The world needs an international treaty to protect people’s privacy from unfettered cybersurveillance, which is being pushed by populist politicians preying on fear of terrorism, according to a U.N. report debated on Wednesday.

The report, submitted to the U.N. Human Rights Council by the U.N. independent expert on privacy, Joe Cannataci, said traditional privacy safeguards such as rules on phone tapping were outdated in the digital age.

“It’s time to start reclaiming cyberspace from the menace of over-surveillance,” Cannataci told the Council.

With governments worldwide demanding data from firms such as Microsoft, Google, Facebook, Apple and Twitter, it did not make sense to rely entirely on U.S. legal safeguards, and creating an “international warrant” for data access or surveillance would unify global standards, he said.

“What the world needs is not more state-sponsored shenanigans on the Internet but rational, civilized agreement about appropriate state behavior in cyberspace,” the report said. “This is not utopia. This is cold, stark reality.”

Cannataci was appointed as the first “Special Rapporteur on the right to privacy” in 2015, following the uproar caused by revelations by Edward Snowden, a former U.S. security contractor who once worked at the U.S. mission in Geneva.

His report was submitted last week, before the latest publication by anti-secrecy group WikiLeaks of what it said were thousands of pages of internal CIA discussions of hacking techniques of smartphones and other gadgets.

The United States did not react to Cannataci’s report, but many countries welcomed it and agreed that online privacy standards should be as strong as offline standards.

China’s diplomat at the Council said rapid technological advances and the “drastic increase worldwide in the violation of privacy” made it urgent to enhance protection, while Russia’s representative said Cannataci’s report was “extremely topical”.

Venezuela, Iran and Cuba all welcomed Cannataci’s work and criticized international surveillance.

A draft legal text was being debated by activists and “some of the larger international corporations” and was expected to be published within a year, Cannataci said.

In his report, he criticized populist laws that intruded on privacy in the name of fighting terrorism.

He said such sweeping but unproven powers were based on fear alone, and compared them to U.S. President Donald Trump’s order restricting travel from six Muslim-majority countries: Iran, Libya, Syria, Somalia, Sudan and Yemen.

“The level of the fear prevents the electorate from objectively assessing the effectiveness of the privacy-intrusive measures proposed,” he wrote.

“Trying to appear tough on security by legitimizing largely useless, hugely expensive and totally disproportionate measures which are intrusive on so many people’s privacy – and other rights – is patently not the way governments should go.”

When the Trump administration issued its executive order in Janurary restricting travelers from certain countries, many tech companies and their employees were quick to express their objections.

But now, with the new executive order out limiting travel to the U.S. for people from six countries, the response from Silicon Valley has been largely muted.

Alphabet, the parent company of Google, Facebook and Microsoft has so far remained quiet.

In reaction to the first travel executive order, the three companies were among 100 U.S. tech firms that filed a legal brief in opposition. At the time, Google said 76 of its employees were affected by the executive order.

Still, some firms, such as Uber, Lyft, Mozilla and Airbnb, were quick to express their objections to Monday’s executive order.

Lyft, the ride-hailing firm, plans to meet with the American Civil Liberties Group this week to discuss how “we can further support their efforts,” Logan Green, Lyft’s CEO, said in a statement. The company gave the civil liberties organization $1 million in January.

“Our sentiment has not changed: President (Donald) Trump’s immigration ban is unjust and wrong,” an Uber spokesperson said. “We will continue to stand up for those in the Uber community affected.”

Salesforce CEO Marc Benioff tweeted a tribute to his grandfather, “Thinking of great grandfather Issac Benioff who came to US from Kiev as Refugee. W/O him no @Salesforce (2M jobs/200B GDP) or@GameOfThrones!” (Benioff’s cousin, David, is the co-creator of the hit TV series.)

Tech lobbying group and trade organizations have largely stayed mum about the limited travel ban.

One exception is TechNet, which represents tech firms such as Facebook and Apple. It put out a statement this week saying that “unfortunately, just like the first order, this new policy singles out individuals based on their country of origin and will adversely impact technology workers who live and work in our nation.”

The industry has been anxiously waiting for the Trump administration’s revamp of the H-1B visa program, which Silicon Valley uses to hire skilled workers. Late last week, the administration jettisoned an aspect of the H-1B visa application process called “premium processing,” which allowed companies to pay extra for their visa applications to be expedited.

That change underscored the uncertainty in the industry over how the Trump administration will ultimately handle both work visas and travel restrictions.

“What’s next?” said Evan Engstrom, executive director of Engine, an advocacy and research group focused on tech startups.

“What everyone is concerned about is what anti-immigration policies are going to be more expansive,” Engstrom said.

It’s a point echoed by a Yahoo executive.

“American businesses like Yahoo need certainty, particularly around the ability to hire and retain top talent. A piecemeal approach leaves question marks for companies and employees,” April Boyd, a Yahoo vice president and head of global public policy, said in a statement. “We encourage the administration to work with Congress on a thoughtful, lasting approach to bring positive change to the current immigration system.”

Each April 1, the U.S. holds a lottery for 65,000 H-1B visas and 20,000 additional visas for foreign students with master’s degrees. Last year, there were requests for more than 200,000, a record figure.

But critics say skilled-worker visa programs have hurt American workers. Companies have used them, they say, to hire foreign workers who are not highly skilled and who are paid lower than market rate wages.

The biggest users of the H-1B program have been outsourcing firms that provide IT consulting.

Staying up late into the night, Lilia Lobato Martinez watched endless YouTube videos to teach herself the computer code she used to help build her prize-winning Ool app for volunteers in Guadalajara, Mexico.

In her country, she is usually the only woman in tech competitions, which often hand out men’s T-shirts to the winners.

Now the 18-year-old electrical engineering student is using the $10,000 she won for her app in last year’s international girls-only Technovation competition to further develop Ool, which has so far linked over 1,000 volunteers with 20 non-profit groups in Mexico’s second-biggest city.

“A lot of people were constantly complaining everything’s wrong, but I found that no one was going out to the street to volunteer,” said Lobato. “So I decided to develop an app that’s a compendium of all the non-profit organizations, so we can learn what Mexico is building.”

A male-dominated field

With plans to eventually set up a center to teach children to code, she said many of her female friends shied away from IT development because it was male-dominated. Only four out of 40 students on her degree course are women, she pointed out.

Across Latin America, the participation of girls and women in technology and science has lagged far behind men, experts say.

And while awareness of the need to correct the imbalance is growing, social and economic pressures mean many are still pushed into other areas or expected to start work straight after school rather than going into higher education.

“Boys think it’s easy for them and they expect to be smart in technology … it’s not expected for girls, and that’s reinforced by the education system quite often,” said Gloria Bonder, Buenos Aires-based UNESCO chair on women, science and technology in Latin America.

The portrayal of women in the media, and a lack of role models also contribute to making it a system-wide problem, added Bonder, who is working on a Central American pilot project to incorporate gender equality into science and technology education.

While 44 percent of all science research positions — including social sciences — in the region are held by women, they are under-represented in science, technology, engineering and maths (STEM), according to UNESCO.

For example, in Peru and Colombia, around a third of natural science researchers are women, but they account for just a quarter of engineering and technology researchers.

Now a number of projects are striving to improve access for girls and give them the skills and confidence to compete in those jobs.

Developers’ boot camp

One of these is the Laboratoria coding academy in Lima, which spots talent “where no one else is looking,” said its chief executive, Mariana Costa Checa.

More than 1,000 women applied for 70 places at its intensive boot camp where candidates from low-income backgrounds train as front-end web developers.

The application process involves a series of rigorous tests, alongside interviews with candidates’ families to reduce the drop-out rate for the course, which also runs in Santiago, Mexico City and the Peruvian city of Arequipa, and helps participants land jobs with companies such as IBM.

Along with computer programs like JavaScript, it teaches workplace skills that are crucial for women who have little experience of formal-sector employment, said Costa.

She expects some Laboratoria graduates will go on to develop technical solutions for problems in their communities.

“The first thing we look for is a job, because it gives them economic stability, and for our average student, it triples their income,” said Costa.

It also gives them “a new perspective in life,” she added. “It starts changing the way they look at the world — and I think there’s enormous value in then bringing that change to their own communities.”

Many girls are on their own

With many girls from poor families under pressure to start earning as soon as they finish school, Rebeca Vargas, president of the U.S.-Mexico Foundation, said most of those who signed up for the international STEM mentoring program she helped set up in Mexico’s Puebla state did so without telling their parents.

Nearly all are now studying STEM subjects at college or university.

“Some of the girls we worked with last year had to sell bread and food on the street to be able to earn money to eat,” said Vargas, whose foundation developed the program with Mexico’s public education secretariat and the New York Academy of Sciences.

Girls take a different route

Families often expect girls to pay their way at home but not to seek senior positions at corporations or well-paid jobs.

“They’re supposed to work but they’re not supposed to be educated,” Vargas said.

Wendy Arellano Martinez, who won a scholarship to study biotechnology engineering at the prestigious Monterrey Technology Institute after the mentoring program, is now part of a team developing a project to make  spectacle frames from recycled plastic bottles for older people on low incomes.

“We’re going to be looking for funds from organizations or foundations to help us distribute our products to people who need them but don’t have the resources,” said the 18-year-old student from Puebla. “I want to give the same support that I received.”

A German court rejected a temporary injunction against Facebook on Tuesday in a case brought by a Syrian refugee who sued the social networking site for failing to remove faked posts linking him to crimes and militant attacks.

The Wuerzburg district court said in a preliminary ruling that Facebook is neither a “perpetrator nor a participant” in what it said was “undisputable defamation” by Facebook users, but simply acting as a hosting provider that is not responsible for preemptively blocking offensive content under European law.

The posts in dispute featured a picture showing Anas Modamani, a 19-year-old from Damascus, taking a selfie with Chancellor Angela Merkel in September 2015 at a refugee shelter in the Berlin district of Spandau.

Modamani’s image was subsequently shared on Facebook on anonymous accounts, alongside posts falsely claiming he was responsible for the Brussels airport bombing of March 2016 and setting on fire a homeless man in December last year by six migrants at an underground station in Berlin.

The court rejected the need for a temporary injunction sought by Modamani to require Facebook to go beyond measures the company had taken to block defamatory images of him for Facebook users in Germany using geo-blocking technology.

In a statement following the decision, Facebook expressed concern for Modamani’s predicament but said the court’s ruling showed the company acted quickly to block access to defamatory postings, once they had been reported by Modamani’s lawyer.

The case has been closely watched as Germany, a frequent critic of Facebook, is preparing legislation to force the social networking website to remove “hate speech” from its web pages within 24 hours or face fines.

After the ruling, Modamani’s lawyer in the case, Chan-jo Jun, told a news conference he was disappointed such imagery continued to circulate online and more must be done to force Facebook to delete hate-filled content on its own accord.

“We have to decide whether we want to accept that Facebook can basically do whatever it wants or whether German law, and above all the removal of illegal contents in Germany, will be enforced. If we want that we need new laws,” Jun said.

Modamani’s complaint maintained that defamatory images based on the selfie posted to Facebook were still viewable online outside of Germany, or by users within Germany using a sophisticated Tor browser.

But the court found that the risk of average German users seeing the illegal content was not sufficiently credible and therefore a temporary injunction was unnecessary at this stage.

The ruling said there remained a legitimate issue over whether it was technically feasible for Facebook to do more to block such images, but this would require testimony by experts.

Tuesday’s decision is subject to appeal within one month of the yet-to-be-published written judgment, a court statement said. Jun declined to say whether an appeal was planned, saying the decision remained up to his client.

Facebook has launched a tool it says will help flag so-called fake news.

The tool adds a “disputed news” flag on stories that have been deemed fake by what Facebook says are third parties, including Snopes, Politifact and Factcheck.org.

Facebook announced the disputed news flag in December, but it appears it only has gone live in the past day or so, according to news reports.

If a story is flagged by some of Facebook’s 1.86 billion users, the company will determine which to send to the third parties. If the story is fake, it will still be on Facebook, but will carry a notice that it was disputed along with an explanation about why.

Disputed stories can still be shared, but users will be warned they are sharing fake news.

According to USA Today, one fake news story about how President Trump’s Android phone was the source of White House leaks came from a fake news site called “The Seattle Tribune.” The story now appears with a disputed flag as well as links to third party explanations as to why.

A May 2016 survey from the Nieman Lab said 44 percent of Americans get their news from Facebook.

From lasers that cut denim at a factory, to drones that irrigate crops, it’s not a new story that machines are doing more work than ever. But people have long feared that robots are coming for their jobs, so technology evangelists now are calling on their peers to build a future in which the impact on human is lessened.

Tim O’Reilly, the founder of O’Reilly Media, a technology consulting company, thinks the solution is a “hybrid,” mixing humans and machines. He sees that happening already. O’Reilly says most software, for example, is actually a service that depends on human beings in the background to keep it updated and running.

This could be a paradigm shift for Silicon Valley acolytes. Out with the old: a reputedly cold, relentless push for efficiency through algorithms and automation, no matter the consequences for the working class. In with the new: innovation with a human face.

“It’s so important that we have to think about not using technology to replace people — but to augment them, to do something that was previously impossible,” O’Reilly said last week in Ho Chi Minh City at Apricot, an annual summit organized by the Asia and Pacific Internet Association and APNIC, the regional registry for domain names.

With more skills, people can work alongside robots. Lyft and Uber rely on software that’s intended to make drivers more productive. They’re not completely different from airplanes, which are flown mostly by computers, but there might never be a day when passengers feel comfortable flying without at least one human at the helm.

Jonathan Brewer, a trainer at the nonprofit Network Startup Resource Center, believes the next stage of development should improve on the one before it, when the exploding numbers of factories and machines left so many people with undrinkable water and unbreathable air. Now, he said, technophiles must consider how their inventions help people. 

At an Apricot workshop, Brewer described sensors that alert residents an hour before a mudslide will hit, for example, and other “life-saving devices that cost very, very little money.”He says there doesn’t seem much point in having droids to clear tables and dig up copper ore if humans aren’t in a position to use the results of their labor.

O’Reilly illustrated the hybrid approach with the so-called Mechanical Turk. Not Amazon’s tool to outsource small tasks, but the 18th-century machine that seemed to beat humans at chess. In fact, there was a man inside all along, and that is the point. Looking out over an audience of programmers, engineers, and other operators building the internet, O’Reilly compared them to the Mechanical Turk: The world needs workers powered by blood, not just those powered by batteries.

“All of you, in some sense, are inside the internet. You go away, it stops working,” he said. “It’s not like a piece of software in a PC era where if you had a copy of Microsoft Windows running on your personal computer, it would keep running without the original programmers. Almost all of the software we depend on today is a service that depends on the work of people like you.”

There may be some wishful thinking, too, in technologists’ optimism that humans will thrive in the robot future. In 2015, consulting firm McKinsey projected that automation could eliminate 45 percent of today’s occupations. That’s why more people in the technology sector are warming to the idea of a universal basic income, which shares the benefits of innovation by giving each citizen a small monthly check.

But Brewer holds out hope in cooperation between people and machines. Many advancements don’t just make lives easier, such as thermostats that adjust the temperature to a dweller’s liking. He said there is technology, for example, that lets city employees know when street lights go out, or trash cans are full, so they don’t have to drive around checking manually, which many local governments do. But once the notice is sent, a human still needs to respond and ensure services are delivered.

For technology, conference-goers said, early adopters first embraced the inexorable, unsympathetic march of change as an indisputable benefit. But in this next phase, people are rethinking disruption, or at least wondering how to soften the blow on humans.

A pair of $250,000 autonomous buses began driving around an empty San Francisco Bay Area parking lot on Monday, preparing to move onto a local public road in California’s first pilot program for a self-driving vehicle without steering wheel or human operator.

California and other states are weighing the opportunities of becoming a hub of testing a technology that is seen as the future of transportation and the risks from giving up active control of a large, potentially dangerous vehicle.

In most tests of self-driving cars there is still a person seated at the steering wheel, ready to take over, although Alphabet Inc’s Waymo tested a car with no steering wheel or pedals in Austin, Texas, as early as 2015.

The bus project in San Ramon, at the Bishop Ranch office park complex, involves two 12-passenger shuttle buses from French private company EasyMile.

The project is backed by a combination of private companies and public transit and air quality authorities, with the intention of turning it into a permanent, expanded operation, said Habib Shamskhou, a program manager who strolled in front of a moving bus to show that the vehicle would notice him and react. It stopped.

In a test for reporters, one bus cruised a block-long circuit so consistently that it created a dirt track on the tarmac.

California legislators late last year passed a law to allow slow-speed testing of fully autonomous vehicles without steering wheels or pedals on public roads, with the Bishop Ranch test in mind.

The shuttle buses will test for a few months in the parking lots before operators apply for Department of Motor Vehicles approval under the new law. The vehicles are expected to swing onto the local street late this year or early in 2018.

Young adults who spend a lot of time looking for social connections on social media could instead find themselves feeling socially isolated, a new study suggests.

Researchers looked at the social media habits of 1,787 American adults aged 19 to 32, asking them how much they used 11 popular social media sites, including Facebook, YouTube, Instagram, Snapchat, Twitter and LinkedIn, among others.

After controlling for various demographic factors, they found that people who used social media more than two hours per day “had twice the odds for perceived social isolation than their peers who spent less than half an hour on social media each day.”

Those who visited social media sites 58 times a week or more “had about triple the odds of perceived social isolation than those who visited fewer than nine times per week.”

Writing in the American Journal of Preventative Medicine, researchers from the University of Pittsburgh School of Medicine add that increased social isolation has been associated with “an increased risk for mortality.”

“This is an important issue to study because mental health problems and social isolation are at epidemic levels among young adults,” said lead author Dr. Brian A. Primack, director of Pitt’s Center for Research on Media, Technology and Health. “We are inherently social creatures, but modern life tends to compartmentalize us instead of bringing us together. While it may seem that social media presents opportunities to fill that social void, I think this study suggests that it may not be the solution people were hoping for.”

“We do not yet know which came first, the social media use or the perceived social isolation,” said senior author Dr. Elizabeth Miller, professor of pediatrics at Pitt and chief of the Division of Adolescent and Young Adult Medicine at Children’s Hospital of Pittsburgh of UPMC.

“It’s possible that young adults who initially felt socially isolated turned to social media. Or it could be that their increased use of social media somehow led to feeling isolated from the real world. It also could be a combination of both. But even if the social isolation came first, it did not seem to be alleviated by spending time online, even in purportedly social situations.”

Researchers social media may cause feelings of social isolation by replacing “authentic social experiences;” causing feelings of exclusion stemming from seeing photos of friends having fun at events to which they were not invited; or may lead people to think others have happier or more successful lives due to often idealized presentation of one’s life online.

Researchers say more study needs to be done, but they say doctors should ask patients about social media use if they show symptoms of social isolation.

“People interact with each other over social media in many different ways,” said Primack, “In a large population-based study such as this, we report overall tendencies that may or may not apply to each individual. I don’t doubt that some people using certain platforms in specific ways may find comfort and social connectedness via social media relationships. However, the results of this study simply remind us that, on the whole, use of social media tends to be associated with increased social isolation and not decreased social isolation.”

Oil and gas companies, including some of the most celebrated industry names in the Houston area, are facing increasingly sophisticated hackers seeking to steal trade secrets and disrupt operations, according to a newspaper investigation.

A stretch of the Gulf Coast near Houston features one of the largest concentrations of refineries, pipelines and chemical plants in the country, and cybersecurity experts say it’s an alluring target for espionage and other cyberattacks.

“There are actors that are scanning for these vulnerable systems and taking advantage of those weaknesses when they find them,” said Marty Edwards, director of U.S. Homeland Security’s Cyber Emergency Response Team for industrial systems.

Homeland Security, which is responsible for protecting the nation from cybercrime, received reports of some 350 incidents at energy companies from 2011 to 2015, an investigation by the Houston Chronicle has found. Over that period, the agency found nearly 900 security flaws within U.S. energy companies, more than any other industry.

Steps are being taken to thwart attacks. For instance, the Coast Guard in a joint operation with Houston police patrolled the waters southeast of Houston last year conducting sweeps for unprotected wireless signals that hackers could use to gain access to facilities. The operation was one of the first of its kind in the U.S. concentrating on cyberattacks by sea.

But the vast network of oil and gas operations makes it difficult to secure. Thousands of interconnected sensors and controls that run oil and gas facilities remain rife with weak spots.

Many companies the technology and personnel to detect hackers. Equipment was designed decades ago without security features, and efforts over the years to link computer networks to devices that monitor pressure or control valves have exposed operations to online threats.

“You could mess with a refinery or cause a vessel to explode,” Richard Garcia, a former FBI agent who became a cybersecurity specialist, told the Chronicle.

Power, chemical and nuclear facilities must adhere to strict cybersecurity measures, but federal law doesn’t impose such standards on the oil and gas sector. And when oil and gas companies have been infiltrated by a hacker, they’re not required to report the incident.

More than 20 of the nation’s largest oil companies _  including Exxon Mobil Corp. and ConocoPhillips, refiner Phillips 66 and pipeline operator Kinder Morgan _ declined to comment or did not respond to multiple requests for comment. The American Petroleum Institute, the national trade association for oil and gas, also declined to comment.

Charles McConnell, executive director of Rice University’s Energy and Environment Initiative, said oil companies tend to rush to deploy new computer technologies that make operations more productive, but only afterward considering ways to defuse online threats.

“The pace of change of the technology we’ve adopted is every step of the way more and more vulnerable to cyberattack,” McConnell said.

Twitter introduced new safety measures this week meant to crack down on online harassment and protect people from viewing offensive material, but some free-speech advocates are concerned the changes could lead to censorship of unpopular ideas.

The social media company announced Wednesday that it would start hiding potentially menacing tweets, even if the tweets or accounts in question hadn’t been reported as abusive.

“We’re working to identify accounts as they’re engaging in abusive behavior, even if this behavior hasn’t been reported to us,” the company said in a statement announcing the changes. “Then, we’re taking action by limiting certain account functionality for a set amount of time, such as allowing only their followers to see their Tweets.”

The so-called stealth bans could be placed on accounts, the company’s statement said, if a Twitter user sent unsolicited messages to another user who was not following the sender.

Twitter said it would “act on accounts” only when it was confident abuse had taken place, based on the algorithms it uses to identify illicit posts.

This new automated stealth ban capability became a cause of consternation for Suzanne Nossel, executive director of the free-speech advocacy group PEN America, because she said it could easily become a solution “where there is really no problem that needs to be solved.”

‘Mistaken’ moves?

“To take action when there hasn’t been a complaint raises the concern of whether there will be mistaken blocking of accounts or suspending of accounts,” she said. “That raises a risk.”

Twitter has been under pressure to address abusive speech and trolling on its platform in recent months after celebrities and others complained of sustained, coordinated abuse campaigns.

Actress Leslie Jones notably swore off the social media service for a brief time last year after she was targeted by online trolls and harassed with racism and death threats. The incident led to a personal meeting between Jones and Twitter CEO Jack Dorsey, and several months later the company began introducing new tools to address online abuse.

Twitter expanded its “mute” feature to allow users to block specific words or phrases from showing up in their notifications. It expanded users’ ability to report hateful conduct. And it retrained its support teams on dealing with online abuse.

These types of changes that allow users to have more control over what content they see and whom they interact with are positive steps, Esha Bhandari, a staff attorney with the American Civil Liberties Union’s Speech, Privacy, and Technology Project, told VOA.

Control for users

The ACLU encourages companies to focus less on a top-down approach to censorship and more “on tools that allow users to control their experience on the platform,” she said.

“Attempts to put the thumb on the scale on the censorship side are prone to error and prone to human biases,” Bhandari said.

Newer tools introduced by Twitter, though, give the company a far greater role in controlling what content gets seen.

In February, Twitter began pre-emptively hiding what it called “potentially abusive or low-quality tweets” from conversations on the website. The tweets will still be visible to users, but only to “those who seek them out.”

“Our team has also been working on identifying and collapsing potentially abusive and low-quality replies so the most relevant conversations are brought forward,” Twitter said in a February statement.

VOA contacted Twitter multiple times for clarification on guidelines used to identify “low-quality” tweets but received no response.

Twitter also introduced a “safe search” feature in February that automatically removes tweets that contain “potentially sensitive content” from search results. A request for clarification on how this content is identified was not returned.

Being a private company, Twitter has no real obligation to preserve free speech on its website. But Twitter has billed itself as a platform for free expression, and on the Twitter rules page, it says it believes in “speaking truth to power.”

Global town square

This is a role both PEN America and the ACLU take seriously. Both Nossel and Bhandari referred to the website as a sort of global town square, where everyone’s voice has equal weight.

“As a practical matter, decisions made by Twitter have a huge impact on the messages that we receive, and I hope that Twitter and other companies take those responsibilities seriously,” Bhandari said.

Nossel noted that Twitter has a financial incentive to be cautious on issues involving the balance between allowing free expression and stopping abuse.

“The power and influence of their platform depends on the free flow of ideas, so I think there are commercial reasons why they would not want to limit [free speech],” she said. “And I think for their users, they do have a kind of softer, implicit contract that they are going to be a platform in which you can express things freely.”

Bhandari said it’s important to find that balance, because if Twitter “allows a heckler’s veto to take over,” it will have a chilling effect on speech that’s similar to pre-emptively hiding content.

“One of the really important parts of that has to be transparency,” she said.

We are in the midst of a mobile tech revolution that promises to change the way we live, say industry experts at this week’s Mobile World Congress (MWC) in Barcelona, Spain, where the ‘Internet of Things’ and superfast 5G technologies are all the rage. But even the most basic mobile technology is changing lives in some of the world’s most remote parts.

The exhibit is a showcase of the latest technology — and a glimpse of what the future holds. And industry insiders at the MWC 2017 say  there is a lot more to come.

Pibo, for example, is a mobile-connected robot designed to help families connect and express their emotions in the digital age.  On the other hand, they could invest in a digital hang drum — a traditional instrument used in yoga, updated for the 21st century so it syncs with your smartphone.

U.S. technology giants AT&T and General Electric have come up with smart street lamps, with cameras, sensors and microphones connected to 4G mobile networks. Over three thousand are being installed in the western U.S. city of San Diego, California and will be used for traffic analysis.

But AT&T product manager Trey Winter, said the makers have bigger ambitions.

“You are going to be able to detect smart parking solutions, gunshot detections inside of a city infrastructure. Environmental features detecting weather, smog, pollution,” he said. “Really bringing to life the intelligence inside of the city.“

5G networks

Much of the buzz at this year’s show is around super-fast 5G networks — with faster download speeds and almost zero delay.

Roger Chen of CNET magazine explained that this means a “real-time connection.”

“The best example someone has given to me is a surgeon performing a surgery in one country with robotic hands in another country,” he added.

Apps offer solutions for Africa

Mobile technology is transforming the economies of many African countries, with smartphone apps ranging from herding cattle in Kenya and connecting dirty laundry to mobile washerwomen in Uganda.

Eneza, for one, uses basic mobile technology to offer access to a huge range of education. Two million students are signed up to its ‘virtual classroom‘ — and the better their grades, the more mobile airtime the parents receive.

The company’s chairman, Stephen Haggard said “they are able to access all the education they want for a subscription that’s about 10 U.S. cents per week.”

“That covers the full curriculum and will get them everything they need to do from around age eight to finishing school,” he said. “The reality in most of Africa is that mobile technology is actually the only way that you can reach huge numbers of people at low cost with any kind of content.”

A recent report by consultants McKinsey predicted that by 2025 half of sub-Saharan Africa’s billion strong population will have internet access, over two-thirds via smartphones.
