Trends Identified
Tapped Out
A range of compounding factors risk pushing more megacities towards a “water day zero” that sees the taps run dry. These include population growth, migration, industrialization, climate change, drought, groundwater depletion, weak infrastructure and poor urban planning. Short-termist and polarized politics at both municipal and national levels in many countries further heighten these dangers. The societal shock of running out of water could lead in sharply differing directions depending on the context. It could exacerbate divisions. Conflict might erupt over access to whatever water was still available, or wealthier residents might start to import private supplies. But a water shock could also galvanize communities in the face of a shared existential challenge. Either way, damage would be done. Hygiene would suffer, increasing strains on healthcare systems. And governments blamed for the failure might be tempted to scapegoat weaker communities, such as those in informal dwellings with unofficial connections to the water system. Getting governance and planning right during times of plentiful water would reduce the risk of day zero arising, including public information campaigns and basic maintenance of existing infrastructure, as well as regulations limiting the amount of water that households, businesses and government can use. New water sources could be identified, subject to careful risk assessment. And smart technologies could be deployed to reduce water use and improve water reclamation.

Contested Space
With satellites now central to the smooth functioning of civil and military technologies, the amount of commercial and government activity in space has been increasing. This is a legally ambiguous realm, creating the potential for confusion, accident and even wilful disruption. Space debris is proliferating too—half a million pieces are now moving at the speed of a bullet in low orbit. Even accidental debris collisions could cause significant disruption to internet connectivity and all that relies on it. But at a time of intensifying geopolitical competition, space could also become an arena for active conflict. Even defensive moves to protect critical space assets might trigger a destabilizing arms race. Precision weapons and military earlywarning systems rely on high-orbit satellites—militarizing space might be seen as necessary to deter a crippling attack on them. In the future, as space becomes more affordably accessible, new threats of space-based terrorism could emerge. New rules or updated protocols would provide greater clarity— particularly on the rapid expansion of commercial activity, but also on military activity. Even simple measures could help—such as ensuring transparency on debrisremoval activities to prevent the misinterpretation of intentions. At a time of fraying global cooperation, space might be an area where multilateral advances could be signed up to by all.

Emotional Disruption
As the intertwining of technology with human life deepens, “affective computing”—the use of algorithms that can read human emotions or predict our emotional responses— is likely to become increasingly prevalent. In time, the advent of artificial intelligence (AI) “woebots” and similar tools could transform the delivery of emotional and psychological care—analogous to heart monitors and step counters. But the adverse consequences, either accidental or intentional, of emotionally “intelligent” code could be profound. Consider the various disruptions the digital revolution has already triggered—what would be the affective-computing equivalent of echo chambers or fake news? Of electoral interference or the micro-targeting of advertisements? New possibilities for radicalization would also open up, with machine learning used to identify emotionally receptive individuals and the specific triggers that might push them toward violence. Oppressive governments could deploy affective computing to exert control or whip up angry divisions. To help mitigate these risks, research into potential direct and indirect impacts of these technologies could be encouraged. Mandatory standards could be introduced, placing ethical limits on research and development. Developers could be required to provide individuals with “opt-out” rights. And greater education about potential risks—both for people working in this field and for the general population—would also help.

No Rights Left
Amid a new phase of strong-state politics and deepening domestic polarization, it becomes easier for governments to sacrifice individual protections to collective stability. This already happens widely: lip service is paid to human rights that are breached at home or abroad when it suits states’ interests. What if even lip service goes by the wayside, and human rights are dismissed as anachronisms that weaken the state at a time of growing threats? In authoritarian countries with weak human rights records, the impact of such a tipping point might be one of degree—more rights breached. In some democratic countries, qualitative change would be more likely—a jolt towards an illiberalism in which power-holders determine whose rights get protected, and in which individuals on the losing side of elections risk censorship, detention or violence as “enemies of the people”. Battles are already under way among major powers at the UN over the future of the human rights system. In a multipolar world of divergent fundamental values, building far-reaching consensus in this area may be close to impossible. “Universal” rights are likely to be interpreted locally, and those interpretations then fought over globally. Even superficial changes might be of modest help, such as new language that is less politicized than “human rights”.

Monetary Populism
What if the protectionist wave expanded to engulf the central banks at the heart of the global financial system? Against a backdrop of geo-economic escalation, calls could rise to “take back control” of independent monetary policy and to use it as a weapon in tit-for-tat confrontations between the world’s economies. Prudent and coordinated central bank policies might be attacked by populist politicians as a globalist affront to national democracy. A direct political challenge to the independence of major central banks would unsettle financial markets. Investors might question the solidity of the global financial system’s institutional foundations. As unease deepened, markets might start to tremble, currencies to swing. Uncertainty would spread to the real economy. Polarization would hamper domestic political response, with mounting problems blamed on enemies within and without. Internationally, there might be no actors with the legitimacy to force a coordinated de-escalation. The risk of a populist attack on the world’s financial architecture could be mitigated by deepened efforts to maximize the popular legitimacy of central bank independence. This could be done by bringing the public in—perhaps through formal consultative assemblies— to decisions on independence, accountability and stability. The greater the public understanding of and support for monetary policy mandates and tools, the less vulnerable they will be in times of crisis.

Nanosensors and the Internet of Nanothings
The Internet of Things (IoT), built from inexpensive microsensors and microprocessors paired with tiny power supplies and wireless antennas, is rapidly expanding the online universe from computers and mobile gadgets to ordinary pieces of the physical world: thermostats, cars, door locks, even pet trackers. New IoT devices are announced almost daily, and analysts expected to up to 30 billion of them to be online by 2020. The explosion of connected items, especially those monitored and controlled by artificial intelligence systems, can endow ordinary things with amazing capabilities—a house that unlocks the front door when it recognizes its owner arriving home from work, for example, or an implanted heart monitor that calls the doctor if the organ shows signs of failing. But the real Big Bang in the online universe may lie just ahead. Scientists have started shrinking sensors from millimeters or microns in size to the nanometer scale, small enough to circulate within living bodies and to mix directly into construction materials. This is a crucial first step toward an Internet of Nano Things (IoNT) that could take medicine, energy efficiency, and many other sectors to a whole new dimension. Some of the most advanced nanosensors to date have been crafted by using the tools of synthetic biology to modify single-celled organisms, such as bacteria. The goal here is to fashion simple biocomputers that use DNA and proteins to recognize specific chemical targets, store a few bits of information, and then report their status by changing color or emitting some other easily detectable signal. Synlogic, a start-up in Cambridge, Mass., is working to commercialize computationally enabled strains of probiotic bacteria to treat rare metabolic disorders. Beyond medicine, such cellular nanosensors could find many uses in agriculture and drug manufacturing. Many nanosensors have also been made from non-biological materials, such as carbon nanotubes, that can both sense and signal, acting as wireless nanoantennas. Because they are so small, nanosensors can collect information from millions of different points. External devices can then integrate the data to generate incredibly detailed maps showing the slightest changes in light, vibration, electrical currents, magnetic fields, chemical concentrations and other environmental conditions. The transition from smart nanosensors to the IoNT seems inevitable, but big challenges will have to be met. One technical hurdle is to integrate all the components needed for a self-powered nanodevice to detect a change and transmit a signal to the web. Other obstacles include thorny issues of privacy and safety. Any nanodevices introduced into the body, deliberately or inadvertently, could be toxic or provoke immune reactions. The technology could also enable unwelcome surveillance. Initial applications might be able to avoid the most vexing issues by embedding nanosensors in simpler, less risky organisms such as plants and non-infectious microorganisms used in industrial processing. When it arrives, the IoNT could provide much more detailed, inexpensive, and up-to-date pictures of our cities, homes, factories—even our bodies. Today traffic lights, wearables or surveillance cameras are getting connected to the Internet. Next up: billions of nanosensors harvesting huge amounts of real-time information and beaming it up to the cloud.

Next Generation Batteries
Solar and wind power capacity have been growing at double-digit rates, but the sun sets, and the wind can be capricious. Although every year wind farms get larger and solar cells get more efficient, thanks to advances in materials such as perovskites, these renewable sources of energy still satisfy less than five percent of global electricity demand. In many places, renewables are relegated to niche roles because of the lack of an affordable, reliable technology to store the excess energy that they make when conditions are ideal and to release the power onto the grid as demand picks up. Better batteries could solve this problem, enabling emissions-free renewables to grow even faster—and making it easier to bring reliable electricity to the 1.2 billion people who currently live without it. Within the past few years, new kinds of batteries have been demonstrated that deliver high enough capacity to serve whole factories, towns, or even “mini-grids” connecting isolated rural communities. These batteries are based on sodium, aluminium or zinc. They avoid the heavy metals and caustic chemicals used in older lead-acid battery chemistries. And they are more affordable, more scalable, and safer than the lithium batteries currently used in advanced electronics and electric cars. The newer technology is much better suited to support transmissions systems that rely heavily on solar or wind power. Last October, for example, Fluidic Energy announced an agreement with the government of Indonesia to deploy 35 megawatts of solar panel capacity to 500 remote villages, electrifying the homes of 1.7 million people. The system will use Fluidic’s zinc-air batteries to store up to 250 megawatt-hours of energy in order to provide reliable electricity regardless of the weather. In April, the company inked a similar deal with the government of Madagascar to put 100 remote villages there on a solar-powered mini-grid backed by zinc-air batteries. For people who currently have no access to the grid—no light to work by at night, no Internet to mine for information, no power to do the washing or to irrigate the crops—the combination of renewable generation and grid-scale batteries is utterly transformative, a potent antidote for poverty. But better batteries also hold enormous promise for the rich world as it struggles to meet the formidable challenge of removing most carbon emissions from electricity generation within the next few decades—and doing so at the same time that demand for electricity is growing. The ideal battery is not yet in hand. The new technologies have plenty of room for further improvement. But until recently, advances in grid-scale batteries had been few and far between. So it is heartening to see the pace of progress quickening.

The Blockchain
Blockchain–the technology behind the bitcoin digital currency–is a decentralized public ledger of transactions that no one person or company owns or controls. Instead, every user can access the entire blockchain, and every transfer of funds from one account to another is recorded in a secure and verifiable form by using mathematical techniques borrowed from cryptography. With copies of the blockchain scattered all over the planet, it is considered to be effectively tamper-proof. The challenges that bitcoin poses to law enforcement and international currency controls have been widely discussed. But the blockchain ledger has uses far beyond simple monetary transactions. Like the Internet, the blockchain is an open, global infrastructure upon which other technologies and applications can be built. And like the Internet, it allows people to bypass traditional intermediaries in their dealings with each other, thereby lowering or even eliminating transaction costs. By using the blockchain,individuals can exchange money or purchase insurance securely without a bank account, even across national borders—a feature that could be transformative for the two billion people in the world currently underserved by financial institutions. Blockchain technology lets strangers record simple, enforceable contracts without a lawyer. It makes it possible to sell real estate, event tickets, stocks, and almost any other kind of property or right without a broker. The long-term consequences for professional intermediaries, such as banks, attorneys and brokers, could be profound— and not necessarily in negative ways, because these industries themselves pay huge amounts of transaction fees as a cost of doing business. Analysts at Santander InnoVentures, for example, have estimated that by 2022, blockchain technology could save banks more $20 billion annually in costs. Some 50 big-name banks have announced blockchain initiatives. Investors have poured more than $1 billion in the past year into start-ups formed to exploit the blockchain for a wide range of businesses. Tech giants such as Microsoft, IBM and Google all have blockchain projects underway. Many of these companies are attracted by the potential to use the blockchain to address the privacy and security problems that continue to plague Internet commerce. Because blockchain transactions are recorded using public and private keys—long strings of characters that are unreadable by humans—people can choose to remain anonymous while enabling third parties to verify that they shook, digitally, on an agreement. And not just people: an institution can use the blockchain to store public records and binding promises. Researchers at the University of Cambridge in the U.K., for example, have shown how drug companies could be required to add detailed descriptions of their upcoming clinical drug trials to the blockchain. This would prevent the companies from later moving the goalposts if the trial did not pan out as anticipated, an all-too-common tactic. In London, mayoral candidate George Galloway has proposed putting the city’s annual budget on the blockchain ledger to foster collective auditing by citizens. Perhaps the most encouraging benefit of blockchain technology is the incentive it creates for participants to work honestly where rules apply equally to all. Bitcoin did lead to some famous abuses in trading of contraband, and some nefarious applications of blockchain technology are probably inevitable. The technology doesn’t make theft impossible, just harder. But as an infrastructure that improves society’s public records repository and reinforces representative and participatory legal and governance systems, blockchain technology has the potential to enhance privacy, security and freedom of conveyance of data—which surely ranks up there with life, liberty and the pursuit of happiness.

Two-Dimensional Materials
New materials can change the world. There is a reason we talk about the Bronze Age and the Iron Age. Concrete, stainless steel, and silicon made the modern era possible. Now a new class of materials, each consisting of a single layer of atoms, are emerging, with far-reaching potential. Known as two-dimensional materials, this class has grown within the past few years to include lattice-like layers of carbon (graphene), boron (borophene) and hexagonal boron nitride (aka white graphene), germanium (germanene), silicon (silicene), phosphorous (phosphorene) and tin (stanene). More 2-D materials have been shown theoretically possible but not yet synthesized, such as graphyne from carbon. Each has exciting properties, and the various 2-D substances can be combined like Lego bricks to build still more new materials. This revolution in monolayers started in 2004 when two scientists famously created 2-D graphene using Scotch tape—probably the first time that Nobel-prize-winning science has been done using a tool found in kindergarten classrooms. Graphene is stronger than steel, harder than diamond, lighter than almost anything, transparent, flexible, and an ultrafast electrical conductor. It is also impervious to most substances except water vapor, which flows freely through its molecular mesh. Initially more costly than gold, graphene has tumbled in price thanks to improved production technologies. Hexagonal boron nitride is now also commercially available and set to follow a similar trajectory. Graphene has become cheap enough to incorporate it in water filters, which could make desalination and waste-water treatment far more affordable. As the cost continues to fall, graphene could be added to road paving mixtures or concrete to clean up urban air—on top of its other strengths, the stuff absorbs carbon monoxide and nitrogen oxides from the atmosphere. Other 2-D materials will probably follow the trajectory that graphene has, simultaneously finding use in high-volume applications as the cost falls, and in high-value products like electronics as technologists work out ways to exploit their unique properties. Graphene, for example, has been used to make flexible sensors that can been sewn into garments—or now actually 3-D printed directly into fabrics using new additive manufacturing techniques. When added to polymers, graphene can yield stronger yet lighter airplane wings and bicycle tires. Hexagonal boron nitride has been combined with graphene and boron nitride to improve lithium-ion batteries and supercapacitors. By packing more energy into smaller volumes, the materials can reduce charging times, extend battery life, and lower weight and waste for everything from smart phones to electric vehicles. Whenever new materials enter the environment, toxicity is always a concern. It’s smart to be cautious and to keep an eye out for problems. Ten years of research into the toxicology of graphene has, so far, yielded nothing that raises any concerns over its effects on health or the environment. But studies continue. The invention of 2-D materials has created a new box of powerful tools for technologists. Scientists and engineers are excitedly mixing and matching these ultrathin compounds—each with unique optical, mechanical and electrical properties—to produce tailored materials optimised for a wide range of functions. Steel and silicon, the foundations of 20th-century industrialization, look clumsy and crude by comparison.

Autonomous Vehicles
The rise of the automobile transformed modern society. It changed where we live, what we buy, how we work, and who we call friends. As cars and trucks became commonplace, they created whole classes of jobs and made other professions obsolete. We are now on the cusp of an equally transformative technological shift in transportation: from vehicles driven by humans to vehicles that drive themselves. The long-term impact of autonomous vehicles on society is hard to predict, but also hard to overstate. The only certainty is that wherever this technology becomes ubiquitous, life will be different than it was. Google and other companies have been testing self-driving cars for several years now, with good success. These autos process vast amounts of sensory data from on-board radars, cameras, ultrasonic range-finders, GPS, and stored maps to navigate routes through ever more complex and rapidly changing traffic situations without any human involvement. Consumer use of vehicles with autonomous capabilities, however, is just beginning. Adoption will proceed gradually, through the steady implementation of increasingly intelligent safety and convenience features in otherwise ordinary cars. Some models, for example, already offer hands-off parallel parking, automatic lane-keeping, emergency braking, or even semi-autonomous cruise control. Last October, Tesla Motors made available a software package that enables a limited form of self-driving operation for owners of its vehicles to download. This trend is likely to continue as such technology matures and as legal and regulatory barriers start to fall. A half-dozen states have already authorized autonomous road vehicles, and more have plans to do so. Discussions are well underway among auto insurers and legislators about how to apportion liability and costs when self-driving cars get into crashes, as they inevitably will—although it is widely expected that these cars will prove to be much safer, on average, than driver-operated cars are today. There is plenty of room for improvement on that front. In the United States, crashes and collisions claim more than 30,000 lives and cause some 2.3 million injuries annually. Self-driving systems may have bugs—the software that runs them is complicated—but they are free from the myriad distractions and risk-taking behaviors that are the most common causes of crashes today. In the near term, semi-autonomous safety systems that engage only to prevent accidents, but that otherwise leave the driver in charge, will also likely reduce the human cost of driving significantly. Far more profound transformations will follow once cars and trucks can be trusted to pilot themselves routinely—even with no one inside. Exclusive car ownership could then cease to be the necessity of modern living that it is today for so many people. Shared cars and driverless taxi and delivery services could become the norm. This transition might help the aged and infirm—an increasing fraction of the population—to “age in place” more gracefully. Shared programmable vehicles could reduce the need for local parking structures, reduce congestion by preventing accidents and enabling safe travel at higher speeds and closer following distances, and unlock numerous secondary benefits. Like every technology, autonomous vehicles will involve drawbacks as well. In some distant day, commercial driving may no longer be a sustainable career. Shared vehicles raise some thorny privacy and security concerns. In some regions, increased affordability of car access may greatly exacerbate traffic and pollution problems rather than easing them. But the many benefits of self-driving cars and trucks are so compelling that their widespread adoption is a question of when, not if.
