Blockchain Could Give People “Ownership of Their Own Data”

(p. B1) The first blockchain was created in 2009 as a new kind of database for the virtual currency Bitcoin, where all transactions could be stored without any banks or governments involved.
Now, countless entrepreneurs, companies and governments are looking to use similar databases — often independent of Bitcoin — to solve some of the most intractable issues facing society.
“People feel the need to move away from something like Facebook and toward something that allows them to have ownership of their own data,” said Ryan Shea, a co-founder of Blockstack, a New York company working with blockchain technology.
The creator of the World Wide Web, Tim Berners-Lee, has said the blockchain could help reduce the big internet companies’ influence and return the web to his original vision.
. . .
(p. B4) Blockstack has built a way to record the basic details about your identity on a blockchain database and then use that identity to set up accounts with other online projects that are built on top of it.
The animating force behind the project is that users — rather than Blockstack or any other company — would end up in control of all the data they generate with any online service.
Blockstack is one of several blockchain-based projects hoping to create a new generation of online services that don’t rely on having unfettered access to our personal information.
The idea has gained enough steam that in the days after news of Facebook’s relationship with Cambridge Analytica broke, Twitter was filled with people calling for blockchain-based alternatives.

Blockchain Tested to Speed Property Transfers

(p. B8) The blockchain technology that underpins cryptocurrencies such as bitcoin could change the way property deals are done and recorded more than any other new technology, real-estate and technology experts say.
And Sweden’s nearly 400-year-old land mapping and registration authority is likely to become one of the first government agencies to test using blockchain technology for conducting property sales.
The Lantmäteriet expects to conduct the first such transaction in the next few months and is shortlisting volunteers who want to buy or sell a property using the blockchain system. “From the technology point of view, we are quite ready,” said Mats Snäll, Lantmäteriet’s chief digital officer.
Proponents of blockchain say the technology would make recording and transferring titles faster and much more efficient. Transactions that today take months to complete could take days or even hours, they say.
Blockchain technology also is practically bulletproof when it comes to fraudulent transactions, experts say.

Government Obstacles Slow 5G Innovation

(p. A13) . . . , governmental obstacles threaten to block a new wave of wireless innovation, known as fifth generation or “5G.” It will multiply download speeds by at least 10 times, allowing wireless carriers to compete with cable companies for high-speed internet access. With superfast speeds and low lag times, 5G will enable advances in everything from driverless cars to the “tactile internet,” in which surgeons can perform operations and builders operate construction equipment remotely, and entertainment can include sensations beyond the audiovisual.
. . .
In some places, outdated local requirements prohibit carriers from placing small cells in local rights-of-way and on government-owned utility poles. Zoning ordinances designed for much larger towers often require local zoning boards to approve small cells. Some localities refuse altogether to negotiate right-of-way access, while others impose prohibitive fees and other unreasonable conditions.

“Overblown” Worries that A.I. Will Make Humans Obsolete

(p. B3) SAN FRANCISCO — Apple has hired Google’s chief of search and artificial intelligence, John Giannandrea, a major coup in its bid to catch up to the artificial intelligence technology of its rivals.
. . .
Mr. Giannandrea, a 53-year-old native of Scotland known to colleagues as J.G., helped lead the push to integrate A.I. throughout Google’s products, including internet search, Gmail and its own digital assistant, Google Assistant.
He joined Google in 2010 when it purchased Metaweb, a start-up where he served as chief technology officer. Metaweb was building what it described as a “database of the world’s knowledge,” which Google eventually rolled into its search engine to deliver direct answers to users’ queries. (Try googling “How old is Steph Curry?”) During Mr. Giannandrea’s tenure, A.I. research became increasingly important inside Google, with its primary A.I. lab, Google Brain, moving into a space beside the chief executive, Sundar Pichai.
. . .
On the debate over whether humanity should be worried about the rapidly accelerating improvements in A.I., Mr. Giannandrea told MIT Technology Review in an interview last year that the concerns were overblown.
“What I object to is this assumption that we will leap to some kind of superintelligent system that will then make humans obsolete,” he said. “I understand why people are concerned about it but I think it’s gotten way too much airtime. I just see no technological basis as to why this is imminent at all.”

Taboo Geoengineer Outlaws Could Counter Global Warming

(p. D3) A quarter-century ago, Pinatubo, a volcano in the Philippines, blew its top in a big way: It spewed a cubic mile of rock and ash and 20 million tons of sulfur dioxide gas into the atmosphere. The gas spread around the world and combined with water vapor to make aerosols, tiny droplets that reflected some sunlight away from the Earth. As a result, average global temperatures dropped by about one degree Fahrenheit for several years.
Powerful volcanic eruptions like Pinatubo’s in 1991 are one of the biggest natural influences on climate. So NASA researchers and other scientists are planning a rapid-response program to study the next big one.
But the climate impact of a Pinatubo-size eruption is also a natural analog of an idea that has existed on the fringes of science for years: geoengineering, or intervening in the atmosphere to deliberately cool the planet.
One geoengineering approach would use high-flying jets to spray similar chemicals in the stratosphere. So by studying the next big volcanic eruption, scientists would also gain insights into how such a scheme, known as solar radiation management, or S.R.M., might work.
“This is important if we’re ever going to do geoengineering,” said Alan Robock, a Rutgers University researcher who models the effects of eruptions and who has been involved in discussions about the rapid-response project.
. . .
Geoengineering has long had an outlaw image among much of the scientific community, viewed as risky last-resort measures to solve climate problems that would be better dealt with by cutting greenhouse gas emissions. Even discussing geoengineering concepts has long been considered taboo among many scientists.
. . .
But in the past few years, some scientists and policymakers have begun to argue for limited direct research into geoengineering concepts to better understand their potential as well as risks, and be better prepared should global warming reach a point where some kind of emergency action were deemed necessary.
A few scientists have proposed small-scale outdoor experiments to study aspects of solar radiation management, and last month the American Geophysical Union, one of the nation’s largest scientific societies, endorsed the idea of some research into what it called “climate intervention.”

Serial Breakthrough Innovators Have “Almost Maniacal Focus”

(p. C4) It’s 6 a.m., and I’m rushing around my apartment getting ready to fly to California to teach an innovation workshop, when my 10-year-old son looks at me with sad eyes and asks, “Why are you always busy?” My heart pounds, and that familiar knife of guilt and pain twists in my stomach. Then a thought flickers through my head: Does Jeff Bezos go through this?
I recently finished writing a book about innovators who achieved multiple breakthroughs in science and technology over the past two centuries. Of the eight individuals I wrote cases about, only one, Marie Curie, is a woman. I tried to find more, even though I knew in my scientist’s heart that deliberately looking for women would bias my selection process. But I didn’t find other women who met the criteria I had laid out at the beginning of the project.
. . .
The politically correct thing to say at this point is that expanding the roster of future innovators to include more women will require certain obvious changes in how we handle family life: Men and women should have more equal child-care responsibilities, and businesses (or governments) should make affordable, quality child care more accessible. But I don’t think it is as simple as that.
In my own case, I can afford more child care, but I don’t want to relinquish more of my caregiving to others. From the moment I first gave birth, I felt a deep, primal need to hold my children, nurture them and meet their needs. Nature is extremely clever, and she has crafted an intoxicating cocktail of oxytocin and other neurochemicals to rivet the attention of parents on their children.
The research on whether this response is stronger for mothers than for fathers is inconclusive. It is tough to compare the two, because there are strong gender differences in how hormones work. Historically, however, women have taken on a larger share of the caregiving responsibilities for children, and many (myself included) would not have it any other way.
Is such a view hopelessly retrograde, a rejection of hard-won feminist achievements? I don’t think so.
The need to connect with our children does not prevent women from being successful. There are many extremely successful women with very close relationships with their children. But it might get in the way of having the almost maniacal focus that the most famous serial breakthrough innovators exhibit.
I’m no Marie Curie, but I do have obsessive tendencies. If I did not have a family, I would routinely work until 4 a.m. if I had an interesting problem to chase down. But now I have children, and so at 5 p.m., I need to dial it back and try to refocus my attention on things like homework and making dinner. I cannot single-mindedly focus on my work; part of my mind must belong to the children.
This doesn’t mean that mothers cannot be important innovators, but it might mean that their careers play out differently. Their years of intense focus might start later, or they might ebb and surge over time. The more we can do to enable people to have nonlinear career paths, the more we will increase innovation among women–and productivity more generally.

Regulating A.I. “Is a Recipe for Poor Laws and Even Worse Technology”

(p. A27) “Artificial intelligence” is all too frequently used as a shorthand for software that simply does what humans used to do. But replacing human activity is precisely what new technologies accomplish — spears replaced clubs, wheels replaced feet, the printing press replaced scribes, and so on. What’s new about A.I. is that this technology isn’t simply replacing human activities, external to our bodies; it’s also replacing human decision-making, inside our minds.
The challenges created by this novelty should not obscure the fact that A.I. itself is not one technology, or even one singular development. Regulating an assemblage of technology we can’t clearly define is a recipe for poor laws and even worse technology.

Musk’s Slow Hunch May Be Undone by Smaller Satellites

(p. B3) SpaceX ‘s long-delayed Falcon Heavy rocket, slated for its maiden flight on Tuesday [February 6, 2018], faces uncertain commercial prospects and lacks a clear role in efforts to send U.S. astronauts back to the moon or deeper into the solar system.
The company conceived the rocket at the beginning of the decade, when SpaceX was an underdog fighting to increase its share of launches and needed a beefed-up alternative to a fleet of underpowered boosters. But after spending some $1 billion and grappling with five years of delays and huge technical challenges related to reliably harnessing power from 27 engines, the company is contending with significantly eroded commercial demand for such a potent heavy-lift booster.
The primary reason for the weakened demand is that both national security and corporate satellites continue to get smaller and lighter. So now, even if it performs as advertised, the Falcon Heavy might be Elon Musk’s biggest contrarian bet since he founded SpaceX over 15 years ago.

Politicians Build Costly Megaprojects to Burnish Their Legacy

(p. 14) Petroski, a professor of both engineering and history at Duke and the author of such books as “The Pencil” and “The Evolution of Useful Things,” brings an eye for the little things: what kinds of guardrails are best, how roads can be made safer through better signage, which paving materials last longest. One of his key lessons is that small thinking can be a virtue, because the history of infrastructure is a series of experimental and incremental improvements.
Local governments tried endless variations of asphalt and concrete before developing paving surfaces that didn’t produce excess dust or deteriorate quickly under rain and snow. They gradually built longer bridges, learning from earlier designs that worked, and that didn’t. They tried out different paint colors for lane markings, finding the ones that drivers could see best.
This little-things perspective is needed at a time when America’s infrastructure agenda is simultaneously characterized by grandiose ambitions and limited budgets. Money is tight, and infrastructure needs are going unaddressed. At the same time, despite funding limitations, politicians have a tendency to fall in love with novel, pathbreaking, expensive projects that frequently go astray, resulting in arguments against spending more on infrastructure.
. . .
Politicians aren’t drawn to megaprojects just because they believe the initial rosy cost projections and therefore underestimate the risk of complications. They also see an opportunity to build their legacy: It’s more fun to say “I built that bridge” than “I retrofitted that bridge.”

New Technology Reveals Fossil Secrets

(p. A11) Using a new laser imaging technique to reveal traces of soft tissue in fossils of an early feathered, birdlike dinosaur, scientists have found direct evidence of a wing structure needed for flight that was previously invisible from the preserved bone evidence.
The research is part of a body of work on the cutting edge of paleontology, leveraging new technology to flesh out the study of fossils beyond bones, to look at soft tissue and feathers. Other scientists have recently turned up evidence of the protein collagen preserved in dinosaur fossils millions of years old, and scanned feathers, muscle, skin and ligament tissue from a dinosaur’s tail preserved in amber.
Known as laser-stimulated fluorescence, the new imaging technique “is revealing information preserved in the fossil we can’t see with normal light,” says University of Hong Kong paleontologist Michael Pittman, one of the leaders of the research, published Tuesday [February 28, 2017] in Nature Communications.

Innovation Skeptics Fail to See Its Broad Benefits

(p. B11) Professor Juma died on Dec. 15 [2017] at his home in Cambridge, Mass. He was 64. His wife said the cause was cancer. At his death he was widely credited as having been an important force in ensuring that biotechnology would play a critical role in improving economic life in many developing countries, especially in sub-Saharan Africa.
“Calestous understood that people often resist the changes that come with innovation, and that overcoming this resistance can be very important in enabling societies to move ahead,” said Douglas W. Elmendorf, dean of the Kennedy School. “So he tried to understand why people resist innovation, and what can be done to make them feel comfortable with change.”
Professor Juma’s latest book, “Innovation and Its Enemies” (2016), described how technological change is often greeted with public skepticism. Beneath such opposition, he argued, is the belief that only a small segment of society will benefit from potential progress, while the much broader society bears the greatest risk.
. . .
Professor Juma could be lighthearted in the classroom or in public in order to make his points. With more than 100,000 followers on Twitter, he shared with them cartoons that teased skeptics of science and innovation. One of his last posts featured a game show called “Facts Don’t Matter.” In it, a contestant is told: “I’m sorry, Jeannie, your answer was correct, but Kevin shouted his incorrect answer over yours, so he gets the points.”
