A.I. Makes Surgeons More Efficient, but Does Not Replace Them

(p. B6) Brain surgeons are bringing artificial intelligence and new imaging techniques into the operating room, to diagnose tumors as accurately as pathologists, and much faster, according to a report in the journal Nature Medicine.

The new approach streamlines the standard practice of analyzing tissue samples while the patient is still on the operating table, to help guide brain surgery and later treatment.

The traditional method, which requires sending the tissue to a lab, freezing and staining it, then peering at it through a microscope, takes 20 to 30 minutes or longer. The new technique takes two and a half minutes. Like the old method, it requires that tissue be removed from the brain, but uses lasers to create images and a computer to read them in the operating room.

. . .

Some types of brain tumor are so rare that there is not enough data on them to train an A.I. system, so the system in the study was designed to essentially toss out samples it could not identify.

Over all, the system did make mistakes: It misdiagnosed 14 cases that the humans got right. And the doctors missed 17 cases that the computer got right.

“I couldn’t have hoped for a better result,” Dr. Orringer said. “It’s exciting. It says the combination of an algorithm plus human intuition improves our ability to predict diagnosis.”

In his own practice, Dr. Orringer said that he often used the system to determine quickly whether he had removed as much of a brain tumor as possible, or should keep cutting.

“If I have six questions during an operation, I can get them answered without having six times 30 or 40 minutes,” he said. “I didn’t do this before. It’s a lot of burden to the patient to be under anesthesia for that long.”

Dr. Bederson said that he had participated in a pilot study of a system similar to the one in the study and wanted to use it, and that his hospital was considering acquiring the technology.

“It won’t change brain surgery,” he said, “but it’s going to add a significant new tool, more significant than they’ve stated.”

Communist China Building “a Digital Totalitarian State”

(p. A1) ZHENGZHOU, China — China is ramping up its ability to spy on its nearly 1.4 billion people to new and disturbing levels, giving the world a blueprint for how to build a digital totalitarian state.

Chinese authorities are knitting together old and state-of-the-art technologies — phone scanners, facial-recognition cameras, face and fingerprint databases and many others — into sweeping tools for authoritarian control, according to police and private databases examined by The New York Times.

Once combined and fully operational, the tools can help police grab the identities of people as they walk down the street, find out who they are meeting with and identify who does and doesn’t belong to the Communist Party.

Greta Thunberg “Brushed Off” Need to Know Economics

(p. A7) DAVOS, Switzerland — Greta Thunberg, the 17-year-old Swedish climate activist, spent this week inside the halls of power at the World Economic Forum, . . .

. . .

Speaking to reporters just before the march set off, Ms. Thunberg and four youth activists from Europe and Africa rebuked business and government leaders at the World Economic Forum for not taking climate action and warned that they would continue to press them to stop investing in fossil fuels. Those demands, Ms. Thunberg noted, “have been completely ignored.”

Asked about a suggestion by Treasury Secretary Steven Mnuchin that she learn economics in college before calling for divestment, Ms. Thunberg brushed off such criticisms as irrelevant. “If we care about that, we wouldn’t be able to do what we do,” she said.

Clayton Christensen Wrote Well on Innovation

Clayton Christensen’s The Innovator’s Solution (co-authored with Michael Raynor) was packed with insights and examples on how entrepreneurs and incumbent firms innovate. He wrote several other thought-provoking and useful books, starting with his now-famous The Innovator’s Dilemma. Just a few days ago, I told one of my students from Africa that he should read Christensen’s latest book, which gives wonderful examples of how entrepreneurial innovation in developing countries can help them prosper.

This evening (Thurs., Jan. 24, 2020) I was discouraged to receive an email alert from the Wall Street Journal saying that Christensen died today.

A year or so ago, I sent him a late draft of my Openness to Creative Destruction, which references his work several times. He never responded. Maybe he already was too ill to look at it, or maybe he didn’t like it. I’ll never know. But either way, I thank him for all that his books taught me about innovation.

Flying Cars Face “a Long Road to Regulatory Approval”

(p. B3) Curtiss Autoplane. Fulton Airphibian. Taylor Aerocar.

Businesses and entrepreneurs have been promising a mass-produced flying car for more than a century. None have succeeded, but that hasn’t stopped Hyundai and Uber from wanting in on the action.

. . .

. . . there is a long road to regulatory approval. According to Morgan Stanley, air taxis will probably be used first in package delivery, which has fewer technical and regulatory barriers.

Facebook’s “Lord of the Rings” Defense of Free Speech

(p. B1) On Dec. 30, [2019] Andrew Bosworth, the head of Facebook’s virtual and augmented reality division, wrote on his internal Facebook page that, as a liberal, he found himself wanting to use the social network’s powerful platform against Mr. Trump. But citing the “Lord of the Rings” franchise and the philosopher John Rawls, Mr. Bosworth said that doing so would eventually backfire.

“I find myself desperately wanting to pull any lever at my disposal to avoid the same result,” he wrote. “So what stays my hand? I find myself thinking of the Lord of the Rings at this moment.

“Specifically when Frodo offers the ring to Galadrial and she imagines using the power righteously, at first, but knows it will eventually corrupt her,” he said, misspelling the name of the character Galadriel. “As tempting as it is to use the tools available to us to change the outcome, I am confident we must never do that or we will become that which we fear.”

Entrepreneurs Dream of Transportation Breakthroughs

(p. A13) “Hop, Skip, Go” seems to be the result of an extended reporting trip, during which the authors chat with would-be game-changers from Los Angeles to Helsinki to Dubai to Guangzhou, offering futuristic punditry along the way.

. . .

The authors have tracked down entrepreneurs who are following their dreams of shaking up passenger transportation. In Shanghai, we meet Joseph Xie, whose Shanghai Quality Sensor Technology Corp. specializes in tiny semiconductors that sense light, sound and motion and have a wide application for autonomous vehicles, among other uses. In the Detroit area, R.J. Scaringe’s company, Rivian, aims to build electric cars and recently captured a $500 million investment from Ford. In Helsinki, an engineering student named Sonja Heikkilä wrote a thesis proposing a mobility app that would allow subscribers access to every sort of conveyance, from dockless scooters to rental cars. Mark Moore, a former NASA researcher now with an Uber venture called Uber Air, envisions small aircraft allowing users to fly over traffic jams within a decade.

Venture Capitalist Don Valentine Was Rare Early Backer of Apple

(p. A9) In the mid 1960s, Don Valentine had a hunch that startups using silicon semiconductors, then a new technology, would thrive. After failing to persuade his employer, Fairchild Semiconductor Corp., that it should invest in some of its more promising customers, Mr. Valentine decided to invest on his own.

His hobby became Sequoia Capital, which over the following five decades has built an unrivaled record of venture capital investing, betting early on Atari and Apple Inc. in the 1970s, Cisco Systems Inc. and Oracle Corp. in the 1980s, Yahoo! and Google in the 1990s, Airbnb Inc. and LinkedIn Corp. in the 2000s, and Stripe Inc., Square Inc. and WhatsApp this decade.

Mr. Valentine handed the reins to a new generation of investors in 1996, but the firm still operates in his image—as a team of hard-nosed investors willing to butt heads inside company boardrooms and who relentlessly question each other and those seeking their capital.

. . .

Atari founder Nolan Bushnell says Mr. Valentine was by far his best board member. “We fought like cats and dogs,” recalled Mr. Bushnell. “Steel sharpens steel. Every board meeting, he would ask me a question about my company that I didn’t know but I immediately knew that I should know it.”

Mr. Bushnell introduced Mr. Valentine to a young Atari employee named Steve Jobs, who had an idea for a personal computer but whom other investors wouldn’t back, in part because of his messy appearance.

Mr. Valentine said in the 2009 interview that one of Sequoia’s secrets was its Socratic method, in which partners constantly questioned one another. He recalled in the same interview that Mr. Jobs stood out as one of the “best interrogators” he ever saw. “Somehow or other, he knew what to focus on and how to build a sequence and series of questions that were additive to the answers.”

Amazon Enables Flourishing of Small Diverse Entrepreneurs

(p. A24) They are a religious community known for clinging to 18th-century fashions and mores — strict rules that keep men and women apart and constraints on attire, with men favoring black suits and formal hats and women in long sleeves and long skirts.

But when it comes to doing business, Hasidic Jews have become enamored with a distinctly 21st-century company: Amazon.

The ability to sell merchandise easily and relatively anonymously on Amazon has transformed the economies of Hasidic enclaves in Brooklyn, suburban New York and central New Jersey, communities where members prefer to keep to themselves and typically do not go to college, let alone graduate from business programs.

But Amazon allows Hasidim to start selling without much experience and without making the investments required by a brick-and-mortar store. It permits Hasidic sellers to deal with the public invisibly — almost entirely by mail, by email or through package-delivery firms.

“Amazon doesn’t ask for your résumé,” said Sam Friedman, a marketer who designs trade show exhibits and works with many Amazon sellers. “And your picture is not on your business. The investment is minimal. You can work out of your bedroom.”

. . .

If Amazon is fulfilling orders, the business may effectively be running on Sabbath and Jewish holidays, though how that is carried out is the subject of vigorous debate. With a Talmudic twist of logic, some Hasidic entrepreneurs take on a non-Jew as a presumptive partner, attributing profits made on the Sabbath to that person.

. . .

Mr. Friedman is . . . organizing a business, advertising and marketing expo in Brooklyn in December [2019] to help Hasidic merchants expand their online sales by contracting with experienced copy writers, web designers, videographers and other professionals whose occupations the Talmudic Sages never even dreamed of.

“We’re not college students,” Mr. Friedman said, “but the yeshiva makes us smart enough to figure things out.”
