1 99:59:59,999 --> 99:59:59,999 So imagine, you're in the supermarket, 2 99:59:59,999 --> 99:59:59,999 you're buying some groceries, 3 99:59:59,999 --> 99:59:59,999 and you get given the option 4 99:59:59,999 --> 99:59:59,999 for a plastic or a paper shopping bag. 5 99:59:59,999 --> 99:59:59,999 Which one do you choose if you want to do 6 99:59:59,999 --> 99:59:59,999 the right thing by the environment? 7 99:59:59,999 --> 99:59:59,999 Most people do pick the paper. 8 99:59:59,999 --> 99:59:59,999 Okay, let's think of why. 9 99:59:59,999 --> 99:59:59,999 It's brown to start with. 10 99:59:59,999 --> 99:59:59,999 Therefore, it must be good for the environment. 11 99:59:59,999 --> 99:59:59,999 It's biodegradable. It's reusable. 12 99:59:59,999 --> 99:59:59,999 In some cases, it's recyclable. 13 99:59:59,999 --> 99:59:59,999 So when people are looking at the plastic bag, 14 99:59:59,999 --> 99:59:59,999 it's likely they're thinking of something like this, 15 99:59:59,999 --> 99:59:59,999 which we all know is absolutely terrible 16 99:59:59,999 --> 99:59:59,999 and we should be avoiding at all expenses 17 99:59:59,999 --> 99:59:59,999 these kinds of environmental damages. 18 99:59:59,999 --> 99:59:59,999 But people are often not thinking 19 99:59:59,999 --> 99:59:59,999 of something like this, 20 99:59:59,999 --> 99:59:59,999 which is the other end of the spectrum. 21 99:59:59,999 --> 99:59:59,999 When we produce materials, 22 99:59:59,999 --> 99:59:59,999 we need to extract them from the environment, 23 99:59:59,999 --> 99:59:59,999 and we need a whole bunch of environmental impacts. 24 99:59:59,999 --> 99:59:59,999 You see, what happens is, when we need 25 99:59:59,999 --> 99:59:59,999 to make complex choices, 26 99:59:59,999 --> 99:59:59,999 us humans like really simple solutions, 27 99:59:59,999 --> 99:59:59,999 and so we often ask the simple solutions. 28 99:59:59,999 --> 99:59:59,999 And I work in design. 29 99:59:59,999 --> 99:59:59,999 I advise designers 30 99:59:59,999 --> 99:59:59,999 and innovators around sustainability, 31 99:59:59,999 --> 99:59:59,999 and everyone always says to me, "Oh Leyla, 32 99:59:59,999 --> 99:59:59,999 I just want the eco-materials." 33 99:59:59,999 --> 99:59:59,999 And I say, "Well, that's very complex, 34 99:59:59,999 --> 99:59:59,999 and we'll have to spend four hours talking about 35 99:59:59,999 --> 99:59:59,999 what exactly an eco-material means, 36 99:59:59,999 --> 99:59:59,999 because everything at some point 37 99:59:59,999 --> 99:59:59,999 comes from nature, 38 99:59:59,999 --> 99:59:59,999 and it's how you use the material 39 99:59:59,999 --> 99:59:59,999 that dictates the environmental impact. 40 99:59:59,999 --> 99:59:59,999 So what happens is, we have to rely 41 99:59:59,999 --> 99:59:59,999 on some sort of intuitive framework 42 99:59:59,999 --> 99:59:59,999 when we make decisions. 43 99:59:59,999 --> 99:59:59,999 So I like to call that intuitive framework 44 99:59:59,999 --> 99:59:59,999 our environmental folklore. 45 99:59:59,999 --> 99:59:59,999 Okay, it's either the little voice at the back of your head, 46 99:59:59,999 --> 99:59:59,999 or it's that gut feeling you get 47 99:59:59,999 --> 99:59:59,999 when you've done the right thing, 48 99:59:59,999 --> 99:59:59,999 so when you've picked the paper bag 49 99:59:59,999 --> 99:59:59,999 or when you've bought a fuel-efficient car. 50 99:59:59,999 --> 99:59:59,999 And environmental folklore is a really important thing 51 99:59:59,999 --> 99:59:59,999 because we're trying to do the right thing. 52 99:59:59,999 --> 99:59:59,999 But how do we know if we're actually 53 99:59:59,999 --> 99:59:59,999 reducing the net environmental impacts 54 99:59:59,999 --> 99:59:59,999 that our actions as individuals and as professionals 55 99:59:59,999 --> 99:59:59,999 and as a society are actually having 56 99:59:59,999 --> 99:59:59,999 on the natural environment? 57 99:59:59,999 --> 99:59:59,999 So the thing about environmental folklore is 58 99:59:59,999 --> 99:59:59,999 it tends to be based on our experiences, 59 99:59:59,999 --> 99:59:59,999 the things we've heard from other people. 60 99:59:59,999 --> 99:59:59,999 It doesn't tend to be based on any scientific framework. 61 99:59:59,999 --> 99:59:59,999 And this is really hard, because we live 62 99:59:59,999 --> 99:59:59,999 in incredibly complex systems. 63 99:59:59,999 --> 99:59:59,999 We have the human systems 64 99:59:59,999 --> 99:59:59,999 of how we communicate and interrelate 65 99:59:59,999 --> 99:59:59,999 and have our whole constructed society, 66 99:59:59,999 --> 99:59:59,999 of the industrial systems, 67 99:59:59,999 --> 99:59:59,999 which is essentially the entire economy, 68 99:59:59,999 --> 99:59:59,999 and then all of that has to operate 69 99:59:59,999 --> 99:59:59,999 within the biggest system, 70 99:59:59,999 --> 99:59:59,999 and, I would argue, the most important, 71 99:59:59,999 --> 99:59:59,999 the ecosystem. 72 99:59:59,999 --> 99:59:59,999 And you see, the choices that we make 73 99:59:59,999 --> 99:59:59,999 as an individual, 74 99:59:59,999 --> 99:59:59,999 but the choices that we make 75 99:59:59,999 --> 99:59:59,999 in every single job that we have, 76 99:59:59,999 --> 99:59:59,999 no matter how high or low you are in the pecking order, 77 99:59:59,999 --> 99:59:59,999 has an impact on all of these systems. 78 99:59:59,999 --> 99:59:59,999 And the thing is that we have to find ways 79 99:59:59,999 --> 99:59:59,999 if we're actually going to address sustainability 80 99:59:59,999 --> 99:59:59,999 of interlocking those complex systems 81 99:59:59,999 --> 99:59:59,999 and making better choices that result 82 99:59:59,999 --> 99:59:59,999 in net environmental gains. 83 99:59:59,999 --> 99:59:59,999 What we need to do is we need to learn 84 99:59:59,999 --> 99:59:59,999 to do more with less. 85 99:59:59,999 --> 99:59:59,999 We have an increasing population, 86 99:59:59,999 --> 99:59:59,999 and everybody likes their mobile phones, 87 99:59:59,999 --> 99:59:59,999 especially in this situation here. 88 99:59:59,999 --> 99:59:59,999 So we need to find innovative ways of solving 89 99:59:59,999 --> 99:59:59,999 some of these problems that we face. 90 99:59:59,999 --> 99:59:59,999 And that's where this process called 91 99:59:59,999 --> 99:59:59,999 life cycle thinking comes in. 92 99:59:59,999 --> 99:59:59,999 So essentially, everything that is created 93 99:59:59,999 --> 99:59:59,999 goes through a series of life cycle stages, 94 99:59:59,999 --> 99:59:59,999 and we use this scientific process 95 99:59:59,999 --> 99:59:59,999 called life cycle assessment, 96 99:59:59,999 --> 99:59:59,999 or in America, you guys say life cycle analysis, 97 99:59:59,999 --> 99:59:59,999 in order to have a clearer picture of how 98 99:59:59,999 --> 99:59:59,999 everything that we do in the technical part of those systems 99 99:59:59,999 --> 99:59:59,999 affects the natural environment. 100 99:59:59,999 --> 99:59:59,999 So we go all the way back 101 99:59:59,999 --> 99:59:59,999 to the extraction of raw materials, 102 99:59:59,999 --> 99:59:59,999 and then we look at manufacturing, 103 99:59:59,999 --> 99:59:59,999 we look at packaging and transportation, 104 99:59:59,999 --> 99:59:59,999 use, and end of life, 105 99:59:59,999 --> 99:59:59,999 and at every single one of these stages, 106 99:59:59,999 --> 99:59:59,999 the things that we do 107 99:59:59,999 --> 99:59:59,999 have an interaction with the natural environment, 108 99:59:59,999 --> 99:59:59,999 and we can monitor how that interaction 109 99:59:59,999 --> 99:59:59,999 is actually affecting the systems and services 110 99:59:59,999 --> 99:59:59,999 that make life on earth possible. 111 99:59:59,999 --> 99:59:59,999 And through doing this, 112 99:59:59,999 --> 99:59:59,999 we've learned some absolutely fascinating things. 113 99:59:59,999 --> 99:59:59,999 And we've busted a bunch of myths. 114 99:59:59,999 --> 99:59:59,999 So to start with, 115 99:59:59,999 --> 99:59:59,999 there's a word that's used a lot. 116 99:59:59,999 --> 99:59:59,999 It's used a lot in marketing, 117 99:59:59,999 --> 99:59:59,999 and it's used a lot, I think, in our conversation 118 99:59:59,999 --> 99:59:59,999 when we're talking about sustainability, 119 99:59:59,999 --> 99:59:59,999 and that's the word biodegradability. 120 99:59:59,999 --> 99:59:59,999 Now biodegradability is a material property. 121 99:59:59,999 --> 99:59:59,999 It is not a definition of environmental benefits. 122 99:59:59,999 --> 99:59:59,999 Allow me to explain. 123 99:59:59,999 --> 99:59:59,999 When something natural, 124 99:59:59,999 --> 99:59:59,999 something that's made from a cellulose fiber 125 99:59:59,999 --> 99:59:59,999 like a piece of bread, even, or any food waste, 126 99:59:59,999 --> 99:59:59,999 or even a piece of paper, 127 99:59:59,999 --> 99:59:59,999 when something natural ends up 128 99:59:59,999 --> 99:59:59,999 in the natural environment, it degrades normally. 129 99:59:59,999 --> 99:59:59,999 Its little carbon molecules that it stored up 130 99:59:59,999 --> 99:59:59,999 as it was growing are naturally released 131 99:59:59,999 --> 99:59:59,999 back into the atmosphere as carbon dioxide, 132 99:59:59,999 --> 99:59:59,999 but this is a net situation. 133 99:59:59,999 --> 99:59:59,999 Most natural things 134 99:59:59,999 --> 99:59:59,999 don't actually end up in nature. 135 99:59:59,999 --> 99:59:59,999 Most of the things, the waste that we produce, 136 99:59:59,999 --> 99:59:59,999 end up in landfill. 137 99:59:59,999 --> 99:59:59,999 Landfill is a different environment. 138 99:59:59,999 --> 99:59:59,999 In landfill, those same carbon molecules 139 99:59:59,999 --> 99:59:59,999 degrade in a different way, 140 99:59:59,999 --> 99:59:59,999 because a landfill is anaerobic. 141 99:59:59,999 --> 99:59:59,999 It's tightly compacted and hot. 142 99:59:59,999 --> 99:59:59,999 Those same molecules, they become methane, 143 99:59:59,999 --> 99:59:59,999 and methane is a 25 times more potent 144 99:59:59,999 --> 99:59:59,999 greenhouse gas than carbon dioxide. 145 99:59:59,999 --> 99:59:59,999 So our old lettuces and products 146 99:59:59,999 --> 99:59:59,999 that we have thrown out that are made 147 99:59:59,999 --> 99:59:59,999 out of biodegradable materials, 148 99:59:59,999 --> 99:59:59,999 if they end up in landfill, 149 99:59:59,999 --> 99:59:59,999 contribute to climate change. 150 99:59:59,999 --> 99:59:59,999 You see, there are facilities now 151 99:59:59,999 --> 99:59:59,999 that can actually capture that methane 152 99:59:59,999 --> 99:59:59,999 and generate power, 153 99:59:59,999 --> 99:59:59,999 displacing the need for fossil fuel power, 154 99:59:59,999 --> 99:59:59,999 but we need to be smart about this. 155 99:59:59,999 --> 99:59:59,999 We need to identify how we can start to leverage 156 99:59:59,999 --> 99:59:59,999 these types of things that are already happening 157 99:59:59,999 --> 99:59:59,999 and start to design systems and services 158 99:59:59,999 --> 99:59:59,999 that alleviate these problems. 159 99:59:59,999 --> 99:59:59,999 Because right now, what people do is they turn around and they say, 160 99:59:59,999 --> 99:59:59,999 "Let's ban plastic bags. We'll give people paper 161 99:59:59,999 --> 99:59:59,999 because that is better for the environment." 162 99:59:59,999 --> 99:59:59,999 But if you're throwing it in the bin, 163 99:59:59,999 --> 99:59:59,999 and your local landfill facility 164 99:59:59,999 --> 99:59:59,999 is just a normal one, 165 99:59:59,999 --> 99:59:59,999 then we're having what's called a double negative. 166 99:59:59,999 --> 99:59:59,999 Okay, I'm also a product designer by trade. 167 99:59:59,999 --> 99:59:59,999 I then did social science. 168 99:59:59,999 --> 99:59:59,999 And so I'm absolutely fascinated 169 99:59:59,999 --> 99:59:59,999 by consumer goods and how the consumer goods 170 99:59:59,999 --> 99:59:59,999 that we have kind of become immune to 171 99:59:59,999 --> 99:59:59,999 that fill our lives 172 99:59:59,999 --> 99:59:59,999 have an impact on the natural environment. 173 99:59:59,999 --> 99:59:59,999 And these guys are, like, serial offenders, 174 99:59:59,999 --> 99:59:59,999 and I'm pretty sure everyone in this room 175 99:59:59,999 --> 99:59:59,999 has a refrigerator. 176 99:59:59,999 --> 99:59:59,999 Now America has this amazing ability 177 99:59:59,999 --> 99:59:59,999 to keep growing refrigerator. 178 99:59:59,999 --> 99:59:59,999 In the last few years, they've grown one cubic foot 179 99:59:59,999 --> 99:59:59,999 on average, the standard size 180 99:59:59,999 --> 99:59:59,999 of a refrigerator, 181 99:59:59,999 --> 99:59:59,999 and the problem is, they're so big now, 182 99:59:59,999 --> 99:59:59,999 it's easier for us to buy more food 183 99:59:59,999 --> 99:59:59,999 that we can't eat or find. 184 99:59:59,999 --> 99:59:59,999 I mean, I have things at the back of my refrigerator 185 99:59:59,999 --> 99:59:59,999 that have been there for years, all right? 186 99:59:59,999 --> 99:59:59,999 And so what happens is, we waste more food. 187 99:59:59,999 --> 99:59:59,999 And as I was just explaining, food waste is a problem. 188 99:59:59,999 --> 99:59:59,999 In fact, here in the U.S., 40 percent 189 99:59:59,999 --> 99:59:59,999 of food purchased for the home is wasted. 190 99:59:59,999 --> 99:59:59,999 Half of the world's produced food is wasted. 191 99:59:59,999 --> 99:59:59,999 That's the latest U.N. stats. Up to half of the food. 192 99:59:59,999 --> 99:59:59,999 It's insane. It's 1.3 billion tons of food per annum. 193 99:59:59,999 --> 99:59:59,999 And I blame it on the refrigerator, 194 99:59:59,999 --> 99:59:59,999 well, especially in Western cultures, 195 99:59:59,999 --> 99:59:59,999 because it makes it easier. 196 99:59:59,999 --> 99:59:59,999 I mean, there's a lot of complex systems going on here. 197 99:59:59,999 --> 99:59:59,999 I don't want to make it so simplistic. 198 99:59:59,999 --> 99:59:59,999 But the refrigerator is a serious contributor to this, 199 99:59:59,999 --> 99:59:59,999 and one of the features of it 200 99:59:59,999 --> 99:59:59,999 is the crisper drawer. 201 99:59:59,999 --> 99:59:59,999 You all got crisper drawers? 202 99:59:59,999 --> 99:59:59,999 You know, the draw that you put your lettuces in? 203 99:59:59,999 --> 99:59:59,999 Lettuces have a habit of going soggy 204 99:59:59,999 --> 99:59:59,999 in the crisper drawer, don't they. 205 99:59:59,999 --> 99:59:59,999 Yeah?

We have a population of 22 million. Don't laugh. 352 99:59:59,999 --> 99:59:59,999 And it's been reported that 22 million phones 353 99:59:59,999 --> 99:59:59,999 are in people's drawers. 354 99:59:59,999 --> 99:59:59,999 We need to find ways of solving the problems around this, 355 99:59:59,999 --> 99:59:59,999 because these things are so complicated. 356 99:59:59,999 --> 99:59:59,999 They have so much locked up inside them. 357 99:59:59,999 --> 99:59:59,999 Gold: did you know that it's actually cheaper now 358 99:59:59,999 --> 99:59:59,999 to get gold out of a ton of old mobile phones 359 99:59:59,999 --> 99:59:59,999 than it is out of a ton of gold ore? 360 99:59:59,999 --> 99:59:59,999 There's a number of highly complex and valuable 361 99:59:59,999 --> 99:59:59,999 materials embodied inside these things, 362 99:59:59,999 --> 99:59:59,999 so we need to find ways of encouraging disassembly, 363 99:59:59,999 --> 99:59:59,999 because this is otherwise what happens. 364 99:59:59,999 --> 99:59:59,999 This is a community in Ghana, 365 99:59:59,999 --> 99:59:59,999 and e-waste is reported, or electronic waste 366 99:59:59,999 --> 99:59:59,999 is reported by the U.N. 367 99:59:59,999 --> 99:59:59,999 as being up to 50 million tons trafficked. 368 99:59:59,999 --> 99:59:59,999 This is how they get the gold 369 99:59:59,999 --> 99:59:59,999 and the other valuable materials out. 370 99:59:59,999 --> 99:59:59,999 They burn the electronic waste 371 99:59:59,999 --> 99:59:59,999 in open spaces. 372 99:59:59,999 --> 99:59:59,999 These are communities, and this is happening all over the world. 373 99:59:59,999 --> 99:59:59,999 And because we don't see the ramifications 374 99:59:59,999 --> 99:59:59,999 of the choices that we make as designers, 375 99:59:59,999 --> 99:59:59,999 as businesspeople, as consumers, 376 99:59:59,999 --> 99:59:59,999 then these kinds of externalities happen, 377 99:59:59,999 --> 99:59:59,999 and these are people's lives. 378 99:59:59,999 --> 99:59:59,999 So we need to find smarter, more systems-based, 379 99:59:59,999 --> 99:59:59,999 innovative solutions to these problems, 380 99:59:59,999 --> 99:59:59,999 if we're going to start to live sustainably within this world. 381 99:59:59,999 --> 99:59:59,999 So imagine if, when you bought your mobile phone, 382 99:59:59,999 --> 99:59:59,999 your new one because you replaced your old one 383 99:59:59,999 --> 99:59:59,999 — after 15 to 18 months is the average time 384 99:59:59,999 --> 99:59:59,999 that people replace their phones, by the way — 385 99:59:59,999 --> 99:59:59,999 so if we're going to keep this kind of expedient 386 99:59:59,999 --> 99:59:59,999 mobile phone replacing, then we should 387 99:59:59,999 --> 99:59:59,999 be looking at closing the loop on the systems. 388 99:59:59,999 --> 99:59:59,999 The people who produce these phones, 389 99:59:59,999 --> 99:59:59,999 and some of which I'm sure are in the room right now, 390 99:59:59,999 --> 99:59:59,999 could potentially look at what we call closed-loop systems, 391 99:59:59,999 --> 99:59:59,999 or product system services, 392 99:59:59,999 --> 99:59:59,999 so identifying that there is a market demand 393 99:59:59,999 --> 99:59:59,999 and that market demand's not going to go anywhere, 394 99:59:59,999 --> 99:59:59,999 so you design the product to solve the problem. 395 99:59:59,999 --> 99:59:59,999 Design for disassembly, design for light-weighting. 396 99:59:59,999 --> 99:59:59,999 We heard some of those kinds of strategies 397 99:59:59,999 --> 99:59:59,999 being used in the Tesla Motors car today. 398 99:59:59,999 --> 99:59:59,999 These kinds of approaches are not hard, 399 99:59:59,999 --> 99:59:59,999 but understanding the system 400 99:59:59,999 --> 99:59:59,999 and then looking for viable, market-driven 401 99:59:59,999 --> 99:59:59,999 consumer demand alternatives 402 99:59:59,999 --> 99:59:59,999 is how we can start radically altering 403 99:59:59,999 --> 99:59:59,999 the sustainability agenda, 404 99:59:59,999 --> 99:59:59,999 because I hate to break it to you all: 405 99:59:59,999 --> 99:59:59,999 consumption is the biggest problem. 406 99:59:59,999 --> 99:59:59,999 But design is one of the best solutions. 407 99:59:59,999 --> 99:59:59,999 These kinds of products are everywhere. 408 99:59:59,999 --> 99:59:59,999 By identifying alternative ways of doing things, 409 99:59:59,999 --> 99:59:59,999 we can actually start to innovate, 410 99:59:59,999 --> 99:59:59,999 and I say actually start to innovate. 411 99:59:59,999 --> 99:59:59,999 I'm sure everyone in this room is very innovative. 412 99:59:59,999 --> 99:59:59,999 But in the regards to using sustainability 413 99:59:59,999 --> 99:59:59,999 as a parameter, as a criteria 414 99:59:59,999 --> 99:59:59,999 for fueling systems-based solutions, 415 99:59:59,999 --> 99:59:59,999 because as I've just demonstrated with these simple products, 416 99:59:59,999 --> 99:59:59,999 they're participating in these major problems. 417 99:59:59,999 --> 99:59:59,999 So we need to look across the entire life 418 99:59:59,999 --> 99:59:59,999 of the things that we do. 419 99:59:59,999 --> 99:59:59,999 If you just had paper or plastic, 420 99:59:59,999 --> 99:59:59,999 obviously reusable is far more beneficial, 421 99:59:59,999 --> 99:59:59,999 then the paper is worse, 422 99:59:59,999 --> 99:59:59,999 and the paper is worse because it weighs 423 99:59:59,999 --> 99:59:59,999 four to 10 times more than the plastic, 424 99:59:59,999 --> 99:59:59,999 and when we actually compare, from a life cycle perspective, 425 99:59:59,999 --> 99:59:59,999 a kilo of plastic and a kilo of paper, 426 99:59:59,999 --> 99:59:59,999 the paper is far better, 427 99:59:59,999 --> 99:59:59,999 but the functionality of a plastic or a paper bag 428 99:59:59,999 --> 99:59:59,999 to carry your groceries home 429 99:59:59,999 --> 99:59:59,999 is not done with a kilo of each material. 430 99:59:59,999 --> 99:59:59,999 It's done with a very small amount of plastic 431 99:59:59,999 --> 99:59:59,999 and quite a lot more paper. 432 99:59:59,999 --> 99:59:59,999 Because functionality defines environmental impact, 433 99:59:59,999 --> 99:59:59,999 and I said earlier that the designers always ask me for the eco-materials. 434 99:59:59,999 --> 99:59:59,999 I say, you know, there's only a few materials 435 99:59:59,999 --> 99:59:59,999 that you should completely avoid. 436 99:59:59,999 --> 99:59:59,999 The rest of them, it's all about application, 437 99:59:59,999 --> 99:59:59,999 and at the end of the day, everything we design and produce in the economy 438 99:59:59,999 --> 99:59:59,999 or buy as consumers is done so for function. 439 99:59:59,999 --> 99:59:59,999 We want something, therefore we buy it. 440 99:59:59,999 --> 99:59:59,999 So breaking things back down and delivering 441 99:59:59,999 --> 99:59:59,999 smartly, elegantly, sophisticated solutions 442 99:59:59,999 --> 99:59:59,999 that take into consideration the entire system 443 99:59:59,999 --> 99:59:59,999 and the entire life of the thing, everything, 444 99:59:59,999 --> 99:59:59,999 all the way back to the extraction through to the end of life, 445 99:59:59,999 --> 99:59:59,999 we can start to actually find really innovative solutions. 446 99:59:59,999 --> 99:59:59,999 And I'll just leave you with one very quick thing 447 99:59:59,999 --> 99:59:59,999 that a designer said to me recently who I work with, 448 99:59:59,999 --> 99:59:59,999 a senior designer, I said, 449 99:59:59,999 --> 99:59:59,999 "How come you're not doing sustainability? 450 99:59:59,999 --> 99:59:59,999 You know, I know you know this." 451 99:59:59,999 --> 99:59:59,999 And he said, "Well, recently I pitched a sustainability project to a client, 452 99:59:59,999 --> 99:59:59,999 and turned and he said to me, 453 99:59:59,999 --> 99:59:59,999 'I know it's going to cost less, 454 99:59:59,999 --> 99:59:59,999 I know it's going to sell more, 455 99:59:59,999 --> 99:59:59,999 but we're not pioneers, because pioneers have arrows in their backs.'" 456 99:59:59,999 --> 99:59:59,999 I think we've got a roomful of pioneers, 457 99:59:59,999 --> 99:59:59,999 and I hope there are far more pioneers out there, 458 99:59:59,999 --> 99:59:59,999 because we need to solve these problems. 459 99:59:59,999 --> 99:59:59,999 Thank you. 460 99:59:59,999 --> 99:59:59,999 (Applause)
