Dr. Genevieve Guenther on Twitter: "@GlobalEcoGuy @keya_chatterjee @MichaelEMann @Peters_Glen Hi Jon, my apologies for taking so long to reply to your question. I was solo-parenting today. Anyhow, I have a very long answer for you. One of these days I sho
“Anyhow, I have a very long answer for you. One of these days I should write something about this, but for now lots of tweets…

I think you’re right that aviation has become a domain for virtue signaling. But also I think it still encapsulates real issues that the climate movement must grapple with.

I think there are two different contexts in which to consider these issues. The first is that of the climate movement. What should be expected from people who publicly declare that we must stop emitting GHGs and who try to move our culture and politics to that goal?

My opinion is that people in the climate movement should do everything they can to reduce their own personal emissions.

I am persuaded by the research showing that our doing so increases our public credibility and inoculates us against the charge of moral hypocrisy.

I also believe that reducing our personal emissions gives extra (and necessary) force to our argument that only political action leading to systemic change will solve the climate crisis.

The “we need systemic change” argument is weakened considerably insofar as it seems like self-justification for continuing to enjoy high-carbon pleasures.

Ask your gut: would Greta Thunberg have so galvanized the world if she had flown around Europe to deliver her speeches?

That said, Glen is also clearly right: being able not to fly depends on a number of contingencies. Many people have to fly for work or to see family.

Many climate leaders have to fly. Should Jay Inslee, for example, not fly while he’s campaigning for president? Surely not.

Should island nations send their delegates to the COPs by boat? Perhaps not be the best use of their resources. But delegates of high emitting nations? Absolutely, they should travel to the COPs emitting the least GHGs as possible. Climate justice from the get-go, I say.

And the political is the personal & visa versa. If flying were a country, its emissions would be sixth largest in the world. And out of the entire population, only 1.5% of us are responsible for the majority of aviation emissions. Flying is climate injustice full stop.

I think considering questions of climate justice in one’s personal practices should be encouraged or even normalized. And who else is going to do that work but people in the climate movement?

As for the argument that calling for the end of unnecessary flying hurts the climate movement because it plays into the hands of the fossil fuel industry…

I can see how the ff industry / denial machine wants to keep everyone’s attention on consumption rather than the managed decline of the ff economy, and I agree it’s tricky to be talking about personal behavior change in a public forum for that reason.
But I think climate twitter is more of a bubble than it seems, and there is a gap between the conversations and debates to be had here and our communication to the general public. (The general public sphere being the second context in which to consider this issue.)
I never try to persuade my friends, my colleagues outside of the climate movement, or the audiences for my talks that they should stop flying. Never.

Not only because it’s a shocking idea for people who have yet to be mobilized, but also because the *only* worthwhile public message IMHO is that everyone needs to take actions that demand and attempt to force *political* and *institutional* change.

But if I am asked I say that I have committed to not flying, and I say why: once I understood that emitting GHGs is fatally dangerous, I felt a kind of categorical imperative to emit as little of them as possible…

…even though the reduction of my own personal emissions of GHGs won’t make any *quantitative* difference overall.

Let me say right away that I have failed in my commitment by flying to Pittsburgh to give a paper beccause I didn’t have time to take the train for family reasons, and…

I flew once w my son and will again until he’s old enough to tolerate the idea of how dangerous climate change might be and why his entire world needs to change. He already knows why we have to cut back (from 8 flights a year to once in 3 years); that’s enough for now.

So it’s complicated, I fuck up all the time, my motherhood conflicts with my activism, we’re all human.

But I am tortured by the question: if we need to bring our emissions down to net zero in 30 years, and the tech for net zero flight is not there yet, everyone is going to need to stop or curtail their flying at least temporarily, no? So why not start now?

And I will acknowledge that sometimes I speak too harshly and admit that I do so because it hurts me, makes me feel most despondent and hopeless, when the people who understand climate change the best are no more willing to give up flying than anyone else.

I know lots of people dislike me for the way I talk about flying. And I see that flying is becoming an increasingly contentious issue.

But as far as wedges go, I think that not grappling w the problem, but dismissing or subtweeting w barely concealed contempt people who express dismay about flying is also pretty divisive.

That said, I realize that nearly everyone I respect and who has devoted their life to this problem disagrees with me. I know that the people who disagree with me want the climate movement to succeed and the world to decarbonize.

I just passionately believe that we are more likely to succeed if we signal the urgency with our actions, unite the word with the deed, and also…

show that life is absolutely beautiful, and meaningful, and interesting, and rewarding, and that people can be successful and have amazing experiences, without needing to spew plumes of carbon dioxide into the sky or, really, ever get on a plane.“

Web Design - The First 100 Years
"Today I hope to persuade you that the same thing that happened to aviation is happening with the Internet. Here we are, fifty years into the computer revolution, at what feels like our moment of greatest progress. The outlines of the future are clear, and oh boy is it futuristic.

But we're running into physical and economic barriers that aren't worth crossing.

We're starting to see that putting everything online has real and troubling social costs.

And the devices we use are becoming 'good enough', to the point where we can focus on making them cheaper, more efficient, and accessible to everyone.

So despite appearances, despite the feeling that things are accelerating and changing faster than ever, I want to make the shocking prediction that the Internet of 2060 is going to look recognizably the same as the Internet today.

Unless we screw it up.

And I want to convince you that this is the best possible news for you as designers, and for us as people."



"So while Moore's Law still technically holds—the number of transistors on a chip keeps increasing—its spirit is broken. Computers don't necessarily get faster with time. In fact, they're getting slower!

This is because we're moving from desktops to laptops, and from laptops to smartphones. Some people are threatening to move us to wristwatches.
In terms of capability, these devices are a step into the past. Compared to their desktop brethren, they have limited memory, weak processors, and barely adequate storage.

And nobody cares, because the advantages of having a portable, lightweight connected device are so great. And for the purposes of taking pictures, making calls, and surfing the internet, they've crossed the threshold of 'good enough'.

What people want from computers now is better displays, better battery life and above all, a better Internet connection.

Something similar happened with storage, where the growth rate was even faster than Moore's Law. I remember the state-of-the-art 1MB hard drive in our computer room in high school. It cost a thousand dollars.
Here's a photo of a multi-megabyte hard drive from the seventies. I like to think that the guy in the picture didn't have to put on the bunny suit, it was just what he liked to wear.

Modern hard drives are a hundred times smaller, with a hundred times the capacity, and they cost a pittance. Seagate recently released an 8TB consumer hard drive.

But again, we've chosen to go backwards by moving to solid state storage, like you find in smartphones and newer laptops. Flash storage sacrifices capacity for speed, efficiency and durability.

Or else we put our data in 'the cloud', which has vast capacity but is orders of magnitude slower.

These are the victories of good enough. This stuff is fast enough.

Intel could probably build a 20 GHz processor, just like Boeing can make a Mach 3 airliner. But they won't. There's a corrollary to Moore's law, that every time you double the number of transistors, your production costs go up. Every two years, Intel has to build a completely new factory and production line for this stuff. And the industry is turning away from super high performance, because most people don't need it.

The hardware is still improving, but it's improving along other dimensions, ones where we are already up against hard physical limits and can't use the trick of miniaturization that won us all that exponential growth.

Battery life, for example. The limits on energy density are much more severe than on processor speed. And it's really hard to make progress. So far our advances have come from making processors more efficient, not from any breakthrough in battery chemistry.

Another limit that doesn't grow exponentially is our ability to move information. There's no point in having an 8 TB hard drive if you're trying to fill it over an AT&T network. Data constraints hit us on multiple levels. There are limits on how fast cores can talk to memory, how fast the computer can talk to its peripherals, and above all how quickly computers can talk to the Internet. We can store incredible amounts of information, but we can't really move it around.

So the world of the near future is one of power constrained devices in a bandwidth-constrained environment. It's very different from the recent past, where hardware performance went up like clockwork, with more storage and faster CPUs every year.

And as designers, you should be jumping up and down with relief, because hard constraints are the midwife to good design. The past couple of decades have left us with what I call an exponential hangover.

Our industry is in complete denial that the exponential sleigh ride is over. Please, we'll do anything! Optical computing, quantum computers, whatever it takes. We'll switch from silicon to whatever you want. Just don't take our toys away.
But all this exponential growth has given us terrible habits. One of them is to discount the present.

When things are doubling, the only sane place to be is at the cutting edge. By definition, exponential growth means the thing that comes next will be equal in importance to everything that came before. So if you're not working on the next big thing, you're nothing.



A further symptom of our exponential hangover is bloat. As soon as a system shows signs of performance, developers will add enough abstraction to make it borderline unusable. Software forever remains at the limits of what people will put up with. Developers and designers together create overweight systems in hopes that the hardware will catch up in time and cover their mistakes.

We complained for years that browsers couldn't do layout and javascript consistently. As soon as that got fixed, we got busy writing libraries that reimplemented the browser within itself, only slower.

It's 2014, and consider one hot blogging site, Medium. On a late-model computer it takes me ten seconds for a Medium page (which is literally a formatted text file) to load and render. This experience was faster in the sixties.

The web is full of these abuses, extravagant animations and so on, forever a step ahead of the hardware, waiting for it to catch up.

This exponential hangover leads to a feeling of exponential despair.

What's the point of pouring real effort into something that is going to disappear or transform in just a few months? The restless sense of excitement we feel that something new may be around the corner also brings with it a hopelessness about whatever we are working on now, and a dread that we are missing out on the next big thing.

The other part of our exponential hangover is how we build our businesses. The cult of growth denies the idea that you can build anything useful or helpful unless you're prepared to bring it to so-called "Internet scale". There's no point in opening a lemonade stand unless you're prepared to take on PepsiCo.

I always thought that things should go the other way. Once you remove the barriers of distance, there's room for all sorts of crazy niche products to find a little market online. People can eke out a living that would not be possible in the physical world. Venture capital has its place, as a useful way to fund long-shot projects, but not everything fits in that mold.

The cult of growth has led us to a sterile, centralized web. And having burned through all the easy ideas within our industry, we're convinced that it's our manifest destiny to start disrupting everyone else.

I think it's time to ask ourselves a very designy question: "What is the web actually for?"
I will argue that there are three competing visions of the web right now. The one we settle on will determine whether the idiosyncratic, fun Internet of today can survive.



Vision 1: CONNECT KNOWLEDGE, PEOPLE, AND CATS.

This is the correct vision.



Vision 2: FIX THE WORLD WITH SOFTWARE

This is the prevailing vision in Silicon Valley.



Vision 3: BECOME AS GODS, IMMORTAL CREATURES OF PURE ENERGY LIVING IN A CRYSTALLINE PARADISE OF OUR OWN CONSTRUCTION

This is the insane vision. I'm a little embarrassed to talk about it, because it's so stupid. But circumstances compel me.



There's a William Gibson quote that Tim O'Reilly likes to repeat: "the future is here, it's just not evenly distributed yet."

O'Reilly takes this to mean that if we surround ourselves with the right people, it can give us a sneak peek at coming attractions.

I like to interpret this quote differently, as a call to action. Rather than waiting passively for technology to change the world, let's see how much we can do with what we already have.

Let's reclaim the web from technologists who tell us that the future they've imagined is inevitable, and that our role in it is as consumers.

The Web belongs to us all, and those of us in this room are going to spend the rest of our lives working there. So we need to make it our home.

We live in a world now where not millions but billions of people work in rice fields, textile factories, where children grow up in appalling poverty. Of those billions, how many are the greatest minds of our time? How many deserve better than they get? What if instead of dreaming about changing the world with tomorrow's technology, we used today's technology and let the world change us? Why do we need to obsess on artificial intelligence, when we're wasting so much natural intelligence?


When I talk about a hundred years of web design, I mean it as a challenge. There's no law that says that things are guaranteed to keep getting better.

The web we have right now is beautiful. It shatters the tyranny of distance. It opens the libraries of the world to you. It gives you a way to bear witness to people half a world away, in your own words. It is full of cats. We built it by accident, yet already we're taking it for granted. We should fight to keep it! "

Christian Groß — SMS to Paper Airplanes
"Purpose, I tried to visualize the text message communication between my girlfriend and myself. Since we are in a long distance relationship and living in two different countries text messages are often the easiest way to communicate. The challenge was to find a medium, which is variable and able to visualize the information of the text messages, but at the same time allows to keep the content private. For me the paper airplane was the perfect image for this scenario, because the text messages as well as travelling by plane are the most common ways for us to cover the distance.

The text messages were filtered and analyzed using PROCESSING. The sender was encoded by the direction of the paper airplane, the length of the message with its size and the amount of positive emotional words with the amounts of folds. Additionally the paper airplanes were divided in two types depending on the length of their text…"

BBC News - Today - A world without planes
"Whatever the advantages of plentiful and convenient air travel, we may curse it for being too easy, too unnoticeable - and thereby for subverting our sincere attempts at changing ourselves through our journeys.

How we would admire planes if they were no longer there to frighten and bore us. We would stroke their steel dolphin-like bodies in museums and honour them as symbols of a daunting technical intelligence and a prodigious wealth.

We would admire them like small boys do, and adults no longer dare, for fear of seeming uncynical and unvigilant towards their crimes against our world."

The Sky’s the Limit for China’s DIY Aviators | Autopia | Wired.com
"China is home to a widespread DIY culture fed by necessity (the mother of all invention) and innovation. These garage builders and innovators are, like their products, often called shanzhai. Literally translated, it means “mountain strongholds,” but it has come to mean nonprofessional or clandestine manufacturers turning out products from the basic to the highly sophisticated. These shanzhai often take familiar products, concepts and marketing memes and remake them with peculiar but innovative twists.
