#435174 Revolt on the Horizon? How Young People ...

As digital technologies facilitate the growth of both new and incumbent organizations, we have started to see the darker sides of the digital economy unravel. In recent years, many unethical business practices have been exposed, including the capture and use of consumers’ data, anticompetitive activities, and covert social experiments.

But what do young people who grew up with the internet think about this development? Our research with 400 digital natives—19- to 24-year-olds—shows that this generation, dubbed “GenTech,” may be the one to turn the digital revolution on its head. Our findings point to a frustration and disillusionment with the way organizations have accumulated real-time information about consumers without their knowledge and often without their explicit consent.

Many from GenTech now understand that their online lives are of commercial value to an array of organizations that use this insight for the targeting and personalization of products, services, and experiences.

This era of accumulation and commercialization of user data through real-time monitoring has been coined “surveillance capitalism” and signifies a new economic system.

Artificial Intelligence
A central pillar of the modern digital economy is our interaction with artificial intelligence (AI) and machine learning algorithms. We found that 47 percent of GenTech do not want AI technology to monitor their lifestyle, purchases, and financial situation in order to recommend them particular things to buy.

In fact, only 29 percent see this as a positive intervention. Instead, they wish to maintain a sense of autonomy in their decision making and have the opportunity to freely explore new products, services, and experiences.

As individuals living in the digital age, we constantly negotiate with technology to let go of or retain control. This pendulum-like effect reflects the ongoing battle between humans and technology.

My Life, My Data?
Our research also reveals that 54 percent of GenTech are very concerned about the access organizations have to their data, while only 19 percent were not worried. Despite the EU General Data Protection Regulation being introduced in May 2018, this is still a major concern, grounded in a belief that too much of their data is in the possession of a small group of global companies, including Google, Amazon, and Facebook. Some 70 percent felt this way.

In recent weeks, both Facebook and Google have vowed to make privacy a top priority in the way they interact with users. Both companies have faced public outcry for their lack of openness and transparency when it comes to how they collect and store user data. It wasn’t long ago that a hidden microphone was found in one of Google’s home alarm products.

Google now plans to offer auto-deletion of users’ location history data, browsing, and app activity as well as extend its “incognito mode” to Google Maps and search. This will enable users to turn off tracking.

At Facebook, CEO Mark Zuckerberg is keen to reposition the platform as a “privacy focused communications platform” built on principles such as private interactions, encryption, safety, interoperability (communications across Facebook-owned apps and platforms), and secure data storage. This will be a tough turnaround for the company that is fundamentally dependent on turning user data into opportunities for highly individualized advertising.

Privacy and transparency are critically important themes for organizations today, both for those that have “grown up” online as well as the incumbents. While GenTech want organizations to be more transparent and responsible, 64 percent also believe that they cannot do much to keep their data private. Being tracked and monitored online by organizations is seen as part and parcel of being a digital consumer.

Despite these views, there is a growing revolt simmering under the surface. GenTech want to take ownership of their own data. They see this as a valuable commodity, which they should be given the opportunity to trade with organizations. Some 50 percent would willingly share their data with companies if they got something in return, for example a financial incentive.

Rewiring the Power Shift
GenTech are looking to enter into a transactional relationship with organizations. This reflects a significant change in attitudes from perceiving the free access to digital platforms as the “product” in itself (in exchange for user data), to now wishing to use that data to trade for explicit benefits.

This has created an opportunity for companies that seek to empower consumers and give them back control of their data. Several companies now offer consumers the opportunity to sell the data they are comfortable sharing or take part in research that they get paid for. More and more companies are joining this space, including People.io, Killi, and Ocean Protocol.

Sir Tim Berners Lee, the creator of the world wide web, has also been working on a way to shift the power from organizations and institutions back to citizens and consumers. The platform, Solid, offers users the opportunity to be in charge of where they store their data and who can access it. It is a form of re-decentralization.

The Solid POD (Personal Online Data storage) is a secure place on a hosted server or the individual’s own server. Users can grant apps access to their POD as a person’s data is stored centrally and not by an app developer or on an organization’s server. We see this as potentially being a way to let people take back control from technology and other companies.

GenTech have woken up to a reality where a life lived “plugged in” has significant consequences for their individual privacy and are starting to push back, questioning those organizations that have shown limited concern and continue to exercise exploitative practices.

It’s no wonder that we see these signs of revolt. GenTech is the generation with the most to lose. They face a life ahead intertwined with digital technology as part of their personal and private lives. With continued pressure on organizations to become more transparent, the time is now for young people to make their move.

#435152 The Futuristic Tech Disrupting Real ...

In the wake of the housing market collapse of 2008, one entrepreneur decided to dive right into the failing real estate industry. But this time, he didn’t buy any real estate to begin with. Instead, Glenn Sanford decided to launch the first-ever cloud-based real estate brokerage, eXp Realty.

Contracting virtual platform VirBELA to build out the company’s mega-campus in VR, eXp Realty demonstrates the power of a dematerialized workspace, throwing out hefty overhead costs and fundamentally redefining what ‘real estate’ really means. Ten years later, eXp Realty has an army of 14,000 agents across all 50 US states, 3 Canadian provinces, and 400 MLS market areas… all without a single physical office.

But VR is just one of many exponential technologies converging to revolutionize real estate and construction. As floating cities and driverless cars spread out your living options, AI and VR are together cutting out the middleman.

Already, the global construction industry is projected to surpass $12.9 trillion in 2022, and the total value of the US housing market alone grew to $33.3 trillion last year. Both vital for our daily lives, these industries will continue to explode in value, posing countless possibilities for disruption.

In this blog, I’ll be discussing the following trends:

New prime real estate locations;
Disintermediation of the real estate broker and search;
Materials science and 3D printing in construction.

Let’s dive in!

Location Location Location
Until today, location has been the name of the game when it comes to hunting down the best real estate. But constraints on land often drive up costs while limiting options, and urbanization is only exacerbating the problem.

Beyond the world of virtual real estate, two primary mechanisms are driving the creation of new locations.

(1) Floating Cities

Offshore habitation hubs, floating cities have long been conceived as a solution to rising sea levels, skyrocketing urban populations, and threatened ecosystems. In success, they will soon unlock an abundance of prime real estate, whether for scenic living, commerce, education, or recreation.

One pioneering model is that of Oceanix City, designed by Danish architect Bjarke Ingels and a host of other domain experts. Intended to adapt organically over time, Oceanix would consist of a galaxy of mass-produced, hexagonal floating modules, built as satellite “cities” off coastal urban centers and sustained by renewable energies.

While individual 4.5-acre platforms would each sustain 300 people, these hexagonal modules are designed to link into 75-acre tessellations sustaining up to 10,000 residents. Each anchored to the ocean floor using biorock, Oceanix cities are slated to be closed-loop systems, as external resources are continuously supplied by automated drone networks.

Electric boats or flying cars might zoom you to work, city-embedded water capture technologies would provide your water, and while vertical and outdoor farming supply your family meal, share economies would dominate goods provision.

Joined by countless government officials whose islands risk submersion at the hands of sea level rise, the UN is now getting on board. And just this year, seasteading is exiting the realm of science fiction and testing practical waters.

As French Polynesia seeks out robust solutions to sea level rise, their government has now joined forces with the San Francisco-based Seasteading Institute. With a newly designated special economic zone and 100 acres of beachfront, this joint Floating Island Project could even see up to a dozen inhabitable structures by 2020. And what better to fund the $60 million project than the team’s upcoming ICO?

But aside from creating new locations, autonomous vehicles (AVs) and flying cars are turning previously low-demand land into the prime real estate of tomorrow.

(2) Autonomous Electric Vehicles and Flying Cars

Today, the value of a location is a function of its proximity to your workplace, your city’s central business district, the best schools, or your closest friends.

But what happens when driverless cars desensitize you to distance, or Hyperloop and flying cars decimate your commute time? Historically, every time new transit methods have hit the mainstream, tolerance for distance has opened up right alongside them, further catalyzing city spread.

And just as Hyperloop and the Boring Company aim to make your commute immaterial, autonomous vehicle (AV) ridesharing services will spread out cities in two ways: (1) by drastically reducing parking spaces needed (vertical parking decks = more prime real estate); and (2) by untethering you from the steering wheel. Want an extra two hours of sleep on the way to work? Schedule a sleeper AV and nap on your route to the office. Need a car-turned-mobile-office? No problem.

Meanwhile, aerial taxis (i.e. flying cars) will allow you to escape ground congestion entirely, delivering you from bedroom to boardroom at decimated time scales.

Already working with regulators, Uber Elevate has staked ambitious plans for its UberAIR airborne taxi project. By 2023, Uber anticipates rolling out flying drones in its two first pilot cities, Los Angeles and Dallas. Flying between rooftop skyports, drones would carry passengers at a height of 1,000 to 2,000 feet at speeds between 100 to 200 mph. And while costs per ride are anticipated to resemble those of an Uber Black based on mileage, prices are projected to soon drop to those of an UberX.

But the true economic feat boils down to this: if I were to commute 50 to 100 kilometers, I could get two or three times the house for the same price. (Not to mention the extra living space offered up by my now-unneeded garage.)

All of a sudden, virtual reality, broadband, AVs, or high-speed vehicles are going to change where we live and where we work. So rather than living in a crowded, dense urban core for access to jobs and entertainment, our future of personalized, autonomous, low-cost transport opens the luxury of rural areas to all without compromising the benefits of a short commute.

Once these drivers multiply your real estate options, how will you select your next home?

Disintermediation: Say Bye to Your Broker
In a future of continuous and personalized preference-tracking, why hire a human agent who knows less about your needs and desires than a personal AI?

Just as disintermediation is cutting out bankers and insurance agents, so too is it closing in on real estate brokers. Over the next decade, as AI becomes your agent, VR will serve as your medium.

To paint a more vivid picture of how this will look, over 98 percent of your home search will be conducted from the comfort of your couch through next-generation VR headgear.

Once you’ve verbalized your primary desires for home location, finishings, size, etc. to your personal AI, it will offer you top picks, tour-able 24/7, with optional assistance by a virtual guide and constantly updated data. As a seller, this means potential buyers from two miles, or two continents, away.

Throughout each immersive VR tour, advanced eye-tracking software and a permissioned machine learning algorithm follow your gaze, further learn your likes and dislikes, and intelligently recommend other homes or commercial residences to visit.

Curious as to what the living room might look like with a fresh coat of blue paint and a white carpet? No problem! VR programs will be able to modify rendered environments instantly, changing countless variables, from furniture materials to even the sun’s orientation. Keen to input your own furniture into a VR-rendered home? Advanced AIs could one day compile all your existing furniture, electronics, clothing, decorations, and even books, virtually organizing them across any accommodating new space.

As 3D scanning technologies make extraordinary headway, VR renditions will only grow cheaper and higher resolution. One company called Immersive Media (disclosure: I’m an investor and advisor) has a platform for 360-degree video capture and distribution, and is already exploring real estate 360-degree video.

Smaller firms like Studio 216, Vieweet, Arch Virtual, ArX Solutions, and Rubicon Media can similarly capture and render models of various properties for clients and investors to view and explore. In essence, VR real estate platforms will allow you to explore any home for sale, do the remodel, and determine if it truly is the house of your dreams.

Once you’re ready to make a bid, your AI will even help estimate a bid, process and submit your offer. Real estate companies like Zillow, Trulia, Move, Redfin, ZipRealty (acquired by Realogy in 2014) and many others have already invested millions in machine learning applications to make search, valuation, consulting, and property management easier, faster, and much more accurate.

But what happens if the home you desire most means starting from scratch with new construction?

New Methods and Materials for Construction
For thousands of years, we’ve been constrained by the construction materials of nature. We built bricks from naturally abundant clay and shale, used tree limbs as our rooftops and beams, and mastered incredible structures in ancient Rome with the use of cement.

But construction is now on the cusp of a materials science revolution. Today, I’d like to focus on three key materials:

Upcycled Materials

Imagine if you could turn the world’s greatest waste products into their most essential building blocks. Thanks to UCLA researchers at CO2NCRETE, we can already do this with carbon emissions.

Today, concrete produces about five percent of all greenhouse gas (GHG) emissions. But what if concrete could instead conserve greenhouse emissions? CO2NCRETE engineers capture carbon from smokestacks and combine it with lime to create a new type of cement. The lab’s 3D printers then shape the upcycled concrete to build entirely new structures. Once conquered at scale, upcycled concrete will turn a former polluter into a future conserver.

Or what if we wanted to print new residences from local soil at hand? Marking an extraordinary convergence between robotics and 3D printing, the Institute of Advanced Architecture of Catalonia (IAAC) is already working on a solution.

In a major feat for low-cost construction in remote zones, IAAC has found a way to convert almost any soil into a building material with three times the tensile strength of industrial clay. Offering myriad benefits, including natural insulation, low GHG emissions, fire protection, air circulation, and thermal mediation, IAAC’s new 3D printed native soil can build houses on-site for as little as $1,000.

Nanomaterials

Nano- and micro-materials are ushering in a new era of smart, super-strong, and self-charging buildings. While carbon nanotubes dramatically increase the strength-to-weight ratio of skyscrapers, revolutionizing their structural flexibility, nanomaterials don’t stop here.

Several research teams are pioneering silicon nanoparticles to capture everyday light flowing through our windows. Little solar cells at the edges of windows then harvest this energy for ready use. Researchers at the US National Renewable Energy Lab have developed similar smart windows. Turning into solar panels when bathed in sunlight, these thermochromic windows will power our buildings, changing color as they do.

Self-Healing Infrastructure

The American Society of Civil Engineers estimates that the US needs to spend roughly $4.5 trillion to fix nationwide roads, bridges, dams, and common infrastructure by 2025. But what if infrastructure could fix itself?

Enter self-healing concrete. Engineers at Delft University have developed bio-concrete that can repair its own cracks. As head researcher Henk Jonkers explains, “What makes this limestone-producing bacteria so special is that they are able to survive in concrete for more than 200 years and come into play when the concrete is damaged. […] If cracks appear as a result of pressure on the concrete, the concrete will heal these cracks itself.”

But bio-concrete is only the beginning of self-healing technologies. As futurist architecture firms start printing plastic and carbon-fiber houses like the stunner seen below (using Branch Technologies’ 3D printing technology), engineers have begun tackling self-healing plastic.

And in a bid to go smart, burgeoning construction projects have started embedding sensors for preemptive detection. Beyond materials and sensors, however, construction methods are fast colliding into robotics and 3D printing.

While some startups and research institutes have leveraged robot swarm construction (namely, Harvard’s robotic termite-like swarm of programmed constructors), others have taken to large-scale autonomous robots.

One such example involves Fastbrick Robotics. After multiple iterations, the company’s Hadrian X end-to-end bricklaying robot can now autonomously build a fully livable, 180-square meter home in under 3 days. Using a laser-guided robotic attachment, the all-in-one brick-loaded truck simply drives to a construction site and directs blocks through its robotic arm in accordance with a 3D model.

Meeting verified building standards, Hadrian and similar solutions hold massive promise in the long term, deployable across post-conflict refugee sites and regions recovering from natural catastrophes.

Imagine the implications. Eliminating human safety concerns and unlocking any environment, autonomous builder robots could collaboratively build massive structures in space or deep underwater habitats.

Final Thoughts
Where, how, and what we live in form a vital pillar of our everyday lives. The concept of “home” is unlikely to disappear anytime soon. At the same time, real estate and construction are two of the biggest playgrounds for technological convergence, each on the verge of revolutionary disruption.

As underlying shifts in transportation, land reclamation, and the definition of “space” (real vs. virtual) take hold, the real estate market is about to explode in value, spreading out urban centers on unprecedented scales and unlocking vast new prime “property.”

Meanwhile, converging advancements in AI and VR are fundamentally disrupting the way we design, build, and explore new residences. Just as mirror worlds create immersive, virtual real estate economies, VR tours and AI agents are absorbing both sides of the coin to entirely obliterate the middleman.

And as materials science breakthroughs meet new modes of construction, the only limits to tomorrow’s structures are those of our own imagination.

#435106 Could Artificial Photosynthesis Help ...

Plants are the planet’s lungs, but they’re struggling to keep up due to rising CO2 emissions and deforestation. Engineers are giving them a helping hand, though, by augmenting their capacity with new technology and creating artificial substitutes to help them clean up our atmosphere.

Imperial College London, one of the UK’s top engineering schools, recently announced that it was teaming up with startup Arborea to build the company’s first outdoor pilot of its BioSolar Leaf cultivation system at the university’s White City campus in West London.

Arborea is developing large solar panel-like structures that house microscopic plants and can be installed on buildings or open land. The plants absorb light and carbon dioxide as they photosynthesize, removing greenhouse gases from the air and producing organic material, which can be processed to extract valuable food additives like omega-3 fatty acids.

The idea of growing algae to produce useful materials isn’t new, but Arborea’s pitch seems to be flexibility and affordability. The more conventional approach is to grow algae in open ponds, which are less efficient and open to contamination, or in photo-bioreactors, which typically require CO2 to be piped in rather than getting it from the air and can be expensive to run.

There’s little detail on how the technology deals with issues like nutrient supply and harvesting or how efficient it is. The company claims it can remove carbon dioxide as fast as 100 trees using the surface area of just a single tree, but there’s no published research to back that up, and it’s hard to compare the surface area of flat panels to that of a complex object like a tree. If you flattened out every inch of a tree’s surface it would cover a surprisingly large area.

Nonetheless, the ability to install these panels directly on buildings could present a promising way to soak up the huge amount of CO2 produced in our cities by transport and industry. And Arborea isn’t the only one trying to give plants a helping hand.

For decades researchers have been working on ways to use light-activated catalysts to split water into oxygen and hydrogen fuel, and more recently there have been efforts to fuse this with additional processes to combine the hydrogen with carbon from CO2 to produce all kinds of useful products.

Most notably, in 2016 Harvard researchers showed that water-splitting catalysts could be augmented with bacteria that combines the resulting hydrogen with CO2 to create oxygen and biomass, fuel, or other useful products. The approach was more efficient than plants at turning CO2 to fuel and was built using cheap materials, but turning it into a commercially viable technology will take time.

Not everyone is looking to mimic or borrow from biology in their efforts to suck CO2 out of the atmosphere. There’s been a recent glut of investment in startups working on direct-air capture (DAC) technology, which had previously been written off for using too much power and space to be practical. The looming climate change crisis appears to be rewriting some of those assumptions, though.

Most approaches aim to use the concentrated CO2 to produce synthetic fuels or other useful products, creating a revenue stream that could help improve their commercial viability. But we look increasingly likely to surpass the safe greenhouse gas limits, so attention is instead turning to carbon-negative technologies.

That means capturing CO2 from the air and then putting it into long-term storage. One way could be to grow lots of biomass and then bury it, mimicking the process that created fossil fuels in the first place. Or DAC plants could pump the CO2 they produce into deep underground wells.

But the former would take up unreasonably large amounts of land to make a significant dent in emissions, while the latter would require huge amounts of already scant and expensive renewable power. According to a recent analysis, artificial photosynthesis could sidestep these issues because it’s up to five times more efficient than its natural counterpart and could be cheaper than DAC.

Whether the technology will develop quickly enough for it to be deployed at scale and in time to mitigate the worst effects of climate change remains to be seen. Emissions reductions certainly present a more sure-fire way to deal with the problem, but nonetheless, cyborg plants could soon be a common sight in our cities.

#435023 Inflatable Robot Astronauts and How to ...

The typical cultural image of a robot—as a steel, chrome, humanoid bucket of bolts—is often far from the reality of cutting-edge robotics research. There are difficulties, both social and technological, in realizing the image of a robot from science fiction—let alone one that can actually help around the house. Often, it’s simply the case that great expense in producing a humanoid robot that can perform dozens of tasks quite badly is less appropriate than producing some other design that’s optimized to a specific situation.

A team of scientists from Brigham Young University has received funding from NASA to investigate an inflatable robot called, improbably, King Louie. The robot was developed by Pneubotics, who have a long track record in the world of soft robotics.

In space, weight is at a premium. The world watched in awe and amusement when Commander Chris Hadfield sang “Space Oddity” from the International Space Station—but launching that guitar into space likely cost around $100,000. A good price for launching payload into outer space is on the order of $10,000 per pound ($22,000/kg).

For that price, it would cost a cool $1.7 million to launch Boston Dynamics’ famous ATLAS robot to the International Space Station, and its bulk would be inconvenient in the cramped living quarters available. By contrast, an inflatable robot like King Louie is substantially lighter and can simply be deflated and folded away when not in use. The robot can be manufactured from cheap, lightweight, and flexible materials, and minor damage is easy to repair.

Inflatable Robots Under Pressure
The concept of inflatable robots is not new: indeed, earlier prototypes of King Louie were exhibited back in 2013 at Google I/O’s After Hours, flailing away at each other in a boxing ring. Sparks might fly in fights between traditional robots, but the aim here was to demonstrate that the robots are passively safe: the soft, inflatable figures won’t accidentally smash delicate items when moving around.

Health and safety regulations form part of the reason why robots don’t work alongside humans more often, but soft robots would be far safer to use in healthcare or around children (whose first instinct, according to BYU’s promotional video, is either to hug or punch King Louie.) It’s also much harder to have nightmarish fantasies about robotic domination with these friendlier softbots: Terminator would’ve been a much shorter franchise if Skynet’s droids were inflatable.

Robotic exoskeletons are increasingly used for physical rehabilitation therapies, as well as for industrial purposes. As countries like Japan seek to care for their aging populations with robots and alleviate the burden on nurses, who suffer from some of the highest rates of back injuries of any profession, soft robots will become increasingly attractive for use in healthcare.

Precision and Proprioception
The main issue is one of control. Rigid, metallic robots may be more expensive and more dangerous, but the simple fact of their rigidity makes it easier to map out and control the precise motions of each of the robot’s limbs, digits, and actuators. Individual motors attached to these rigid robots can allow for a great many degrees of freedom—individual directions in which parts of the robot can move—and precision control.

For example, ATLAS has 28 degrees of freedom, while Shadow’s dexterous robot hand alone has 20. This is much harder to do with an inflatable robot, for precisely the same reasons that make it safer. Without hard and rigid bones, other methods of control must be used.

In the case of King Louie, the robot is made up of many expandable air chambers. An air-compressor changes the pressure levels in these air chambers, allowing them to expand and contract. This harks back to some of the earliest pneumatic automata. Pairs of chambers act antagonistically, like muscles, such that when one chamber “tenses,” another relaxes—allowing King Louie to have, for example, four degrees of freedom in each of its arms.

The robot is also surprisingly strong. Professor Killpack, who works at BYU on the project, estimates that its payload is comparable to other humanoid robots on the market, like Rethink Robotics’ Baxter (RIP).

Proprioception, that sixth sense that allows us to map out and control our own bodies and muscles in fine detail, is being enhanced for a wider range of soft, flexible robots with the use of machine learning algorithms connected to input from a whole host of sensors on the robot’s body.

Part of the reason this is so complicated with soft, flexible robots is that the shape and “map” of the robot’s body can change; that’s the whole point. But this means that every time King Louie is inflated, its body is a slightly different shape; when it becomes deformed, for example due to picking up objects, the shape changes again, and the complex ways in which the fabric can twist and bend are far more difficult to model and sense than the behavior of the rigid metal of King Louie’s hard counterparts. When you’re looking for precision, seemingly-small changes can be the difference between successfully holding an object or dropping it.

Learning to Move
Researchers at BYU are therefore spending a great deal of time on how to control the soft-bot enough to make it comparably useful. One method involves the commercial tracking technology used in the Vive VR system: by moving the game controller, which provides a constant feedback to the robot’s arm, you can control its position. Since the tracking software provides an estimate of the robot’s joint angles and continues to provide feedback until the arm is correctly aligned, this type of feedback method is likely to work regardless of small changes to the robot’s shape.

The other technologies the researchers are looking into for their softbot include arrays of flexible, tactile sensors to place on the softbot’s skin, and minimizing the complex cross-talk between these arrays to get coherent information about the robot’s environment. As with some of the new proprioception research, the project is looking into neural networks as a means of modeling the complicated dynamics—the motion and response to forces—of the softbot. This method relies on large amounts of observational data, mapping how the robot is inflated and how it moves, rather than explicitly understanding and solving the equations that govern its motion—which hopefully means the methods can work even as the robot changes.

There’s still a long way to go before soft and inflatable robots can be controlled sufficiently well to perform all the tasks they might be used for. Ultimately, no one robotic design is likely to be perfect for any situation.

Nevertheless, research like this gives us hope that one day, inflatable robots could be useful tools, or even companions, at which point the advertising slogans write themselves: Don’t let them down, and they won’t let you down!
