drone waiters

Singapore is experimenting with drone waiters due to a supposed labor shortage in the service sector. I am all for cool new technologies, but in this particular case I can do without. I actually like the Australian system – you order, get a number or buzzer, and when your food is ready you pick it up at a window. It works just fine. I would save the technology for the ordering and paying part. That would really help with a business lunch, for example, where you are in a hurry and would like to order in advance, then not have to sit around waiting for the check. Combining a sit-down restaurant with online ordering also opens up a lot of possibilities for customizing your order and seeing what other people thought were a restaurant’s best dishes. It should also work well with delivery and mobile food trucks.

2014 Report Card

It’s taken me a while to get out a “year in review” post for 2014, but anyway, here it is. This won’t be a masterpiece of the essay form. I’m just going to ramble on about some interesting trends and themes from the year, along with a few relevant links.

The critical question this blog tries to answer is, is our civilization failing or not? I’ll talk about our human economy, our planetary system, and make some attempt to tie the two together.

Overall Human Health and Wellbeing. First, there are some very happy statistics to report. For example, worldwide child mortality has dropped almost by half just since 1990. What better measure of progress could there be than more happy, healthy childhoods? And it’s not just about increasing wealth – people in developing countries today have much better health outcomes at the same level of wealth compared to developing countries of the past (for example, Indonesia today vs. the United States when it passed the same income level). It’s hard to argue against the idea that economic growth and technological change have obviously eliminated a lot of human suffering. So, I think the important questions are, will these trends continue? Is the system stable? Can the natural environment continue to support this trend indefinitely? There may also be an important question of whether we had the right to exploit the natural environment to get us to the point where we are now, but that is an academic question at this point.

Financial System Instability. Let’s talk about the stability of our human economic system. The U.S. economy may finally seem to be picking up from the aftermath of the severe 2007-8 financial crisis, but it is certainly far below where it would be if that hadn’t happened and the prior growth trend had just continued since then. The rest of the world isn’t doing so well, however – Europe and Japan are looking particularly slow if not in an outright deflationary spiral, at the same time developing countries appear to be slowing down. Some are calling this a “new normal” for the world economy. More scary than that, the industry-written regulations and perverse incentives allowing the excessive risk taking that caused the crisis have not been fully addressed and the whole episode could recur in the short term.

Thoughts on Ecosystem and Economic “Pulsing”. 2007-8 was a textbook financial crisis – although it was caused by novel forms of money and risk taking beyond the direct reach of government regulators and central banks, it was not that different from crises caused by plain old speculation and over-lending back when there were no central banks around. It’s hard to draw a direct link from the financial crisis to ecosystem services, climate change, or natural resource scarcity. However, if we think about natural ecosystems, they are resilient to outside stressors up to a point – say, moderate fluctuations in temperature, hydrology, or pressure from non-native species. However, say a major fluctuation happens such as a major flood or fire that causes serious damage. In the absence of major outside stressors, the system will eventually recover to its original state, but in the presence of major outside stressors, even if they did not cause the flood or fire, it may never bounce back all the way. In the same way, our human economy may appear resilient to the effects of climate change, ocean acidification, soil erosion, and so forth for a long time, but then when something comes out of left field, like a major financial crisis, war, or epidemic, we may not be able to recover to our previous trend. This probably also applies to the effects of technology on employment, as discussed below. In the absence of major shocks coming from outside the system, we’ll see a long, slow slide in employment and possibly a long, slow rise in energy and food prices, with so much noise in the signal that it will be easy for the naysayers to hold sway for long periods of time. But when those major events happen, we may see sudden, painful changes that we have no obvious way of mitigating quickly.

Technological Change: Artificial Intelligence, Robots, Automation, and Employment. After decades of slow but steady progress, these technologies are really coming into their own. Robots are being used to keep miners in line and to drive cars, for example. Manufacturing has become a high-tech industry. As computers and machines get better at performing more and more skilled jobs (book-keeping is one example), there is gradually less demand for the medium-skilled workers who used to do those jobs. High-skilled workers like computer programmers are doing very well, although I presume the automation will gradually creep higher and higher up the chain, so today’s safer jobs will be less safe tomorrow. At the same time these medium-skilled workers in developed countries are getting squeezed out, developing countries are not benefiting like they used to from their large pools of low-skilled workers as manufacturing becomes more and more automated, and can be done cost-effectively closer to consumers in richer countries.

Will our society recognize and solve this employment problem? American corporate society, and its admirers around the world, are unlikely to. Something very similar to this happened with agricultural automation in the early- to mid-20th century, and with globalization in the mid- to late-20th century. As agriculture became more automated, many displaced workers moved from rural areas in the U.S. southeast to urban areas in the U.S. northeast, looking for factory work. Unfortunately, the factory jobs that existed previously were being moved to developing countries with abundant low-wage labor. The pockets of poverty, unemployment, and social problems created by these forces have not been adequately addressed to this day. To the individual worker, it doesn’t much matter whether your job is being taken by a local robot or an overseas human. Unemployment created by technological forces today could resemble what was created by globalization yesterday, only on a much larger scale. We can only hope that the larger scale will drive real political solutions, such as better education and training, sharing of available work, and more widespread ownership of the labor-saving technology.

Of course, one of the earliest and probably the most shameful example of a modern capitalist system generating wealth for an elite few at the expense of workers is the American slavery system of the 18th and 19th centuries. We just can’t trust amoral, self-interested private enterprise to maximize welfare in the absence of a strong moral compass coming from the larger society. Let’s stop pretending otherwise.

Another example of extreme corporate immorality: Public apathy over climate change in the U.S. may have been manufactured by a cynical, immoral corporate disinformation campaign over climate change taken right out of the tobacco companies’ playbook.

The Gospel of Shareholder Value. There is an important debate over whether people who run corporations have any ethical responsibility to anything other than profit seeking. Well duh, everyone on Earth has an ethical responsibility. Case closed, as far as I’m concerned. There is even evidence that the ideology of profit maximization is a drag on innovation. Except billions of people out there who have worshiped at business schools would disagree with me. And I don’t want to offend anyone’s religion. Noam Chomsky had a quote that I particularly loved, so I am going to repeat it here:

In market systems, you don’t take account of what economists call externalities. So say you sell me a car. In a market system, we’re supposed to look after our own interests, so I make the best deal I can for me; you make the best deal you can for you. We do not take into account the effect on him. That’s not part of a market transaction. Well, there is an effect on him: there’s another car on the road; there’s a greater possibility of accidents; there’s more pollution; there’s more traffic jams. For him individually, it might be a slight increase, but this is extended over the whole population. Now, when you get to other kinds of transactions, the externalities get much larger. So take the financial crisis. One of the reasons for it is that — there are several, but one is — say if Goldman Sachs makes a risky transaction, they — if they’re paying attention — cover their own potential losses. They do not take into account what’s called systemic risk, that is, the possibility that the whole system will crash if one of their risky transactions goes bad. That just about happened with AIG, the huge insurance company. They were involved in risky transactions which they couldn’t cover. The whole system was really going to collapse, but of course state power intervened to rescue them. The task of the state is to rescue the rich and the powerful and to protect them, and if that violates market principles, okay, we don’t care about market principles. The market principles are essentially for the poor. But systemic risk is an externality that’s not considered, which would take down the system repeatedly, if you didn’t have state power intervening. Well there’s another one, that’s even bigger — that’s destruction of the environment. Destruction of the environment is an externality: in market interactions, you don’t pay attention to it. So take tar sands. If you’re a major energy corporation and you can make profit out of exploiting tar sands, you simply do not take into account the fact that your grandchildren may not have a possibility of survival — that’s an externality. And in the moral calculus of capitalism, greater profits in the next quarter outweigh the fate of your grandchildren — and of course it’s not your grandchildren, but everyone’s.

Our Ecological Footprint. WWF issued an updated Living Planet Report in 2014 suggesting that our annual consumption of natural resources (including the obvious ones like energy and water extraction, straightforward ones like the ability to grow food, but also the less obvious ones like ability of the oceans and atmosphere to absorb our waste products) is continuing to exceed what the Earth can handle each year by at least 50%. We’re like spoiled trust fund babies – we have such incredible resources at our disposable, we never learn to live within our means and one day the resources run out, even if that takes a long time. As we recover from the financial crisis, we have a chance to do things differently, but the connections are not being made to the right kinds of investments in infrastructure, skills, and protection of natural capital that would set the stage for long-term sustainable growth in the future.

Other Big Stories from 2014:

  • World War I. 100 years ago, World War I was in full swing. Remember The Guns of August? Well, that was August 1914 they were talking about. Let’s hope we’re not about to blunder into another conflict. But (and I’m cheating a little here because I read this in 2015), the World Economic Forum named “interstate conflict” as both high probability and high consequence in its global risk report.
  • Ebola. Obviously, Ebola was a very bad thing that happened to a whole lot of people. To those of us lucky enough that we weren’t directly in its path, it is a chance to selfishly reflect whether Ebola or something even worse could be coming down the pike. Let’s hope not.
  • Severe Drought and Water Depletion in the Western U.S.: California has been in the midst of a historic drought, although they got some rain recently. Some are describing this as the new normal. Besides rainfall, glaciers, snowpack, and groundwater all seem to be disappearing in some important food-growing areas.
  • Solar grid parity is here! At least some places, some times…

Conclusion. Yes, I think we are on a path to collapse if nothing changes. And I don’t see things changing enough, or fast enough. There are glimmers of hope though. Lest you think I offer only negatives and no solutions, here are two solutions I harp on constantly throughout the blog:

  • Green infrastructure. This is how we fix the hydrologic cycle, close the loop on nutrients, begin to cleanse the atmosphere, protect wild creatures and genetic diversity, and create a society of people with some sense of connection to and stewardship over nature. Don’t act like it’s such a big mystery. It’s known technology. There has been plenty written about trees, design of wildlife corridors and connectivity, for examples. There is simply no excuse for cities to do such a crappy job with these things.
  • Muscle-Powered Transportation. Cars are clearly the root of all evil, the spawn of Mordor, as I pointed out several times (sorry, I just sat through 6+ hours of Hobbit movies). Unless you are perhaps that rare hobbit who can own a car without your morals being completed corrupted by its evil powers. But for the rest of us, I explained several times why getting rid of cars would be good. Here is just one example:

One of the most important things we can do to build a sustainable, resilient society is to design communities where most people can make most of their daily trips under their own power – on foot or by bicycle. It eliminates a huge amount of carbon emissions. It opens up enormous quantities of land to new possibilities other than roads and parking, which right now take up half or more of the land in urban areas. It reduces air pollution and increases physical activity, two things that are taking years off our lives. It eliminates crashes between vehicles, and crashes between vehicles and human bodies, which are serial killers of one million people worldwide every year, especially serial killers of children. It eliminates enormous amounts of dead, wasted time, because commuting is now a physically and mentally beneficial use of time. There is also a subtle effect, I believe, of creating more social interaction and trust and empathy between people just because they come into more contact, and creating a more vibrant, creative and innovative economy that might have a shot at solving our civilization’s more pressing problems.

January 2015 in Review

I’m dropping my “Hope for the Future Index” this year. If anyone out there is particularly attached to it, you can let me know.

Negative trends and predictions:

  • According to Mikhail Gorbachev, “Today’s key global problems – terrorism and extremism, poverty and inequality, climate change, migration, and epidemics – are worsening daily.”
  • Exxon predicts the rate of greenhouse gas emissions will stop growing…by 2030…at a level that will still cause atmospheric concentrations to continue rising. They try to present this as good news, but it is clearly a pathway to collapse if you think about it just a little bit.
  • Johan Rockstrom and company have updated their 2009 planetary boundaries work. The news is not getting any better. 4 of the 9 boundaries are not in the “safe operating space”: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).
  • By several measures, 2014 was the hottest year on record.
  • The Doomsday Clock has moved from 5 minutes to 3 minutes from midnight due to “climate change and efforts to modernize nuclear weapons stockpiles”.

Positive trends and predictions:

  • Taxi medallions have been called the “best investment in America”, but now ride-sharing services may destroy them. I put this in the positive column because I think the new services are better and this is a good example of creative destruction.
  • Remote controlled, robot-assisted surgery is here.
  • The ongoing tumble in oil prices was of course a big story throughout the month. We won’t really be able to say until we look back years from now whether this was just a short-term fluctuation or the reversal of the decades-long trend toward higher energy prices. My guess is the former.
  • It is starting to seem politically possible for the U.S. to strengthen regulation of risk-taking by huge financial firms.
  • Robots can learn to perform physical tasks by watching videos.
  • Howard T. Odum was a genius who invented a “system language” that, if widely understood and applied, might give humanity the tools to solve its problems. Unfortunately, so far it is not widely understood or applied.
  • There may be a realistic chance for a de-escalation of the Middle East nuclear arms race.

robot library of the future

This is an interesting article by Philadelphia Inquirer critic Inga Saffron about the new library at Temple University, which is going to use robots to retrieve books. This allows the books to be stored in a very small space, and the rest of the building to be used for technology, meeting rooms, collaborative work spaces, and social spaces. This is based on warehouse technology used by Amazon and others, and has already been implemented at the North Carolina State University library.

Joe Lucia, Temple’s dean of libraries, believes these buildings are the most inclusive spaces at a university and serve as an “academic Switzerland.” An engineering student may never wander into the humanities building, he explained, but all students need to consult a library’s holdings. The library’s location on the new central quad will cement its place as Temple’s community center. Besides the glass reading room, the building will be packed with study rooms, seminar rooms, digital work spaces, as well as a ground floor café-and-study area that will be open 24 hours.

The wealth of work spaces is made possible by the automated book-retrieval system. The new library will be about 200,000 square feet, roughly the same as the existing Paley Library, built in 1966 by Nolen-Swinburne. (It will probably be retrofitted for classrooms.) But because the automated system allows the new library to store books in tightly packed trays, storage will take up just 10,000 square feet. The ratio is almost the reverse at Paley, which has open stacks. Because the books will be protected in their own concrete room, the new library can have many more windows. It is sad that the one place where windows are scarce is on the side facing Liacouras walk. Long blank walls could be off-putting on such a pedestrian stretch, and Temple officials say they are exploring some design changes.

One of the good things about the automatic book-retrieving system is that it’s already been tested at Snohetta projects such as the Hunt Library at North Carolina State University in Raleigh. The system delivers the books within five minutes, and it’s become such an attraction that students are known to take selfies with the robot.

This also makes me think about the future of urban retail. Who will need big box stores with shelves packed full of duplicate items? Instead you can have showrooms with just one of each item, or even holograms, for people who want an up-close look at an item they have already seen on the internet at home. The actual items to be purchased can be stored very compactly in the back, basement, or second floor of the store, and retrieved in minutes by a robot. For that matter, why would you want to carry a bulky item home if it can be delivered to your door within a few hours. In that case, it doesn’t matter if the warehouse is down the street, on the edge of town, or out by the airport or rail station or factory that actually makes the items. Each retailer doesn’t need to operate its own warehouse and delivery system. If 3D-printing technology really comes into its own, this system would get even more interesting.

robots learning to use tools

This article from KurzweilAI is about robots learning to use tools by watching videos on the internet.

This paper presents a system that learns manipulation
action plans by processing unconstrained videos from
the World Wide Web. Its goal is to robustly generate the sequence
of atomic actions of seen longer actions in video in
order to acquire knowledge for robots. The lower level of the
system consists of two convolutional neural network (CNN)
based recognition modules, one for classifying the hand grasp
type and the other for object recognition. The higher level
is a probabilistic manipulation action grammar based parsing
module that aims at generating visual sentences for robot
manipulation. Experiments conducted on a publicly available
unconstrained video dataset show that the system is able
to learn manipulation actions by “watching” unconstrained
videos with high accuracy

Robots, pay attention – I just Googled videos on “how to clean a bathroom” and got over 33 million results, so get to work!

December 2014 in Review

At the end of November, my Hope for the Future Index stood at -2.  I’ll give December posts a score from -3 to +3 based on how negative or positive they are.

Negative trends and predictions (-12):

  • When you consider roads, streets, and parking, cars take up more space in cities than housing. (-2)
  • The latest on productivity and economic growth: Paul Krugman says there is risk of deflationary spirals in many countries, and the U.S. economy is nothing to right home about. (-1)
  • There are a few legitimate scientists out there warning of sudden, catastrophic climate change in the near future. (-1)
  • Automation (meaning robots and AI) is estimated to threaten 47% of all U.S. jobs. One area of active research into automation: weaponry. Only one negative point because there are also some positive implications. (-1)
  • Margaret Atwood’s Year of the Flood is a depressing but entertaining reminder that bio-apocalypse is possible. (-2)
  • Before the recent rains, the drought in California was estimated to be a once-in-1200-years event. Major droughts in major food growing regions are not good news, especially with depletion of groundwater, and loss of snowpack and glaciers also in the news. (-2)
  • William Lazonick argues provides evidence that the rise in the gospel of shareholder value correlated with the growth slowdown that started in the 1970s – his explanation is that before that, retained earnings were a cornerstone of R&D and innovation in the economy. Loss of a point because it’s good to hear a dissenting voice, but the economy is still run by disciples of the profits for now. (-1)
  • Elizabeth Warren and Bernie Sanders are warning that the U.S. financial system may still be dangerously unstable. (-2)

Positive trends and predictions (+6):

  • There are some new ideas out there for teaching computer programming, even to young children: Loco Robo, Scratch, and for-profit “programming boot camps”. (+1)
  • You can now get genetically customized probiotics for your vagina. (+1)
  • There are plenty of ideas and models out there for safe, walkable streets, some as simple as narrower lanes. But as I point out, the Dutch and Danish designs are pretty much perfect and should just be adopted everywhere. (+1)
  • I linked to a new video depicting Michael Graves’s idea for “linear cities“. These could be very sustainable ecological if they meant the rest of the landscape is left in a mostly natural condition. I am not as sure about social sustainability – done wrong, they could be like living in a mall or subway station. This was one of my all-time more popular posts. (+1)
  • There are new algorithms out there for aggregating and synthesizing large amounts of scientific literature. Maybe this can increase the returns to R&D and help boost innovation. (+1)
  • There will be several international conferences in 2015 with potential to make real progress on financial stability and sustainability. The phrase “deep decarbonization” has been uttered. (+1)
  • Some evidence suggests that the oceans have absorbed a lot of global warming over the past decade or so, preventing the more extreme range of land surface warming that had been predicted. This is a good short- to medium-term trend, but it may not continue in the long term. (+0)

change during December 2014: -12 + 6 = -6

Hope for the Future Index (end of December 2014): -2 -6 = -8

robots robots robots!

Yes, there’s a robot bartender now.

No word on whether this is a bar where everybody knows your name. I suspect not. Here’s a much longer academic study on which occupations are likely to be most affected by computerization/automation in coming decades.

According to our estimates around 47 percent of total US employment is in the high risk category. We refer to these as jobs at risk – i.e. jobs we expect could be automated relatively soon, perhaps over the next decade or two. Our model predicts that most workers in transportation and logistics occupations, together with the bulk of office and administrative support workers, and labour in production occupations, are at risk. These findings are consistent with recent technological developments documented in the literature. More surprisingly, we find that a substantial share of employment in service occupations,where most US job growth has occurred over the past decades (Autor and Dorn, 2013), are highly susceptible to computerisation. Additional support for this finding is provided by the recent growth in the market for service robots (MGI, 2013) and the gradually diminishment of the comparative advantage of human labour in tasks involving mobility and dexterity (Robotics-VO, 2013).

The paper has a detailed appendix where you can look up your specific occupation if you are so inclined. In also has a detailed lesson on the history of technology and labor markets, if you are inclined to read that.

Finally, the Pentagon is also worried about falling behind the curve on automation:

Hagel and DOD officials have been discussing the so-called third offset strategy for months without giving up any specifics as to how they intend to achieve offset innovation. In his speech, Hagel provided a small glimpse into the fields that will attract special Defense Department attention as part of the strategy: “robotics, autonomous systems, miniaturization, big data, and advanced manufacturing, including 3-D printing.”

nanotech “pill”

According to Wired, Google X is working on nanotechnology that can swim around in your blood and tell you what it finds:

“Because the core of these particles is magnetic, you can call them somewhere,” Conrad said, indicating that you could use a wearable device to gather them in the superficial veins on the inside of your wrist. “These little particles go out and mingle with the people, we call them back to one place, and we ask them: ‘Hey, what did you see? Did you find cancer? Did you see something that looks like a fragile plaque for a heart attack? Did you see too much sodium?”
