliliters of his blood so that the neurons could, you might have guessed it, play with Doom.
Yep, that same old video game. You could really say that founder put his blood, sweat, and tears into his work. Let me tell you how all this works. Scientists can take cells from blood and reprogram them into what is called induced pluripotent stem cells. That basically means resetting an adult cell to a state where it can become
multiple different cells again. Then they use chemical signals to guide those reset cells into becoming actual human neurons. And no, those neurons don't contain the donor's memories or personality, but they
do contain genetic information from the donor. Now take at least 200,000 of those neurons and grow them directly across a silicon chip covered in microscopic electrodes. The neurons grow, connect with each other, and form a living neural network. And this is where it becomes a computer.
The electrodes send patterns of electrical signals into the neurons. The neurons respond by firing, and the electrodes record that response. And yeah, software translates it back into digital information. So information goes in as electricity, living human neurons
process it, and then information comes back out. And since these are living cells, the computer has to actually feed them and keep them alive. For decades, AI has tried to make silicon imitate biological human neurons. This time, we might be skipping the imitation.
And if you want to know more, look up CL1.
