International Business Machines (IBM) is acquiring software maker Red Hat in a deal valued at $34 billion, the companies said Sunday. From a report: The purchase, announced on Sunday afternoon, is the latest competitive step among large business software companies to gain an edge in the fast-growing market for Internet-style cloud computing. In June, Microsoft acquired GitHub, a major code-sharing platform for software developers, for $7.5 billion. IBM said its acquisition of Red Hat was a move to open up software development on computer clouds, in which software developers write applications that run on remote data centers. From a press release: This acquisition brings together the best-in-class hybrid cloud providers and will enable companies to securely move all business applications to the cloud. Companies today are already using multiple clouds. However, research shows that 80 percent of business workloads have yet to move to the cloud, held back by the proprietary nature of today's cloud market. This prevents portability of data and applications across multiple clouds, data security in a multi-cloud environment and consistent cloud management.

IBM and Red Hat will be strongly positioned to address this issue and accelerate hybrid multi-cloud adoption. Together, they will help clients create cloud-native business applications faster, drive greater portability and security of data and applications across multiple public and private clouds, all with consistent cloud management. In doing so, they will draw on their shared leadership in key technologies, such as Linux, containers, Kubernetes, multi-cloud management, and cloud management and automation. IBM's and Red Hat's partnership has spanned 20 years, with IBM serving as an early supporter of Linux, collaborating with Red Hat to help develop and grow enterprise-grade Linux and more recently to bring enterprise Kubernetes and hybrid cloud solutions to customers. These innovations have become core technologies within IBM's $19 billion hybrid cloud business. Between them, IBM and Red Hat have contributed more to the open source community than any other organization.

harrymcc writes: The better AI gets at teaching itself to perform tasks in ways beyond the skills of mere humans, the more likely it is that it may unwittingly behave in ways a human would consider unethical. To explore ways to prevent this from happening, IBM researchers taught AI to play Pac-Man without ever gobbling up the ghosts. And it did so without ever explicitly telling the software that this was the goal. Over at Fast Company, I wrote about this project and what IBM learned from conducting it.

The researchers built a piece of software that could balance the AI's ratio of self-devised, aggressive game play to human-influenced ghost avoidance, and tried different settings to see how they affected its overall approach to the game. By doing so, they found a tipping point -- the setting at which Pac-Man went from seriously chowing down on ghosts to largely avoiding them.

PolygamousRanchKid shares a report from 9to5Mac: At the Jamf Nation User Conference, IBM has announced that it is open sourcing its Mac@IBM provisioning code. The code being open-sourced offers IT departments the ability to gather additional information about their employees during macOS setup and allows employees to customize their enrollment by selecting apps or bundles of apps to install.

Back in 2015, IBM discussed how it went from zero to 30,000 Macs in six months. In 2016, IBM said Apple products were cheaper to manage when you looked at the entire life cycle: "IBM is saving a minimum of $265 (up to $535 depending on model) per Mac compared to a PC, over a 4-year lifespan. While the upfront workstation investment is lower for PCs, the residual value for Mac is higher The program's success has improved IBM's ability to attract and retain top talent -- a key advantage in today's competitive market."

"According to CNET, TechCrunch and others, the Trump administration reportedly wants tech giants to make it easy for workers to take leaves of absence to help the government modernize," writes Slashdot reader kimanaw. From a report: White House officials on Monday planned to meet with tech giants including Google, Microsoft, Amazon and IBM, to discuss ways to make it easier for employees to take leaves of absence to help with government projects, according to The Washington Post. The administration reportedly hopes tech industry workers will be able to help modernize state and federal agencies and tackle challenges such as upgrading the veterans' health care system. Attracting tech talent may prove difficult for the Trump administration, which hasn't always seen eye to eye with Silicon Valley on issues such as the president's ban on travel from predominantly Muslim countries. However, White House officials believe tech workers are willing to "put politics aside." "This event on Monday is not just about our efforts, it's about our successor, and their successor after that," said one unnamed official, according to the Post. The White House didn't respond to a request for comment.

In a paper published Thursday in the journal Science, Dr. Sergey Bravyi and his team reveal that they've developed a mathematical proof which, in specific cases, illustrates the quantum algorithm's inherent computational advantages over classical. Engadget reports: "It's good to know, because results like this become parts of algorithms," Bob Sutor, vice president of IBM Q Strategy and Ecosystem, told Engadget. "They become part of decisions about how people will start to attack problems. Where will they try classical techniques? Where will they try quantum techniques? How will those interplay? How will they work back and forth together?" What's more, the proof shows that, in these cases, the quantum algorithm can solve the problem in a fixed number of steps, regardless of how many inputs are added. With a classical computer, the more inputs you add, the more steps it needs to take in order to solve. Such are the advantages of parallel processing.

"The main point of this paper is not that somehow we discover some incredibly important quantum algorithm, or some practical, interesting problem," Bravyi told Engadget. "We ask if we can separate a constant depth [between] quantum and classical algorithms. As we increase the problem size, the runtime of the quantum algorithm remains constant, but the total number of operations grows." As Bravyi points out, this new proof doesn't, in and of itself, solve any existing computational issues. Instead, "it gives us insight into what makes a quantum computers more powerful," he continued. "And hopefully in the future it will lead to more practical, useful algorithms."

An anonymous reader quotes a report from Bloomberg: Although the century-old technology has disappeared from most people's daily view, magnetic tape lives on as the preferred medium for safely archiving critical cloud data in case, say, a software bug deletes thousands of Gmail messages, or a natural disaster wipes out some hard drives. The world's electronic financial, health, and scientific records, collected on state-of-the-art cloud servers belonging to Amazon.com, Microsoft, Google, and others, are also typically recorded on tape around the same time they are created. Usually the companies keep one copy of each tape on-site, in a massive vault, and send a second copy to somebody like Iron Mountain. Unfortunately for the big tech companies, the number of tape manufacturers has shrunk over the past three years from six to just two -- Sony and Fujifilm -- and each seems to think that's still one too many.

The Japanese companies have said the tape business is a mere rounding error as far as they're concerned, but each has spent millions of dollars arguing before the U.S. International Trade Commission to try to ban the other from importing tapes to America. [...] The tech industry worries that if Sony or Fujifilm knocks the other out of the U.S., the winner will hike prices, meaning higher costs for the big cloud providers; for old-line storage makers, including IBM, HPE, and Quantum; and, ultimately, for all those companies' customers. [...] Although Sony and Fujifilm have each assured the trade commission that they could fill the gap if their rival's products were shut out of the U.S., the need for storage continues to grow well beyond old conceptions. Construction is slated to begin as soon as next year on the Square Kilometer Array, a radio telescope with thousands of antennas in South Africa and Australia meant to detect signals emitted more than 13 billion years ago. It's been estimated the project could generate an exabyte (1 billion gigabytes) of raw data every day, the equivalent of 300 times the material in the U.S. Library of Congress and a huge storage headache all by itself.

MIT Technology Review recently discussed new attempts to replace the standard 'QWERY' keyboard layout, including Tap, "a one-handed gadget that fits over your fingers like rubbery brass knuckles and connects wirelessly to your smartphone." It's supposed to free you from clunky physical keyboards and act as a go-anywhere typing interface. A promotional video shows smiling people wearing Tap and typing with one hand on a leg, on an arm, and even (perhaps jokingly) on some guy's forehead... But when I tried it, the reality of using Tap was neither fun nor funny. Unlike a conventional QWERTY keyboard, Tap required me to think a lot, because I had to tap my fingers in not-very-intuitive combinations to create letters: an A is your thumb, a B is your index finger and pinky, a C is all your fingers except the index.
The article also acknowledges the Dvorak Simplified Keyboard layout and other alternatives like the one-handed Twiddler keyboard, but argues that "neither managed to dent QWERTY's dominance." [W]hat if the future is no input interface at all? Neurable is a startup in Cambridge, Massachusetts, that's working on a way to type simply by thinking. It uses an electrode-dotted headband connected to a VR headset to track brain activity. Machine learning helps figure out what letter you're trying to select and anticipate which key you'll want next. After you select several keys, it can fill in the rest of the word, says cofounder and CEO Ramses Alcaide....

Then there's the device being built over at CTRL-Labs: an armband that detects the activity of muscle fibers in the arm. One use could be to replace gaming controllers. For another feature in the works, algorithms use the data to figure out what it is that your hands are trying to type, even if they're barely moving. CEO and cofounder Thomas Reardon, who previously created Microsoft's Internet Explorer, says this too is a neural interface, of a sort. Whether you're typing or dictating, you're using your brain to turn muscles on and off, he points out.
While a developer version will be shipped this year, Reardon "admits that it is still not good enough for him to toss his trusty mid-'80s IBM Model M keyboard, which he says still 'sounds like rolling thunder' when he types." But do any Slashdot readers have their own suggestions or experiences to share?

Can anything replace 'QWERTY' keyboards?

Microsoft said Wednesday it had joined the Open Invention Network (OIN), an open-source patent consortium. As part of it, the company has essentially agreed to grant a royalty-free and unrestricted license to its entire patent portfolio to all other OIN members. From the press release: By joining OIN, Microsoft is demonstrating its commitment to open source software (OSS) and innovation through collaborative development. With more than 2,650 members [Editor's note: the members include Google, IBM, Red Hat, and SUSE], including numerous Fortune 500 enterprises, OIN is the largest patent non-aggression community in history and represents a core set of community values related to open source licensing, which has become the norm. "Open source development continues to expand into new products and markets to create unrivaled levels of innovation. Through its participation in OIN, Microsoft is explicitly acknowledging the importance of open source software to its future growth," said Keith Bergelt, CEO of Open Invention Network. "Microsoft's participation in OIN adds to our strong community, which through its breadth and depth has reduced patent risk in core technologies, and unequivocally signals for all companies who are using OSS but have yet to join OIN that the litmus test for authentic behavior in the OSS community includes OIN participation."

Erich Andersen, Corporate Vice President and Chief IP Counsel at Microsoft, said, "Microsoft sees open source as a key innovation engine, and for the past several years we have increased our involvement in, and contributions to, the open source community. We believe the protection OIN offers the open source community helps increase global contributions to and adoption of open source technologies. We are honored to stand with OIN as an active participant in its program to protect against patent aggression in core Linux and other important OSS technologies."

An anonymous reader shares a report: Four years ago, IBM announced that it was investing $3 billion over the next five years into the future of nanoelectronics with a broad project it dubbed "7nm and Beyond." With at least one major chipmaker, GlobalFoundries, hitting the wall at the 7-nm node, IBM is forging ahead, using graphene to deposit nanomaterials in predefined locations without chemical contamination. In research described in the journal Nature Communications, the IBM researchers for the first time electrified graphene so that it helps to deposit nanomaterials with 97% accuracy.

"As this method works for a wide variety of nanomaterials, we envision integrated devices with functionalities that represent the unique physical properties of the nanomaterial," said Mathias Steiner, manager at IBM Research-Brazil. "We also can envision on-chip light detectors and emitters operating within a distinct wavelength range determined by the optical properties of the nanomaterial." As an example, Steiner explained that if you wanted to modify the spectral performance of an optoelectronic device, you could simply replace the nanomaterial while keeping the manufacturing process flow the same. If you take the method one step further, you could assemble different nanomaterials in different places doing multiple passes of assembly to create on-chip light detectors operating in different detection windows at the same time.

talonyx writes: D-Wave Systems, the contentious but scrappy maker of quantum annealing processors, has launched a cloud-based platform where developers can sign up for free and run problems on their quantum processor unit (QPU). There's an in-depth set of demos, documentation, and an open-source Python SDK to look at. "Leap is the latest addition to the quantum cloud -- services that virtualize quantum computing for almost anyone with a computer and a broadband connection to use," reports IEEE Spectrum. "Leap allows anyone to sign up, giving them one minute of time on a cloud-connected 2000Q each month. That might not sound like much, but a key advantage of quantum computing is to be able to solve in milliseconds problems like factoring large numbers, optimizing routes, or calculating molecular structures that could take traditional computers days or weeks."

"D-Wave estimates that each user's free minute of quantum computing time should be enough to run between 400 and 4,000 jobs each month," the report adds. "If developers want more, the company will charge commercial users $2,000 for one hour of access each month."

Tim Berners-Lee, the founder of the World Wide Web, thinks it's broken and he has a plan to fix it. The British computer scientist has announced a new project that he hopes will radically change his creation by giving people full control over their data. Tim Berners-Lee: This is why I have, over recent years, been working with a few people at MIT and elsewhere to develop Solid, an open-source project to restore the power and agency of individuals on the web. Solid changes the current model where users have to hand over personal data to digital giants in exchange for perceived value. As we've all discovered, this hasn't been in our best interests. Solid is how we evolve the web in order to restore balance -- by giving every one of us complete control over data, personal or not, in a revolutionary way. Solid is a platform, built using the existing web. It gives every user a choice about where data is stored, which specific people and groups can access select elements, and which apps you use. It allows you, your family and colleagues, to link and share data with anyone. It allows people to look at the same data with different apps at the same time. Solid unleashes incredible opportunities for creativity, problem-solving and commerce. It will empower individuals, developers and businesses with entirely new ways to conceive, build and find innovative, trusted and beneficial applications and services. I see multiple market possibilities, including Solid apps and Solid data storage.

Solid is guided by the principle of "personal empowerment through data" which we believe is fundamental to the success of the next era of the web. We believe data should empower each of us. Imagine if all your current apps talked to each other, collaborating and conceiving ways to enrich and streamline your personal life and business objectives? That's the kind of innovation, intelligence and creativity Solid apps will generate. With Solid, you will have far more personal agency over data -- you decide which apps can access it. In an interview with Fast Company, he shared more on Solid and its creation: "I have been imagining this for a very long time," says Berners-Lee. He opens up his laptop and starts tapping at his keyboard. Watching the inventor of the web work at his computer feels like what it might have been like to watch Beethoven compose a symphony: It's riveting but hard to fully grasp. "We are in the Solid world now," he says, his eyes lit up with excitement. He pushes the laptop toward me so I too can see. On his screen, there is a simple-looking web page with tabs across the top: Tim's to-do list, his calendar, chats, address book. He built this app -- one of the first on Solid -- for his personal use. It is simple, spare. In fact, it's so plain that, at first glance, it's hard to see its significance. But to Berners-Lee, this is where the revolution begins. The app, using Solid's decentralized technology, allows Berners-Lee to access all of his data seamlessly -- his calendar, his music library, videos, chat, research. It's like a mashup of Google Drive, Microsoft Outlook, Slack, Spotify, and WhatsApp. The difference here is that, on Solid, all the information is under his control. Every bit of data he creates or adds on Solid exists within a Solid pod -- which is an acronym for personal online data store. These pods are what give Solid users control over their applications and information on the web. Anyone using the platform will get a Solid identity and Solid pod. This is how people, Berners-Lee says, will take back the power of the web from corporations.

Starting this week, developers around the world will be able to start building their own decentralized apps with tools through the Inrupt site. Berners-Lee will spend this fall crisscrossing the globe, giving tutorials and presentations to developers about Solid and Inrupt. "What's great about having a startup versus a research group is things get done," he says. These days, instead of heading into his lab at MIT, Berners-Lee comes to the Inrupt offices, which are currently based out of Janeiro Digital, a company he has contracted to help work on Inrupt. For now, the company consists of Berners-Lee; his partner John Bruce, who built Resilient, a security platform bought by IBM; a handful of on-staff developers contracted to work on the project; and a community of volunteer coders. Later this fall, Berners-Lee plans to start looking for more venture funding and grow his team. The aim, for now, is not to make billions of dollars. The man who gave the web away for free has never been motivated by money. Still, his plans could impact billion-dollar business models that profit off of control over data. It's not likely that the big powers of the web will give up control without a fight.

A group called the Bandwidth Alliance, being led by Cloudflare, promises to reduce the price of bandwidth for many cloud customers. "The overall idea here is that customers who use both Cloudflare, which is turning eight years old this week, and a cloud provider that's part of this alliance will get a significant discount on their egress traffic or won't have to pay for it at all," reports TechCrunch. From the report: The alliance is open, and others may join still, but right now it includes virtually every major and minor cloud provider you've ever heard of -- with one exception. Current members include Automattic, Backblaze, Digital Ocean, DreamHost, IBM Cloud, Linode, Google, Google Cloud, Microsoft Azure, Packet, Scaleway and Vapor. Some of these will now offer free egress traffic to mutual customers with Cloudflare, while others will offer at least a 75 percent discount.

Why would these businesses choose to do away with what's a minor but high-margin business, though? "The argument that we made to them was a pretty simple argument: it makes sense for you to charge for transit when you are actually paying for it," [Cloudflare CEO and co-founder Matthew Prince] said. Most of the time, though, those costs are very minor and Cloudflare, thanks to his massive number of global peering locations, can ingest the traffic directly from the cloud provider with no middlemen involved.

A lawyer known for battling tech giants over the treatment of workers has set her sights on International Business Machines Corp. Bloomberg reports: Shannon Liss-Riordan on Monday filed a class-action lawsuit in federal court in Manhattan on behalf of three former IBM employees who say the tech giant discriminated against them based on their age when it fired them. Liss-Riordan, a partner at Lichten & Liss-Riordan in Boston, has represented workers against Amazon, Uber and Google and has styled her firm as the premier champion for employees left behind by powerful tech companies. "Over the last several years, IBM has been in the process of systematically laying off older employees in order to build a younger workforce," the former employees claim in the suit, which draws heavily on a ProPublica report published in March that said the company has fired more than 20,000 employees older than 40 in the last six years.

The lawsuit comes as IBM faces questions about its firing practices. In exhaustive detail, the ProPublica report made the case that IBM systematically broke age-discrimination rules. Meanwhile, the Equal Employment Opportunity Commission has consolidated complaints against IBM into a single, targeted investigation, according to a person familiar with it.

An anonymous reader shares a report: On a clear, warm night earlier this year, several dozen University of California, Berkeley students folded themselves into gray chairs for a three-hour class on how to think like blockchain entrepreneurs. The evening's challenge, presented by Berkeley City Councilmember Ben Bartlett, was to brainstorm how blockchain technology might be used to alleviate the city's growing homeless problem.

"We have at least 1,400 homeless people in our city, and that includes many right here at UC Berkeley," Bartlett told the class. "So how can we use blockchain to fund a new prosperity? That's a challenge I'd like you to take on." The course, taught by visiting professor and former venture capitalist Po Chi Wu, is among a growing number of classes and research initiatives on blockchain technology emerging at universities. Blockchain -- a method for creating and maintaining a global ledger of transactions that doesn't require a third-party middleman such as a bank, government or corporation -- is best known for its role in powering the virtual currency bitcoin. Applications for the technology are springing up in sectors including retail, humanitarian aid, real estate and finance. Although some analysts believe blockchain won't gain widespread adoption for another five or 10 years, companies like IBM, Facebook and Google are investing heavily in the technology -- and universities are taking note.

New York University, Georgetown and Stanford are among the institutions that offer blockchain technology courses to get students thinking about its potential uses and to better prepare them for the workforce. Job postings requiring blockchain skills ballooned by 200 percent in the first five months of this year, compared with the same period a year earlier, though they remain less than 1 percent of software development jobs, according to the research firm Burning Glass Technologies. Universities including MIT, Cornell, and Columbia are launching labs and research centers to explore the technology and its policy implications and seed the development of rigorous curricula on the topic.

An anonymous reader quotes a report from Fast Company: Today the [Berkeley-based startup Rigetti] launched a project in the mold of Amazon Web Services (AWS) called Quantum Cloud Services. "What this platform achieves for the very first time is an integrated computing system that is the first quantum cloud services architecture," says Chad Rigetti, founder and CEO of his namesake company. The dozen initial users Rigetti has announced include biotech and chemistry companies harnessing quantum technology to study complex molecules in order to develop new drugs. The particular operations that the quantum end of the system can do, while still limited and error-prone, are nearly good enough to boost the performance of traditional computers beyond what they could do on their own -- a coming milestone called quantum advantage. "My guess is this could happen anytime from six to 36 months out," says Rigetti.

So-called hybrid algorithms leveraging both systems are able to spot and correct some errors. And even imperfect results from quantum computers can be good enough in many cases, either flat-out exceeding what traditional computer technology can do, or producing results faster or cheaper. Rigetti has been playing this angle, creating a software development kit called Forest (because it's an ecosystem, says Chad) that allows programmers to access hybrid systems. Like other companies such as IBM, Rigetti has been allowing developers to access small-scale quantum computers online to essentially start working out how to program for them. [...] Rigetti is now inviting customers to apply for free access to these systems, toward the goal of developing a real-world application that achieves quantum advantage. As an extra incentive, the first to make it wins a $1 million prize.

Three months after the American Civil Liberties Union revealed that Amazon provided facial recognition technology to local law enforcement, a new report by The Intercept says that IBM collaborated with the New York City Police Department to develop a system that allowed officials to search for people by skin color, hair color, gender, age, and various facial features. VentureBeat: The Intercept and the National Institute's nonprofit Investigative Fund, citing "confidential corporate documents" and interviews with engineers involved with the project, write that IBM began developing the analytics platform roughly 10 years ago in partnership with New York's Lower Manhattan Security Initiative counterterrorist center, after an earlier experiment with the city of Chicago. Using "thousands" of photographs from roughly 50 cameras provided by the NYPD, its computer vision system learned from 16,000 points to identify clothing color and other bodily characteristics, in addition to potential threats like unattended packages, people entering off-limits areas, and cars speeding up against the flow of traffic.

GlobalFoundries has made a major strategy shift announcement. The contract maker of semiconductors says it is ceasing development of bleeding edge manufacturing technologies and stop all work on its 7LP (7 nm) fabrication processes, which will not be used for any client. From a report: Instead, the company will focus on specialized process technologies for clients in emerging high-growth markets. These technologies will initially be based on the company's 14LPP/12LP platform and will include RF, embedded memory, and low power features. Because of the strategy shift, GF will cut 5% of its staff as well as renegotiate its WSA and IP-related deals with AMD and IBM.

GlobalFoundries was on track to tape out its clients' first chips made using its 7 nm process technology in the fourth quarter of this year, but "a few weeks ago" the company decided to take a drastic strategical turn, says Gary Patton. The CTO stressed that the decision was made not based on technical issues that the company faced, but on a careful consideration of business opportunities the company had with its 7LP platform as well as financial concerns. On the heels of this announcement, AMD said today that it will move all of its 7nm production on both CPUs and GPUs to TSMC.

An anonymous reader shares a report: In recent months, Facebook, Google, IBM, Microsoft and others have aggressively lobbied officials in the Trump administration and elsewhere to start outlining a federal privacy law, according to administration officials and the companies. The law would have a dual purpose, they said: It would overrule the California law and instead put into place a kinder set of rules that would give the companies wide leeway over how personal digital information was handled. "We are committed to being part of the process and a constructive part of the process," said Dean Garfield, president of a leading tech industry lobbying group, the Information Technology Industry Council, which is working on proposals for the federal law. "The best way is to work toward developing our own blueprint." The efforts could set up a big fight with consumer and privacy groups, especially as companies like Facebook face scrutiny for mishandling users' personal data. Many of the internet companies depend on the collection and analysis of such data to help them target the online ads that generate the bulk of their revenue.

The economy continues to be a friendly place for job seekers today, and not just for the ultra-educated -- economists are predicting ever-improving prospects for workers without a degree as well. From a report: Recently, job-search site Glassdoor compiled a list of 15 top employers that have said they no longer require applicants to have a college degree. Companies like Google, Apple, IBM and EY are all in this group. In 2017, IBM's vice president of talent Joanna Daley told CNBC Make It that about 15 percent of her company's U.S. hires don't have a four-year degree. She said that instead of looking exclusively at candidates who went to college, IBM now looks at candidates who have hands-on experience via a coding boot camp or an industry-related vocational class.

Can Watson cure cancer? That's what IBM asked soon after its AI system beat humans at the quiz show "Jeopardy!" in 2011. Watson could read documents quickly and find patterns in data. Could it match patient information with the latest in medical studies to deliver personalized treatment recommendations? "Watson represents a technology breakthrough that can help physicians improve patient outcomes," said Herbert Chase, a professor of biomedical informatics at Columbia University, in a 2012 IBM press release. Six years and billions of dollars later, the diagnosis for Watson is gloomy [Editor's note: the link may be paywalled; alternative source]. WSJ: More than a dozen IBM partners and clients have halted or shrunk Watson's oncology-related projects. Watson cancer applications have had limited impact on patients, according to dozens of interviews with medical centers, companies and doctors who have used it, as well as documents reviewed by The Wall Street Journal. In many cases, the tools didn't add much value. In some cases, Watson wasn't accurate. Watson can be tripped up by a lack of data in rare or recurring cancers, and treatments are evolving faster than Watson's human trainers can update the system. Dr. Chase of Columbia said he withdrew as an adviser after he grew disappointed in IBM's direction for marketing the technology. No published research shows Watson improving patient outcomes. IBM said Watson has important cancer-care benefits, like helping doctors keep up with medical knowledge.
