    When you open Pandora's box of bad ideas, clearly the sky's the limit. So let's keep pushing it. I got three minutes.当你打开“坏点子”的潘多拉魔盒时，很明显，没有什么是不能尝试的。所以让我们继续往前推。我还有三分钟。 This is a big fruit loop. I don't -- there's not much else to say. It's real. It's about the size of a dinner plate. It takes a lot of milk to put down, but I assure you, it's just as good as the original.这是一个巨大的麦圈。我没什么别的好说的。它是真的，大小差不多有一只餐盘那么大。需要很多牛奶才能吃下去，但我保证，它的味道和原版一样好。 This is what we call an Alexagate. It's an electronics device armed with seven ultrasonic speakers at its base that blasts white noise into the mic of any Alexa device to keep it from eavesdropping on you when you're not using it.这是我们称之为 Alexagate 的东西。它是一种电子设备，底部装有七个超声波扬声器，会向 Alexa 设备的麦克风发射白噪音，从而防止 Alexa 在你不用的时候偷听你。 And then this one is a life-size sculpture that keeps track of and counts the number of times anyone has touched it. Because if you ever go to a gallery or museum, you know you're not supposed to touch the art. So this is supposed to discourage people touching the art.然后这是一个真人大小的雕塑，它会记录并统计每个人触碰它的次数。因为如果你去过美术馆或博物馆，你就知道艺术品是不能随便碰的。而这个作品的目的，就是让人们更不敢去碰艺术品。 Right. Actually, I wanted to wrap up the story about the car because it is real. If you take a second later, it's parked outside. It's here on the loop, so go find it. The car was real. The 5,000 keys were real. We released this to the world in the fall of 2022, and for the following nine months, we actually got to watch this thing change hands hundreds, if not thousands of times, mostly via very peaceful communal meetups and the occasional Grand Theft Auto, which I can't really talk too much about here.好的。实际上，我想把关于那辆车的故事收尾，因为它是真的。等会儿你们可以去看看，它就停在外面，在这附近，所以自己去找吧。车是真的，5,000 把钥匙也是真的。我们在 2022 年秋天把它释放到这个世界里，在接下来的九个月里，我们真的看到它几百次，甚至上千次易手，大多数情况是很和平的社区聚会，当然偶尔也会有“侠盗猎车”的场景出现——不过这个我在这里不能细说。 Over that nine months, it started in New York, it made its way down to Philadelphia, it stayed in Philadelphia for a few days. Grand Theft Auto. And then eventually made its way across the Midwest to the West Coast, where nine months later, I mean, the GPS stopped. We kind of assumed that the project was over. Which is OK. It had a glorious life. But then one day I get a call, and it's a call from a tow pound. And the tow pound is saying, "Hey, we're pretty sure that we have your car because it is registered under your name. But it's such a weird thing because people keep showing up and claiming the car, and they all have keys that work."在那九个月中，它最初出现在纽约，然后一路到费城，在费城停留了几天（期间发生了一次“侠盗猎车”事件）。后来，它又穿过中西部，一直到了西海岸。九个月后，GPS 信号消失了，我们就以为这个项目结束了。没关系，它已经有过辉煌的一生。但某天我接到一个电话，来自一个拖车场。拖车场的人说：“嘿，我们很确定有一辆车是你的，因为它登记在你的名下。但怪事是，不断有人来认领这辆车，而且他们手里都有能开的钥匙。”

    I'm glad you guys think it's funny. I thought it was horrifying. So it wasn't enough for us to just make this. We had to put it in the right place. Does it go outside our studio in Brooklyn? Do we put it in Times Square? My colleagues and I conferred for a little bit, and we realized there's only one place that this thing can ever go. It's Art Basel Miami.很高兴你们觉得这件事好笑。但在我看来，它其实挺可怕的。所以，光是做出这台机器还不够，我们必须把它放在合适的地方。是放在布鲁克林的工作室门口？还是放在时代广场？我和同事们商量了一下，最后发现，这东西唯一合适的地方就是 迈阿密巴塞尔艺术展。 So we take it to Miami. Somehow, we get our way into a gallery and we get into a booth. And on day one, people were actually a little bit hesitant to engage, which I totally get it. It's a little bit shady. It's participatory, I understand. But eventually people would muster up the courage to swipe their card. They would clock in at like 100 dollars in their bank account balance, maybe 1,200 dollars in their bank account balance. By the end of the day, however, someone ended up swiping and clocked in at 12,000 dollars in their bank account balance. And then things started to get a little bit weird.于是我们把它运到迈阿密。不知怎么的，我们成功挤进了一家画廊，弄到一个展位。第一天，人们其实有点犹豫，不太敢尝试，我完全理解——它看起来确实有点阴间操作，而且是参与式的。但最终，人们还是鼓起勇气刷了卡。有人显示账户里有 100 美元，有人显示 1,200 美元。但到了当天结束时，有人刷卡显示账户里有 12,000 美元，事情开始变得微妙起来。 The next day, a famous celebrity DJ named Diplo showed up with his entire entourage, pulled out his debit card, swiped it in the machine, clocked in at three million dollars in his bank account, and shot to the top of the leaderboard. And honestly, the rest is kind of hazy because a crowd amassed so huge around the ATM machine for the following three days that the art fair actually assigned five extra security guards not to protect the ATM machine, but to keep the crowd from bumping into the artworks of the neighboring galleries, which was actually very funny.第二天，一位著名的明星 DJ —— Diplo 带着他的随行人员出现在展会。他掏出借记卡，在机器上刷了一下，结果账户余额显示 三百万美元，直接登上排行榜首位。接下来的情况有点模糊了，因为在随后的三天里，这台 ATM 机前聚集了庞大的人群，以至于艺术博览会不得不额外安排五个保安——不是为了保护这台 ATM 机，而是为了防止人群撞到隔壁画廊的艺术品。这件事本身就很搞笑。 But the most interesting thing that I got to observe here was this unexpected crowd dynamic where when people with astonishingly low bank accounts would swipe their cards, in front of this captive audience, by the way -- and I'm talking really low, like two dollars, concerningly low --但对我来说，最有趣的观察点在于，那些账户余额极低的人刷卡时，意外引发的人群反应。注意，我说的是真的很低，比如只有 两美元，低到令人担心的程度——而且是在一群观众面前公开显示的时候。 They would swipe, they would get ranked at the bottom, and then they would turn around to face the audience, and the audience would lose their minds -- they were cheering and screaming and celebrating and clapping and taking pictures. And it was sincere. It was actually like this wholesome "one of us"-like celebration, which was not anything that we expected.↳他们刷完卡，显示在排行榜最底端，然后转过身面对观众。观众却沸腾了——欢呼、尖叫、庆祝、鼓掌、拍照，而且是发自内心的。那感觉就像一种真诚的“你是我们中的一员”的集体庆祝，这完全出乎我们的意料。 And then to sort of wrap up that week, the funny thing is, a buyer ended up acquiring the ATM machine as a sculpture for a whopping 75,000 dollars. But the funny thing to me is, I don't think that person ever realized that the artwork was not the ATM machine. The artwork was the act of people engaging with the ATM machine. The actual artwork was the relationships that people developed with one another via the ATM machine.到了那周的尾声，最有趣的是，有人最后以 7.5 万美元 的高价把这台 ATM 当作雕塑买走了。但在我看来好笑的是，我不觉得那位买家意识到：真正的艺术作品并不是这台 ATM 机本身，而是人们与这台 ATM 的互动。真正的艺术，是人们通过这台机器彼此之间建立的关系。 See, when we made this thing originally, we were pretty sure it was going to reflect all the worst parts of humanity at Art Basel Miami. But we were wrong. It ended up just being a random crowd of total strangers having a great time together in one big awkward, shared moment of financial transparency.你要知道，当我们最初制作这个东西时，我们确信它会在迈阿密巴塞尔艺术展上揭露人性最糟糕的一面。但我们错了。最后它却成了一个随机的陌生人群体，在一种巨大而尴尬、却共同的“财务透明时刻”中，一起度过了愉快的时光。Oh, I'm not done yet. I'm not done yet. So.哦，我还没讲完呢，我真的还没讲完。好了

    So you've probably figured out by now that I'm not actually here to sell you keys to a car. Today I'm here to talk to you about bad ideas. The kind of ideas that typically die on the vine because reason or work colleagues get in the way. But to me, these are the most exciting ideas because you just never know what might happen.你们大概已经猜到了，我其实不是来卖车钥匙的。今天我想谈的是“坏点子”。这种点子通常在一开始就会被扼杀，因为理性思考或同事的否决会把它挡在路上。但在我看来，这些恰恰是最令人兴奋的点子，因为你永远不知道它们最终会变成什么。 Take these crazy-looking shoes, for example. I think it was like the spring of 2023. My colleagues and I were sketching out the initial prototypes of the Big Red Boot. I remember us being equal parts terrified because, of course, like, who's going to wear these, much less spend money on them? But at the same time, the moment that we put on the initial prototypes ourselves --就拿这双长得很疯狂的鞋子来说吧。我记得那大概是 2023 年的春天，我和同事们在画 Big Red Boot 的最初原型。当时我们既兴奋又害怕，因为很自然的想法就是——谁会穿这种鞋？更别提花钱去买了。但与此同时，当我们自己第一次穿上原型鞋的那一刻—— We were filled with such a chaotic sense of glee that we were like, you know what, we just got to do it. So we committed to making a couple hundred pairs, we priced them at 350 dollars and we just prayed that there would be a few hundred people out there in the world who would spend money on these crazy-looking things.我们心里涌起了一种混乱却强烈的喜悦感，于是我们想：“算了，不管了，干吧！”于是我们决定做几百双，把价格定在 350 美元，只能祈祷世界上会有几百个人愿意花钱买下这种看起来疯狂的东西。 So a week before the drop, we leaked this image through a friend's Instagram account. Again, just hoping that people don't hate it, or even worse, that they don't ignore it. In hindsight, we needn't have worried. The algorithm smiled quite fondly upon the Big Red Boot, and all of a sudden this thing was everywhere. Like, I don't even, I can't even. It's basically like a blur. I don't understand what happened.在正式发售前一周，我们通过一个朋友的 Instagram 账号泄露了这张照片。再次，只是希望人们不要讨厌它，更不要完全无视它。结果回过头来看，我们根本不需要担心。算法很“宠爱”这双 Big Red Boot，突然之间，它火遍了各个角落。老实说，我甚至都说不清楚是怎么回事，一切都像是一阵模糊的旋风。 All of a sudden, people were wearing them courtside at NBA games. I saw Lil Wayne wearing them in amusicvideo. I remember my dad calling me and saying, "Hey, Gabe, there's a professional WWE wrestler wearing your boots on live pay-per-view TV. And he just curb stomped another guy."转眼之间，人们穿着它出现在 NBA 球场边。我看到 Lil Wayne 在一支音乐录影带里穿着它。我还记得我爸打电话告诉我：“嘿，Gabe，有个职业 WWE 摔跤选手在付费直播里穿着你的靴子，他刚刚用它踩翻了另一个人。” It's incredible. And yet we almost didn't do it. This is almost where it ended. Just as an internal project on the cutting room floor. People told us it was not a great business decision. And honestly, I get it. But what started as a bad idea ended up becoming a very interesting idea.这太不可思议了。但我们差点就没做这件事，差点它就停留在内部项目阶段，被放在角落里废弃。很多人告诉我们，这不是一个很好的商业决策。说实话，我理解他们的想法。但一个最初的坏点子，最终却变成了一个非常有趣的点子。 Here's another one. The idea was an ATM machine. Totally normal, functional, operational, extremely legal ATM machine, with one catch. Attached to the ATM machine, as you see, is a digital leaderboard that ranks people based on the amount of money in their remaining account balances.再来一个例子。这次的点子是一台自动取款机。完全正常、功能齐全、合法合规的 ATM 机，但有一个特别之处：在 ATM 机上安装了一块电子排行榜，它会根据用户账户的剩余余额多少来对他们进行排名。

    Good morning everyone. My name is Gabe. I'm a traveling car salesman. So today, I'm here to sell you the keys to this car, this beautiful vintage PT Cruiser. I mean, look at that faux wood side paneling. I'm told it's got turbo. Look. It's a work of art. Trust me.大家早上好。我叫 Gabe。我是一名四处奔波的汽车推销员。今天，我来是要把这辆车的钥匙卖给你们——这辆漂亮的复古 PT Cruiser。看看这仿木纹的侧板，多特别。我听说它还有涡轮增压。看看吧，这就是一件艺术品。相信我。 Now, when I say that I'm selling the keys to this car, I really mean it. I have 5,000 of these keys, and every single last one of them works to that car. You click the key fob once, it unlocks the door, you click it twice, it starts the engine. If you buy any one of these 5,000 keys from me, naturally you get access to the car, but so do 4,999 other people. Whatever happens beyond that is not necessarily my problem. Like I said, I'm just a car salesman.当我说我要卖这辆车的钥匙时，我是认真的。我有 5,000 把这样的钥匙，而且每一把都能打开这辆车。按一次遥控器，它就解锁车门；按两次，它就启动引擎。如果你从我这里买走这 5,000 把钥匙中的任意一把，你当然能开这辆车，但另外 4,999 个人也能开。至于之后会发生什么，那不一定是我的问题。就像我说的，我只是个卖车的。 So you're probably wondering at this point, is this real? Is this guy just making this stuff up? Well, it is real. My name is Gabe, and I'm actually the founder of an art collective based in New York City, called Mschf. These are our logos.你们现在大概会想，这是真的吗？这家伙是不是在胡编乱造？其实，这是真的。我叫 Gabe，我实际上是一个艺术团体的创始人，这个团体位于纽约市，名字叫 Mschf。这些是我们的标志。 Mischief is a bit of a difficult beast to explain, and I'm not going to even try to describe it. Let me give you a couple examples to help paint that picture or confuse you even further.Mschf（恶作剧）是个很难解释的东西，我甚至不打算尝试去定义它。让我给你几个例子，可能能帮你了解一点，或者让你更加困惑。 Handbags. Handbags are really expensive, and incredibly, the smaller they get, the more expensive they become. So a few summers ago, we actually endeavored to make the world's smallest handbag, microscopic, in fact, and somehow it ended up selling at auction for 63,000 dollars, incidentally making it the world's most expensive handbag per volume.手袋。手袋非常昂贵，而且不可思议的是，它们越小，反而越贵。于是几年前的一个夏天，我们真的去尝试制作了世界上最小的手袋——实际上是显微镜下才能看到的大小。结果它竟然在拍卖会上以 63,000 美元成交，顺便也让它成了单位体积价格最贵的手袋。 Here's another one. This is nothing like a handbag. You’ve probably seen those Boston Dynamics Spot dog robots that do TikTok dances with K-pop stars on YouTube. Well, we managed to get one. Instead of making it dance, we strapped a paintball gun to it and we connected it remotely to a website where people could take turns driving it and firing it at an art gallery that we constructed. Boston Dynamics did not like that one very much.再举一个例子。这和手袋完全不同。你们大概见过波士顿动力公司的 Spot 机器人狗吧？在 YouTube 上它们常常和韩流明星一起跳 TikTok 舞。我们设法搞到了一只。但我们没让它跳舞，而是给它绑上一把彩弹枪，然后把它远程连接到一个网站上，让人们轮流操控它，开着它朝我们搭建的艺术画廊射击。波士顿动力公司对这件事可不太高兴。

    Once again, there are many possibilities, all consistent with the data. Some with a lot more metal, some with less. And the difference is a measure of uncertainties. This enables us to know where we should collect information next, where we should drill the next hole, and when we can stop drilling and actually start building a mine.再一次，我们面对的是许多种可能性，而这些可能性都与现有数据相符。有些含有更多金属，有些则更少。而这种差异，正是我们对不确定性的衡量。这让我们能够判断下一步该在哪里收集信息、在哪里钻下一个孔，以及什么时候可以停止钻探，转而真正开始建矿。 To build the mine of the future, we continue to contend with this uncertainty. The industry designs an entire mine based on a single model. We're developing KoBold mine, a mine-design optimization tool that looks at the many possible mine designs against the many possible ore body geometries that we talked about earlier. This enables the best decisions about how much ore we're going to mine, how much waste we're going to produce, how much water we'll use, the cash flows, and so on.为了建造未来的矿山，我们必须继续应对这种不确定性。矿业行业往往是基于单一模型去设计整个矿山。而我们正在开发 KoBold Mine——一种矿山设计优化工具，它会结合我们之前提到的各种可能的矿体几何结构，来对比和评估多种矿山设计方案。这使我们能够做出最优决策，比如将开采多少矿石、会产生多少废料、需要多少用水、现金流如何等等。 This enables the best mine planning decisions about where to put permanent infrastructure, like a shaft. Where the traffic and the tunnels will be placed so we can make efficient decisions, and also how we can maximize the ore and the metal we get and minimize the waste. This technology will move into mine operations to help guide day-to-day decisions for efficiencies.这还使我们能在矿山规划中做出最佳决策，例如永久性基础设施（如竖井）应该放在哪里，交通路线和隧道应该如何布局，以便做出高效的选择。同时还能帮助我们最大化矿石和金属的产出，并将废料最小化。这项技术最终会被应用到矿山运营中，用来指导日常决策，提升效率。 Better predictions don't just mean profitability. It means a safer mine, knowing where the rocks are weaker. It means an environmentally sustainable mine so we can lessen our impact on the environment. And it also means a resilient mine with cash flows to support local communities and businesses through different commodity pricing cycles.更好的预测不仅仅意味着更高的盈利，它还意味着矿山的安全性更高，因为我们能知道哪些地方的岩石更脆弱。它意味着更具环境可持续性的矿山，从而减少对环境的影响。它也意味着矿山具备更强的韧性，能够在不同商品价格周期中，依然保持现金流，进而支持当地社区和企业的发展。 Our Mingomba project in Zambia will be the mine of the future. It's being designed and developed by amazing talent from around the world, including Zambians and Africans like myself. We face the reality that our need for these materials will continue to grow because our lifestyles are going to advance and they're going to demand for it. So the mining industry must ensure they transform so we can become responsible miners and build better mines with better technology. Asante and thank you.我们在赞比亚的明贡巴（Mingomba）项目将成为未来的矿山。它正在由来自世界各地的杰出人才设计和开发，其中也包括像我这样的赞比亚人和非洲人。我们必须面对一个现实：对这些资源的需求将会持续增长，因为我们的生活方式在不断进步，而进步本身就会带来需求。因此，矿业必须确保自身实现转型，让我们能够成为负责任的矿工，利用更先进的技术去建设更好的矿山。Asante！（谢谢）非常感谢大家。

    The incumbent industry deals with this problem by ignoring it. They pick one possible answer and act like the other ones don't exist. And as a result, we design suboptimal mines, make suboptimal decisions, often mining unnecessary material.现有的矿业行业处理这个问题的方式是忽视它。他们只选择一个可能的答案，然后假装其他可能性不存在。结果就是，我们设计出的矿山并不理想，做出的决策也并不优化，经常还会开采大量不必要的物料。 We've invented a different way. We collect all the possibilities consistent with the data measured, and we do this by simulating the physical response of each of the arrangement of rocks. We do this 10,000 times faster by training an AI to learn the relevant physics of the rock beneath, in the time it takes the conventional method to test one. That means we collect better data, we make better predictions of where to look next. So if you had a rock body and a rock body that's denser than material around it, you might drill through the middle of it. But if you have all the hundreds of thousands of possible solutions, the best thing you can do is to collect data where you're the most uncertain and rigorously eliminate as many possibilities as possible. This enables us to maximize the information we get for every dollar we spend, and we do this repeatedly so we can quantify our uncertainties.我们发明了一种不同的方法。我们会收集所有与测量数据相符的可能性，并通过模拟各种岩石组合的物理反应来实现这一点。借助人工智能学习地下岩石相关物理特性，我们的速度比传统方法快上 10,000 倍——在传统方法只能测试一个的时间里，我们能完成成千上万次模拟。这意味着我们能收集到更好的数据，进而对下一步的勘探地点做出更好的预测。比如，如果你发现一个岩体，其密度大于周围的物质，你可能会选择直接在它的中间钻探。但如果你手上有成千上万种可能的解决方案，最明智的做法就是在最不确定的地方收集数据，并尽可能严格地排除掉不可能的情况。这让我们能够最大化每一美元投入所获得的信息，并且我们会不断重复这一过程，从而量化我们的不确定性。 Even after we've made an ore body discovery, we still have to contend with this uncertainty. We have to define the size and shape of this ore body. Let me illustrate how difficult this is. So now, 1,000 meters below your feet, you drilled, you sampled the rock and you determined that it has five percent copper. So now you know, you've got your data point and your observation. Now, I ask you to make a prediction of the concentration of copper of the person sitting next to you.即便我们发现了一个矿体，仍然需要面对这种不确定性。我们必须界定这个矿体的大小和形状。让我来说明这有多困难。假设现在你在脚下 1000 米处钻探，取出了岩石样本，并测定其铜含量为 5%。到这里，你得到了一条数据点和一个观测结果。接下来，我让你预测一下：坐在你旁边的人脚下 1000 米处的铜含量是多少？ What would your prediction be and how confident would you be in your prediction? What about across the room? Think of any person across this room and try to predict 1,000 meters below them. What about in the next building or the next city? This is the vast challenge that we face. We've only sampled a tiny fraction of rock, collected several football fields apart from each other, for which we're trying to make predictions of all the rock properties in between.你的预测会是什么？你对这个预测有多少信心？那么房间另一头呢？想象一下房间那头的某个人，试着预测他脚下 1000 米处的铜含量。那隔壁大楼呢？或者下一座城市呢？这就是我们面临的巨大挑战。我们只采集了极少量的岩石样本，而且这些样本之间相隔相当于几个足球场的距离，却要用这些数据去预测其间所有岩石的属性。 This technology has helped us move fast in Zambia, where I come from, to design and develop a mine based on our predictions for which we've only sampled a tiny fraction of rock.这种技术已经帮助我们在我来自的赞比亚快速推进，仅凭极少量的岩石样本和我们的预测，就能够设计并开发出一座矿山。

    So we need to look deeper. Controversially, we've been taught that these materials will run out. We don't lack ore body deposits. We lack information of where they lie. So if you had a crystal ball, you'd just look into it and start digging out the rocks that are the best and generate the least waste. But we don't have a crystal ball. So the thing that we should do is make predictions of where these materials lie.所以我们需要向更深处探索。一直以来，存在一种争议性的说法：这些矿产资源会枯竭。但实际上，我们并不缺少矿体，我们缺少的是关于它们分布位置的信息。如果你有一个水晶球，只要看一眼，就能直接去挖掘那些品质最好、废料最少的矿石。但现实是我们没有水晶球，所以我们必须依靠预测，推断这些矿产究竟分布在哪里。 My colleagues and I at KoBold are doing what the industry has neglected to do. We aim to predict everything, quantify what we don't know and collect information efficiently. So we're all going to try that right now. I want you to predict 1,000 meters below your feet what the concentration of copper is right where you're sitting. I want you to predict how hard it is, how fractured it is, what's its density? We aim to predict all these things and more. We're developing machine learning technologies that help us predict all of this and rigorously quantify our uncertainties in these predictions. So what does this look like in practice?我和在 KoBold 的同事们正在做这个行业长期忽视的事情。我们的目标是尽可能预测一切，将未知进行量化，并高效地收集信息。现在我想让你们也来尝试一下：试着预测你脚下 1000 米深处的铜浓度是多少？它的硬度如何？裂隙程度怎样？密度又是多少？我们希望能够预测所有这些，甚至更多。为此，我们正在开发机器学习技术，帮助我们完成这些预测，并严格地量化预测中的不确定性。那么，这在实际操作中会是什么样子呢？ When we're exploring for mines, we often fly aircraft thousands of kilometers across the Earth to try collect information such as the Earth's magnetism, its gravitational field, that tells us something about the rocks beneath. But there's a problem. For everything that we're looking at, there are going to be an infinite number of possibilities. And that's because we're building three-dimensional models to fit two-dimensional data. So if a body was smaller and closer to the surface or larger and further away, the measurement would be the same. So this body will also fit the data. And will this one, and this one, and many more.当我们进行矿产勘探时，通常会驾驶飞机在地球上飞行数千公里，以收集数据，例如地球的磁场和引力场信息，这些数据能告诉我们地表下岩石的一些特征。但这里有一个问题：我们观察到的每一个现象，都可能对应无数种可能的解释。这是因为我们用二维数据去构建三维模型。举例来说，如果一个矿体比较小但更接近地表，或者比较大但埋得更深，它们的测量结果可能完全一样。所以，这个矿体可以匹配数据，而另一个也可以，再一个也行，还有更多。

    I was born and raised in Zambia, a country known for its rich copper mining history. Alignment of the stars meant that by birth and by science, I became a miner. Everything we build and use was either grown or mined. From the walls to the windows, the tables and the chairs, your phones, your computers, the stage, my copper earrings and maybe your jewelry.我在赞比亚出生并长大，这个国家以丰富的铜矿开采历史闻名。命运与科学的安排，使我自然而然成为了一名矿工。我们建造和使用的一切，要么是种出来的，要么是挖出来的。从墙壁到窗户，从桌子到椅子，从你的手机到电脑，从舞台到我戴的铜耳环，甚至可能还有你的首饰。 So today when we talk about building a circular economy, we mean we need to electrify everything. Our economies will have cars and trucks, robots, drones and aircraft powered by batteries. Our children will need computers in all schools with equal access, and we'll have data centers full of advanced chips to bring us AI, all sourced by abundant sources of renewable energy. The raw materials we'll need will be recyclable so we can become clean and circular. So that means a lot more lithium, copper, cobalt, nickel and others. So we need to build more than 400 new mines by 2040 for us to become circular.所以今天当我们谈论构建循环经济时，意思是我们必须让一切实现电气化。我们的经济体系将拥有由电池驱动的汽车和卡车、机器人、无人机和飞机。我们的孩子们将在所有学校里都能平等地使用电脑，而我们也会有充满先进芯片的数据中心来为我们带来人工智能，而这一切都将依赖丰富的可再生能源。我们所需要的原材料必须是可回收的，这样我们才能实现清洁和循环。因此，这意味着需要更多的锂、铜、钴、镍以及其他矿物。到 2040 年，我们需要建立超过 400 座新矿山，才能实现循环经济。 But before you can build a mine, you have to find the raw materials. The thing is, today's mining industry leaders are doing too little to advance our qualities of life. In other industries that rely on discovery for growth, like pharmaceuticals and technology, for every dollar they return to shareholders, they spend about a dollar in R and D. In mining, however, for every dollar returned to shareholders, less than a penny is spent in exploration. With such underinvestment, it shouldn't surprise you that the technology used in exploration and mining has barely advanced. In fact, we've gotten ten times worse in the last 30 years at making ore body discoveries.但在你建矿之前，首先必须找到原材料。问题在于，当今的矿业领袖们在提升我们的生活质量方面做得太少。在其他依赖发现推动增长的行业，比如制药业和科技行业，每返还一美元给股东，他们大约会投入一美元用于研发。然而在矿业中，每返还一美元给股东，用于勘探的投入却不到一分钱。在如此严重的投资不足下，你不应该对矿业勘探和开采技术几乎毫无进步感到惊讶。事实上，在过去 30 年里，我们在发现矿体方面的效率已经降低了十倍。 But there's good news. The vast majority of ore deposits are still out there waiting to be found. They're just harder to find. Of all the past mines we know of, they were easy because they were poking out of the surface and they were near the surface.但好消息是，绝大多数矿床仍然存在，正等待我们去发现。只是它们变得更难寻找了。我们已知的那些过去的矿山之所以容易发现，是因为它们要么直接露出地表，要么距离地表非常近。
