关于 AI,人们还低估了一件事,这也是我回答的第二部分:一个迷思。我在书里归纳了三个关于 AI 的迷思。
One thing about AI that people underestimate, and this is the second part of my answer, is a myth. There are three myths about AI that I identified in my book.
第一个迷思:AI 代表了全人类。跟它聊天时,无论你在尼日利亚、法国还是美国,你都会觉得:嗯,它懂在拉各斯、在巴黎、在洛杉矶生活是什么滋味。
The first myth is that AI is representative of humanity. When you talk to it, whether you're in Nigeria, France, or the USA, you feel like: yeah, it understands what it feels like to live in Lagos, or Paris, or Los Angeles.
你这样想。最早的 AI,是在 Twitter 这类论坛上训练出来的。
Think about it this way. AI was initially trained on forums like Twitter, back in the day.
后来发生了什么?尤其是微软用 Twitter 训练自己的 AI 那一次:那正值特朗普第一次竞选总统,他说了些针对墨西哥人的十分难听的话,说他们都是强奸犯,正涌进美国,等等。
Then what happened, especially with Microsoft training its own AI on Twitter: it was during Donald Trump's first presidential election, and at that time Trump said something pretty nasty about Mexicans, that they're all rapists, that they're coming, et cetera.
当时的 Twitter 上,很多人都在这样议论墨西哥人。AI 学了去,开始大量复述那些对墨西哥人的污蔑。微软只好把它彻底下线。
You'd go on Twitter, and a lot of people were talking about Mexicans that way. The AI learned from that, and started regurgitating a lot of bad things about Mexicans. Microsoft had to unplug it completely.
于是我们说:好吧,这条路走不通。我们决定从 Twitter 换到 Google Scholar:综述、研究,经过同行检验的东西。
So we said: okay, that doesn't work. We decided to switch from Twitter to Google Scholar: reviews, studies, things that have been verified by our peers.
效果好多了。AI 不再频频出错,表达更有分寸,推理也更好了些,这才有了我们今天的大语言模型。
And that was way, way better. Now AI doesn't make as many mistakes, it's a little more nuanced, it reasons a little better, and we have the LLMs that we have today.
这是好消息。但你再往深挖一层,问一句:好,这些研究、报告、电影,都是谁写的?
That's great news. But now you dig a little deeper and ask: okay, who writes all these studies, these reports, all these movies?
答案是:在西方世界,80% 的出版物出自 8% 到 12% 的人之手。是那些有时间、有特权、有钱去写作的人。
Well, in the Western world, 80 percent of publications are written by 8 to 12 percent of the people. Those who have the time, the privilege, and the money to write.
今天,我可以写书。我的父母写不了书,所以在 AI 眼里,他们的声音无足轻重。而我的声音,如今稍微有了点分量。
Today, I can write a book. My parents weren't able to write a book, so their voice doesn't matter to AI. My voice now matters a little bit.
事实上,哈佛把这称作 WEIRD。这里的 weird 不是“古怪”的意思,而是说:AI 是西方化的、受过教育的、工业化的、富裕的、民主的。
As a matter of fact, Harvard calls that WEIRD. And by weird, they don't mean bizarre: AI is Westernized, Educated, Industrialized, Rich, and Democratic.
所以,AI 正在向我们所有人“讲授”这个世界。可它讲的并不是世界本身,而是那 8% 到 12% 的人、那个特定阶层的视角。这就是为什么我说,AI 并不代表人类。
So AI now teaches the world to the rest of us. But it's not the world they're teaching; it's the perspective of that 8 to 12 percent, of that specific class. That's why I'm telling you that AI is not representative of humanity.
不过,我们也有一线希望。这线希望是中国:中国有了自己的大语言模型,为世界提供了另一重视角。
Now, we do have a silver lining. The silver lining is China: China having its own large language models, and giving another perspective of the world.
于是又回到那个主题:你哪里都不属于,就必须逼自己从不同角度看问题。这恰恰是我们对 AI 的需要。
So we come back to that idea: you don't belong, and you need to force yourself to see a problem from different angles. Well, that's exactly what we need with AI.
我们需要中国的大语言模型,也需要尼日利亚的、印度的、欧洲的,还需要把这一切融汇在一起。
We need Chinese large language models. We need a Nigerian one, an Indian one, a European one. And we need all of that to be mixed.
我们拥有足够的算力来处理所有这些信息,构建一个更有层次的世界。而不是非善即恶。这不是好莱坞电影,我们得放下那一套了。
We have the compute available to process all that information and have a more nuanced world. Not good versus evil. This is not a Hollywood movie; we've got to stop with that.
想想吧:我们花了整整四十年、四十年去妖魔化穆斯林。到了今天,我们出兵杀他们、杀平民,就变得轻而易举。
Think about it: we spent 40 years, 40 years, demonizing Muslims. And today, it's very easy for us to send the troops and kill them. Kill civilians.
当然,911 是骇人的惨剧,三四千人惨死,我们理应予以最严厉的谴责。
Sure, September 11 was a horrible thing. Three to four thousand people were killed, horribly, and we should really condemn it.
可在那之后,是一百万伊拉克平民惨遭屠戮。
But then, a million Iraqi civilians were slaughtered.
然而你去问 AI,它会告诉你:穆斯林世界是暴力的,西方世界是文明的。
Yet if you ask AI, it will tell you the Muslim world is violent, and the Western world is civilized.
