And I said, "Where? Where? I want to go."
And I was like, "Oh, the Amazon. I was just there. It's awesome. National Geographic sent me to Manú National Park, which is in the Peruvian Amazon, but it's a big chunk of rainforest, uncleared, no roads, protected as a national park, one of the most, in fact, biodiverse parks in the world. And when I got in there with my canoe, what did I find, but people. People have been living there for hundreds and thousands of years. People live there, and they don't just float over the jungle. They have a meaningful relationship with the landscape. They hunt. They grow crops. They domesticate crops. They use the natural resources to build their houses, to thatch their houses. They even make pets out of animals that we consider to be wild animals. These people are there and they're interacting with the environment in a way that's really meaningful and that you can see in the environment.
Now, I was with an anthropologist on this trip, and he told me, as we were floating down the river, he said, "There are no demographic voids in the Amazon." This statement has really stuck with me, because what it means is that the whole Amazon is like this. There's people everywhere. And many other tropical forests are the same, and not just tropical forests. People have influenced ecosystems in the past, and they continue to influence them in the present, even in places where they're harder to notice.
So, if all of the definitions of nature that we might want to use that involve it being untouched by humanity or not having people in it, if all of those actually give us a result where we don't have any nature, then maybe they're the wrong definitions. Maybe we should define it by the presence of multiple species, by the presence of a thriving life.
Now, if we do it that way, what do we get? Well, it's this kind of miracle. All of a sudden, there's nature all around us. All of a sudden, we see this Monarch caterpillar munching on this plant, and we realize that there it is, and it's in this empty lot in Chattanooga. And look at this empty lot. I mean, there's, like, probably, a dozen, minimum, plant species growing there, supporting all kinds of insect life, and this is a completely unmanaged space, a completely wild space. This is a kind of wild nature right under our nose, that we don't even notice.
And there's an interesting little paradox, too. So this nature, this kind of wild, untended part of our urban, peri-urban, suburban agricultural existence that flies under the radar, it's arguably more wild than a national park, because national parks are very carefully managed in the 21st century. Crater Lake in southern Oregon, which is my closest national park, is a beautiful example of a landscape that seems to be coming out of the past. But they're managing it carefully. One of the issues they have now is white bark pine die-off. White bark pine is a beautiful, charismatic -- I'll say it's a charismatic megaflora that grows up at high altitude -- and it's got all these problems right now with disease. There's a blister rust that was introduced, bark beetle. So to deal with this, the park service has been planting rust-resistant white bark pine seedlings in the park, even in areas that they are otherwise managing as wilderness. And they're also putting out beetle repellent in key areas as I saw last time I went hiking there. And this kind of thing is really much more common than you would think. National parks are heavily managed. The wildlife is kept to a certain population size and structure. Fires are suppressed. Fires are started. Non-native species are removed. Native species are reintroduced. And in fact, I took a look, and Banff National Park is doing all of the things I just listed: suppressing fire, having fire, radio-collaring wolves, reintroducing bison. It takes a lot of work to make these places look untouched.
And in a further irony, these places that we love the most are the places that we love a little too hard, sometimes. A lot of us like to go there, and because we're managing them to be stable in the face of a changing planet, they often are becoming more fragile over time.
Which means that they're the absolute worst places to take your children on vacation, because you can't do anything there. You can't climb the trees. You can't fish the fish. You can't make a campfire out in the middle of nowhere. You can't take home the pinecones. There are so many rules and restrictions that from a child's point of view, this is, like, the worst nature ever. Because children don't want to hike through a beautiful landscape for five hours and then look at a beautiful view. That's maybe what we want to do as adults, but what kids want to do is hunker down in one spot and just tinker with it, just work with it, just pick it up, build a house, build a fort, do something like that.
Additionally, these sort of Edenic places are often distant from where people live. And they're expensive to get to. They're hard to visit. So this means that they're only available to the elites, and that's a real problem. The Nature Conservancy did a survey of young people, and they asked them, how often do you spend time outdoors? And only two out of five spent time outdoors at least once a week. The other three out of five were just staying inside. And when they asked them why, what are the barriers to going outside, the response of 61 percent was, "There are no natural areas near my home."
And this is crazy. This is just patently false. I mean, 71 percent of people in the US live within a 10-minute walk of a city park. And I'm sure the figures are similar in other countries. And that doesn't even count your back garden, the urban creek, the empty lot. Everybody lives near nature. Every kid lives near nature. We've just somehow forgotten how to see it. We've spent too much time watching David Attenborough documentaries where the nature is really sexy --
and we've forgotten how to see the nature that is literally right outside our door, the nature of the street tree.
So here's an example: Philadelphia. There's this cool elevated railway that you can see from the ground, that's been abandoned. Now, this may sound like the beginning of the High Line story in Manhattan, and it's very similar, except they haven't developed this into a park yet, although they're working on it. So for now, it's still this little sort of secret wilderness in the heart of Philadelphia, and if you know where the hole is in the chain-link fence, you can scramble up to the top and you can find this completely wild meadow just floating above the city of Philadelphia. Every single one of these plants grew from a seed that planted itself there. This is completely autonomous, self-willed nature. And it's right in the middle of the city. And they've sent people up there to do sort of biosurveys, and there are over 50 plant species up there. And it's not just plants. This is an ecosystem, a functioning ecosystem. It's creating soil. It's sequestering carbon. There's pollination going on. I mean, this is really an ecosystem.
So scientists have started calling ecosystems like these "novel ecosystems," because they're often dominated by non-native species, and because they're just super weird. They're just unlike anything we've ever seen before. For so long, we dismissed all these novel ecosystems as trash. We're talking about regrown agricultural fields, timber plantations that are not being managed on a day-to-day basis, second-growth forests generally, the entire East Coast, where after agriculture moved west, the forest sprung up. And of course, pretty much all of Hawaii, where novel ecosystems are the norm, where exotic species totally dominate. This forest here has Queensland maple, it has sword ferns from Southeast Asia. You can make your own novel ecosystem, too. It's really simple. You just stop mowing your lawn.
Ilkka Hanski was an ecologist in Finland, and he did this experiment himself. He just stopped mowing his lawn, and after a few years, he had some grad students come, and they did sort of a bio-blitz of his backyard, and they found 375 plant species, including two endangered species.
So when you're up there on that future High Line of Philadelphia, surrounded by this wildness, surrounded by this diversity, this abundance, this vibrance, you can look over the side and you can see a local playground for a local school, and that's what it looks like. These children have, that -- You know, under my definition, there's a lot of the planet that counts as nature, but this would be one of the few places that wouldn't count as nature. There's nothing there except humans, no other plants, no other animals. And what I really wanted to do was just, like, throw a ladder over the side and get all these kids to come up with me into this cool meadow. In a way, I feel like this is the choice that faces us. If we dismiss these new natures as not acceptable or trashy or no good, we might as well just pave them over. And in a world where everything is changing, we need to be very careful about how we define nature.
In order not to steal it from our children, we have to do two things. First, we cannot define nature as that which is untouched. This never made any sense anyway. Nature has not been untouched for thousands of years. And it excludes most of the nature that most people can visit and have a relationship with, including only nature that children cannot touch. Which brings me to the second thing that we have to do, which is that we have to let children touch nature, because that which is untouched is unloved.
We face some pretty grim environmental challenges on this planet. Climate change is among them. There's others too: habitat loss is my favorite thing to freak out about in the middle of the night. But in order to solve them, we need people -- smart, dedicated people -- who care about nature. And the only way we're going to raise up a generation of people who care about nature is by letting them touch nature.
I have a Fort Theory of Ecology, Fort Theory of Conservation. Every ecologist I know, every conservation biologist I know, every conservation professional I know, built forts when they were kids. If we have a generation that doesn't know how to build a fort, we'll have a generation that doesn't know how to care about nature.
And I don't want to be the one to tell this kid, who is on a special program that takes Philadelphia kids from poor neighborhoods and takes them to city parks, I don't want to be the one to tell him that the flower he's holding is a non-native invasive weed that he should throw away as trash. I think I would much rather learn from this boy that no matter where this plant comes from, it is beautiful, and it deserves to be touched and appreciated.
Thank you.

🔴How I made friends with reality?

I'm going to first tell you something that in my grandmother would've elicited a five-oy alarm: "Oy-oy-oy-oy-oy." And here it is ... are you ready? OK. I have stage IV lung cancer. Oh, I know, "poor me." I don't feel that way. I'm so OK with it. And granted, I have certain advantages -- not everybody can take so cavalier an attitude. I don't have young children. I have a grown daughter who's brilliant and happy and wonderful. I don't have huge financial stress. My cancer isn't that aggressive. It's kind of like the Democratic leadership --
not convinced it can win. It's basically just sitting there, waiting for Goldman Sachs to give it some money.
Oh, and the best thing of all -- I have a major accomplishment under my belt. Yes. I didn't even know it until someone tweeted me a year ago. And here's what they said: "You are responsible for the pussification of the American male."
Not that I can take all the credit, but ...
But what if you don't have my advantages? The only advice I can give you is to do what I did: make friends with reality. You couldn't have a worse relationship with reality than I did. From the get-go, I wasn't even attracted to reality. If they'd had Tinder when I met reality, I would have swiped left and the whole thing would have been over.
And reality and I -- we don't share the same values, the same goals --
To be honest, I don't have goals; I have fantasies. They're exactly like goals but without the hard work.
I'm not a big fan of hard work, but you know reality -- it's either push, push, push, push, push through its agent, the executive brain function -- one of the "yays" of dying: my executive brain function won't have me to kick around anymore.
But something happened that made me realize that reality may not be reality. So what happened was, because I basically wanted reality to leave me alone -- but I wanted to be left alone in a nice house with a Wolf range and Sub-Zero refrigerator ... private yoga lessons -- I ended up with a development deal at Disney. And one day I found myself in my new office on Two Dopey Drive --
And I'm staring at the present they sent me to celebrate my arrival -- not the Lalique vase or the grand piano I've heard of other people getting, but a three-foot-tall, stuffed Mickey Mouse
with a catalog, in case I wanted to order some more stuff that didn't jibe with my aesthetic.
And when I looked up in the catalog to see how much this three-foot-high mouse cost, here's how it was described ... "Life-sized."
And that's when I knew. Reality wasn't "reality." Reality was an imposter.
So I dived into quantum physics and chaos theory to try to find actual reality, and I've just finished a movie -- yes, finally finished -- about all that, so I won't go into it here, and anyway, it wasn't until after we shot the movie, when I broke my leg and then it didn't heal, so then they had to do another surgery a year later, and then that took a year -- two years in a wheelchair, and that's when I came into contact with actual reality: limits.
Those very limits I'd spent my whole life denying and pushing past and ignoring were real, and I had to deal with them, and they took imagination, creativity and my entire skill set. It turned out I was great at actual reality. I didn't just come to terms with it, I fell in love. And I should've known, given my equally shaky relationship with the zeitgeist ... I'll just say, if anyone is in the market for a Betamax
I should have known that the moment I fell in love with reality, the rest of the country would decide to go in the opposite direction.
But I'm not here to talk about Trump or the alt-right or climate-change deniers or even the makers of this thing, which I would have called a box, except that right here, it says, "This is not a box."
They're gaslighting me.
1
But what I do want to talk about is a personal challenge to reality that I take personally, and I want to preface it by saying that I absolutely love science. I have this -- not a scientist myself -- but an uncanny ability to understand everything about science, except the actual science --
which is math. But the most outlandish concepts make sense to me. The string theory; the idea that all of reality emanates from the vibrations of these teeny -- I call it "The Big Twang."
Wave-particle duality: the idea that one thing can manifest as two things ... you know? That a photon can manifest as a wave and a particle coincided with my deepest intuitions that people are good and bad, ideas are right and wrong. Freud was right about penis envy and he was wrong about who has it.
And then there's this slight variation on that, which is reality looks like two things, but it turns out to be the interaction of those two things, like space -- time, mass -- energy and life and death. So I don't understand -- I simply just don't understand the mindset of people who are out to "defeat death" and "overcome death." How do you do that? How do you defeat death without killing off life? It doesn't make sense to me.
I also have to say, I find it incredibly ungrateful. I mean, you're given this extraordinary gift -- life -- but it's as if you had asked Santa for a Rolls-Royce Silver Shadow and you had gotten a salad spinner instead. You know, it's the beef -- the beef with it is that it comes with an expiration date. Death is the deal breaker. I don't get that. I don't understand -- to me, it's disrespectful. It's disrespectful to nature. The idea that we're going to dominate nature, we're going to master nature, nature is too weak to withstand our intellect -- no, I don't think so. I think if you've actually read quantum physics as I have -- well, I read an email from someone who'd read it, but --
You have to understand that we don't live in Newton's clockwork universe anymore. We live in a banana peel universe, and we won't ever be able to know everything or control everything or predict everything. Nature is like a self-driving car. The best we can be is like the old woman in that joke -- I don't know if you've heard it. An old woman is driving with her middle-aged daughter in the passenger seat, and the mother goes right through a red light. And the daughter doesn't want to say anything that makes it sound like, "You're too old to drive," so she didn't say anything. And then the mother goes through a second red light, and the daughter, as tactfully as possible, says, "Mom, are you aware that you just went through two red lights?" And the mother says, "Oh, am I driving?"
So ... and now, I'm going to take a mental leap, which is easy for me because I'm the Evel Knievel of mental leaps; my license plate says, "Cogito, ergo zoom." I hope you're willing to come with me on this, but my real problem with the mindset that is so out to defeat death is if you're anti-death, which to me translates as anti-life, which to me translates as anti-nature, it also translates to me as anti-woman, because women have long been identified with nature. And my source on this is Hannah Arendt, the German philosopher who wrote a book called "The Human Condition." And in it, she says that classically, work is associated with men. Work is what comes out of the head; it's what we invent, it's what we create, it's how we leave our mark upon the world. Whereas labor is associated with the body. It's associated with the people who perform labor or undergo labor. So to me, the mindset that denies that, that denies that we're in sync with the biorhythms, the cyclical rhythms of the universe, does not create a hospitable environment for women or for people associated with labor, which is to say, people that we associate as descendants of slaves, or people who perform manual labor.
So here's how it looks from a banana-peel-universe point of view, from my mindset, which I call "Emily's universe." First of all, I am incredibly grateful for life, but I don't want to be immortal. I have no interest in having my name live on after me. In fact, I don't want it to, because it's been my observation that no matter how nice and how brilliant or how talented you are, 50 years after you die, they turn on you.
And I have actual proof of that. A headline from the Los Angeles Times: "Anne Frank: Not so nice after all."
Plus, I love being in sync with the cyclical rhythms of the universe. That's what's so extraordinary about life: it's a cycle of generation, degeneration, regeneration. "I" am just a collection of particles that is arranged into this pattern, then will decompose and be available, all of its constituent parts, to nature, to reorganize into another pattern. To me, that is so exciting, and it makes me even more grateful to be part of that process.
You know, I look at death now from the point of view of a German biologist, Andreas Weber, who looks at it as part of the gift economy. You're given this enormous gift, life, you enrich it as best you can, and then you give it back. And, you know, Auntie Mame said, "Life is a banquet" -- well, I've eaten my fill. I have had an enormous appetite for life, I've consumed life, but in death, I'm going to be consumed. I'm going into the ground just the way I am, and there, I invite every microbe and detritus-er and decomposer to have their fill. I think they'll find me delicious.
So the best thing about my attitude, I think, is that it's real. You can see it. You can observe it. It actually happens. Well, maybe not my enriching the gift, I don't know about that -- but my life has certainly been enriched by other people. By TED, which introduced me to a whole network of people who have enriched my life, including Tricia McGillis, my website designer, who's working with my wonderful daughter to take my website and turn it into something where all I have to do is write a blog. I don't have to use the executive brain function ... Ha, ha, ha, I win!
And I am so grateful to you. I don't want to say "the audience," because I don't really see it as we're two separate things. I think of it in terms of quantum physics, again. And, you know, quantum physicists are not exactly sure what happens when the wave becomes a particle. There are different theories -- the collapse of the wave function, decoherence -- but they're all agreed on one thing: that reality comes into being through an interaction. (Voice breaking) So do you. And every audience I've ever had, past and present. Thank you so much for making my life real.

🔴The transformative power of video games

Hello. My name is Herman, and I've always been struck by how the most important, impactful, tsunami-like changes to our culture and our society always come from those things that we least think are going to have that impact.
I mean, as a computer scientist, I remember when Facebook was just image-sharing in dorm rooms, and depending upon who you ask, it's now involved in toppling elections. I remember when cryptocurrency or automated trading were sort of ideas by a few renegades in the financial institutions in the world for automated trading, or online, for cryptocurrency, and they're now coming to quickly shape the way that we operate. And I think each of you can recall that moment where one of these ideas felt like some ignorable, derisive thing, and suddenly, oh, crap, the price of Bitcoin is what it is. Or, oh, crap, guess who's been elected.
The reality is that, you know, from my perspective, I think that we're about to encounter that again. And I think one of the biggest, most impactful changes in the way we live our lives, to the ways we're educated, probably even to how we end up making an income, is about to come not from AI, not from space travel or biotech -- these are all very important future inventions -- but in the next five years, I think it's going to come from video games.
So that's a bold claim, OK. I see some skeptical faces in the audience. But if we take a moment to try to look at what video games are already becoming in our lives today, and what just a little bit of technological advancement is about to create, it starts to become more of an inevitability. And I think the possibilities are quite electrifying. So let's just take a moment to think about scale.
I mean, there's already 2.6 billion people who play games. And the reality is that's a billion more than five years ago. A billion more people in that time. No religion, no media, nothing has spread like that. And there's likely to be a billion more when Africa and India gain the infrastructure to sort of fully realize the possibilities of gaming. But what I find really special is -- and this often shocks a lot of people -- is that the average age of a gamer, like, have a guess, think about it. It's not six, it's not 18, it's not 12. It's 34. [Average age of an American gamer] It's older than me. And that tells us something, that this isn't entertainment for children anymore. This is already a medium like literature or anything else that's becoming a fundamental part of our lives.
One stat I like is that people who generally picked up gaming in the last sort of 15, 20 years generally don't stop. Something changed in the way that this medium is organized. And more than that, it's not just play anymore, right? You've heard some examples today, but people are earning an income playing games. And not in the obvious ways. Yes, there's e-sports, there's prizes, there's the opportunity to make money in a competitive way. But there's also people earning incomes modding games, building content in them, doing art in them. I mean, there's something at a scale akin to the Florentine Renaissance, happening on your kid's iPhone in your living room. And it's being ignored.
Now, what's even more exciting for me is what's about to happen. And when you think about gaming, you're probably already imagining that it features these massive, infinite worlds, but the truth is, games have been deeply limited for a very long time in a way that kind of we in the industry have tried very hard to cover up with as much trickery as possible. The metaphor I like to use, if you'd let me geek out for a moment, is the notion of a theater. For the last 10 years, games have massively advanced the visual effects, the physical immersion, the front end of games. But behind the scenes, the actual experiential reality of a game world has remained woefully limited. I'll put that in perspective for a moment. I could leave this theater right now, I could do some graffiti, get in a fight, fall in love. I might actually do all of those things after this, but the point is that all of that would have consequence. It would ripple through reality -- all of you could interact with that at the same time. It would be persistent. And those are very important qualities to what makes the real world real.
Now, behind the scenes in games, we've had a limit for a very long time. And the limit is, behind the visuals, the actual information being exchanged between players or entities in a single game world has been deeply bounded by the fact that games mostly take place on a single server or a single machine. Even The World of Warcraft is actually thousands of smaller worlds. When you hear about concerts in Fortnite, you're actually hearing about thousands of small concerts. You know, individual, as was said earlier today, campfires or couches. There isn't really this possibility to bring it all together. Let's take a moment to just really understand what that means. When you look at a game, you might see this, beautiful visuals, all of these things happening in front of you.
But behind the scenes in an online game, this is what it looks like. To a computer scientist, all you see is just a little bit of information being exchanged by a tiny handful of meaningful entities or objects. You might be thinking, "I've played in an infinite world." Well it's more that you've played on a treadmill. As you've been walking through that world, we've been cleverly causing the parts of it that you're not in to vanish, and the parts of it in front of you to appear. A good trick, but not the basis for the revolution that I promised you in the beginning of this talk.
But the reality is, for those of you that are passionate gamers and might be excited about this, and for those of you that are afraid and may not be, all of that is about to change. Because finally, the technology is in place to go well beyond the limits that we've previously seen. I've dedicated my career to this, there are many others working on the problem -- I'd hardly take credit for it myself, but we're at the point now where we can finally do this impossible hard thing of weaving together thousands of disparate machines into single simulations that are convenient enough to not be one-offs, but to be buildable by anybody. And to be at the point where we can start to experience those things that we can't yet fathom.
Let's just take a moment to visualize that. I'm talking about not individual little simulations but a massive possibility of huge networks of interaction. Massive global events that can happen inside that. Things that even in the real world become challenging to produce at that kind of scale. And I know some of you are gamers, so I'm going to show you some footage of some things that I'm pretty sure I'm allowed to do, from some of our partners. TED and me had a back-and-forth on this. These are a few things that not many people have seen before, some new experiences powered by this type of technology. I'll just [take] a moment to show you some of this stuff.
This is a single game world with thousands of simultaneous people participating in a conflict. It also has its own ecosystem, its own sense of predator and prey. Every single object you see here is simulated in some way. This is a game being built by one of the biggest companies in the world, NetEase, a huge Chinese company. And they've made an assistant creative simulation where groups of players can cocreate together, across multiple devices, in a world that doesn't vanish when you're done. It's a place to tell stories and have adventures. Even the weather is simulated. And that's kind of awesome.
And this is my personal favorite. This is a group of people, pioneers in Berlin, a group called Klang Games, and they're completely insane, and they'll love me for saying that. And they found a way to model, basically, an entire planet. They're going to have a simulation with millions of non-player characters and players engaging. They actually grabbed Lawrence Lessig to help understand the political ramifications of the world they're creating.
This is the sort of astounding set of experiences, well beyond what we might have imagined, that are now going to be possible. And that's just the first step in this technology.
So if we step beyond that, what happens? Well, computer science tends to be all exponential, once we crack the really hard problems. And I'm pretty sure that very soon, we're going to be in a place where we can make this type of computational power look like nothing. And when that happens, the opportunities ...
It's worth taking a moment to try to imagine what I'm talking about here. Hundreds of thousands or millions of people being able to coinhabit the same space. The last time any of us as a species had the opportunity to build or do something together with that may people was in antiquity. And the circumstances were less than optimal, shall we say. Mostly conflicts or building pyramids. Not necessarily the best thing for us to be spending our time doing. But if you bring together that many people, the kind of shared experience that can create ... I think it exercises a social muscle in us that we've lost and forgotten.
Going even beyond that, I want to take a moment to think about what it means for relationships, for identity. If we can give each other worlds, experiences at scale where we can spend a meaningful amount of our time, we can change what it means to be an individual. We can go beyond a single identity to a diverse set of personal identities. The gender, the race, the personality traits you were born with might be something you want to experiment differently with. You might be someone that wants to be more than one person. We all are, inside, multiple people. We rarely get the opportunity to flex that.
It's also about empathy. I have a grandmother who I have literally nothing in common with. I love her to bits, but every story she has begins in 1940 and ends sometime in 1950. And every story I have is like 50 years later. But if we could coinhabit, co-experience things together, that undiminished by physical frailty or by lack of context, create opportunities together, that changes things, that bonds people in different ways. I'm struck by how social media has amplified our many differences, and really made us more who we are in the presence of other people. I think games could really start to create an opportunity for us to empathize again. To have shared adversity, shared opportunity.
I mean, statistically, at this moment in time, there are people who are on the opposite sides of a conflict, who have been matchmade together into a game and don't even know it. That's an incredible opportunity to change the way we look at things.
Finally, for those of you who perhaps are more cynical about all of this, who maybe don't think that virtual worlds and games are your cup of tea. There's a reality you have to accept, and that is that the economic impact of what I'm talking about will be profound. Right now, thousands of people have full-time jobs in gaming. Soon, it will be millions of people. Wherever there's a mobile phone, there will be a job. An opportunity for something that is creative and rich and gives you an income, no matter what country you're in, no matter what skills or opportunities you might think you have. Probably the first dollar most kids born today make might be in a game. That will be the new paper route, that will be the new opportunity for an income at the earliest time in your life.
So I kind of want to end with almost a plea, really, more than thoughts. A sense of, I think, how we need to face this new opportunity a little differently to some we have in the past. It's so hypocritical for yet another technologist to stand up on stage and say, "The future will be great, technology will fix it." And the reality is, this is going to have downsides. But those downsides will only be amplified if we approach, once again, with cynicism and derision, the opportunities that this presents. The worst thing that we could possibly do is let the same four or five companies end up dominating yet another adjacent space.
Because they're not just going to define how and who makes money from this. The reality is, we're now talking about defining how we think, what the rules are around identity and collaboration, the rules of the world we live in. This has got to be something we all own, we all cocreate.
So, my final plea is really to those engineers, those scientists, those artists in the audience today. Maybe some of you dreamed of working on space travel. The reality is, there are worlds you can build right here, right now, that can transform people's lives. There are still huge technological frontiers that need to be overcome here, akin to those we faced when building the early internet. All the technology behind virtual worlds is different. So, my plea to you is this. Let's engage, let's all engage, let's actually try to make this something that we shape in a positive way, rather than once again have be done to us.
Thank you.
