We finally started taking screen time seriously in 2018

Published

on

At the beginning of this year, I was using my iPhone to browse new titles on Amazon when I saw the cover of “How to Break Up With Your Phone” by Catherine Price. I downloaded it on Kindle because I genuinely wanted to reduce my smartphone use, but also because I thought it would be hilarious to read a book about breaking up with your smartphone on my smartphone (stupid, I know). Within a couple of chapters, however, I was motivated enough to download Moment, a screen time tracking app recommended by Price, and re-purchase the book in print.

Early in “How to Break Up With Your Phone,” Price invites her readers to take the Smartphone Compulsion Test, developed by David Greenfield, a psychiatry professor at the University of Connecticut who also founded the Center for Internet and Technology Addiction. The test has 15 questions, but I knew I was in trouble after answering the first five. Humbled by my very high score, which I am too embarrassed to disclose, I decided it was time to get serious about curtailing my smartphone usage.

Of the chapters in Price’s book, the one called “Putting the Dope in Dopamine” resonated with me the most. She writes that “phones and most apps are deliberately designed without ‘stopping cues’ to alert us when we’ve had enough—which is why it’s so easy to accidentally binge. On a certain level, we know that what we’re doing is making us feel gross. But instead of stopping, our brains decide the solution is to seek out more dopamine. We check our phones again. And again. And again.”

Gross was exactly how I felt. I bought my first iPhone in 2011 (and owned an iPod Touch before that). It was the first thing I looked at in the morning and the last thing I saw at night. I would claim it was because I wanted to check work stuff, but really I was on autopilot. Thinking about what I could have accomplished over the past eight years if I hadn’t been constantly attached to my smartphone made me feel queasy. I also wondered what it had done to my brain’s feedback loop. Just as sugar changes your palate, making you crave more and more sweets to feel sated, I was worried that the incremental doses of immediate gratification my phone doled out would diminish my ability to feel genuine joy and pleasure.

Price’s book was published in February, at the beginning of a year when it feels like tech companies finally started to treat excessive screen time as a liability (or at least do more than pay lip service to it). In addition to the introduction of Screen Time in iOS 12 and Android’s digital wellbeing tools, Facebook, Instagram and YouTube all launched new features that allow users to track time spent on their sites and apps.

Early this year, influential activist investors who hold Apple shares also called for the company to focus on how their devices impact kids. In a letter to Apple, hedge fund Jana Partners and California State Teachers’ Retirement System (CalSTRS) wrote “social media sites and applications for which the iPhone and iPad are a primary gateway are usually designed to be as addictive and time-consuming as possible, as many of their original creators have publicly acknowledged,” adding that “it is both unrealistic and a poor long-term business strategy to ask parents to fight this battle alone.”

The growing mound of research

Then in November, researchers at Penn State released an important new study that linked social media usage by adolescents to depression. Led by psychologist Melissa Hunt, the experimental study monitored 143 students with iPhones from the university for three weeks. The undergraduates were divided into two groups: one was instructed to limit their time on social media, including Facebook, Snapchat and Instagram, to just 10 minutes each app per day (their usage was confirmed by checking their phone’s iOS battery use screens). The other group continued using social media apps as they usually did. At the beginning of the study, a baseline was established with standard tests for depression, anxiety, social support and other issues, and each group continued to be assessed throughout the experiment.

The findings, published in the Journal of Social and Clinical Psychology, were striking. The researchers wrote that “the limited use group showed significant reductions in loneliness and depression over three weeks compared to the control group.”

Even the control group benefitted, despite not being given limits on their social media use. “Both groups showed significant decreases in anxiety and fear of missing out over baselines, suggesting a benefit of increased self-monitoring,” the study said. “Our findings strongly suggest that limiting social media use to approximately 30 minutes a day may lead to significant improvement in well-being.”

Other academic studies published this year added to the growing roster of evidence that smartphones and mobile apps can significantly harm your mental and physical wellbeing.

A group of researchers from Princeton, Dartmouth, the University of Texas at Austin, and Stanford published a study in the Journal of Experimental Social Psychology that found using smartphones to take photos and videos of an experience actually reduces the ability to form memories of it. Others warned against keeping smartphones in your bedroom or even on your desk while you work. Optical chemistry researchers at the University of Toledo found that blue light from digital devices can cause molecular changes in your retina, potentially speeding macular degeneration.

So over the past 12 months, I’ve certainly had plenty of motivation to reduce my screen time. In fact, every time I checked the news on my phone, there seemed to be yet another headline about the perils of smartphone use. I began using Moment to track my total screen time and how it was divided between apps. I took two of Moment’s in-app courses, “Phone Bootcamp” and “Bored and Brilliant.” I also used the app to set a daily time limit, turned on “tiny reminders,” or push notifications that tell you how much time you’ve spent on your phone so far throughout the day, and enabled the “Force Me Off When I’m Over” feature, which basically annoys you off your phone when you go over your daily allotment.

At first I managed to cut my screen time in half. I had thought some of the benefits, like a better attention span mentioned in Price’s book, were too good to be true. But I found my concentration really did improve significantly after just a week of limiting my smartphone use. I read more long-form articles, caught up on some TV shows, and finished knitting a sweater for my toddler. Most importantly, the nagging feeling I had at the end of each day about frittering all my time away diminished, and so I lived happily after, snug in the knowledge that I’m not squandering my life on memes, clickbait and makeup tutorials.

Just kidding.

Holding my iPod Touch in 2010, a year before I bought my first smartphone and back when I still had an attention span.

After a few weeks, my screen time started creeping up again. First I turned off Moment’s “Force Me Off” feature, because my apartment doesn’t have a landline and I needed to be able to check texts from my husband. I kept the tiny reminders, but those became easier and easier to ignore. But even as I mindlessly scrolled through Instagram or Reddit, I felt the existentialist dread of knowing that I was misusing the best years of my life. With all that at stake, why is limiting screen time so hard?

I wish I knew how to quit you, small device

I decided to talk to the CEO of Moment, Tim Kendall, for some insight. Founded in 2014 by UI designer and iOS developer Kevin Holesh, Moment recently launched an Android version, too. It’s one of the best known of a genre that includes Forest, Freedom, Space, Off the Grid, AntiSocial and App Detox, all dedicated to reducing screen time (or at least encouraging more mindful smartphone use).

Kendall told me that I’m not alone. Moment has 7 million users and “over the last four years, you can see that average usage goes up every year,” he says. By looking at overall data, Moment’s team can tell that its tools and courses do help people reduce their screen time, but that often it starts creeping up again. Combating that with new features is one of the company’s main goals for next year.

“We’re spending a lot of time investing in R&D to figure out how to help people who fall into that category. They did Phone Bootcamp, saw nice results, saw benefits, but they just weren’t able to figure out how to do it sustainably,” says Kendall. Moment already releases new courses regularly (recent topics have included sleep, attention span, and family time) and recently began offering them on a subscription basis.

“It’s habit formation and sustained behavior change that is really hard,” says Kendall, who previously held positions as president at Pinterest and Facebook’s director of monetization. But he’s optimistic. “It’s tractable. People can do it. I think the rewards are really significant. We aren’t stopping with the courses. We are exploring a lot of different ways to help people.”

As Jana Partners and CalSTRS noted in their letter, a particularly important issue is the impact of excessive smartphone use on the first generation of teenagers and young adults to have constant access to the devices. Kendall notes that suicide rates among teenagers have increased dramatically over the past two decades. Though research hasn’t explicitly linked time spent online to suicide, the link between screen time and depression has been noted many times already, as in the Penn State study.

But there is hope. Kendall says that the Moment Coach feature, which delivers short, daily exercises to reduce smartphone use, seems to be particularly effective among millennials, the generation most stereotypically associated with being pathologically attached to their phones. “It seems that 20- and 30-somethings have an easier time internalizing the coach and therefore reducing their usage than 40- and 50-somethings,” he says.

Kendall stresses that Moment does not see smartphone use as an all-or-nothing proposition. Instead, he believes that people should replace brain junk food, like social media apps, with things like online language courses or meditation apps. “I really do think the phone used deliberately is one of the most wonderful things you have,” he says.

I’ve tried to limit most of my smartphone usage to apps like Kindle, but the best solution has been to find offline alternatives to keep myself distracted. For example, I’ve been teaching myself new knitting and crochet techniques, because I can’t do either while holding my phone (though I do listen to podcasts and audiobooks). It also gives me a tactile way to measure the time I spend off my phone because the hours I cut off my screen time correlate to the number of rows I complete on a project. To limit my usage to specific apps, I rely on iOS Screen Time. It’s really easy to just tap “Ignore Limit,” however, so I also continue to depend on several of Moment’s features.

While several third-party screen time tracking app developers have recently found themselves under more scrutiny by Apple, Kendall says the launch of Screen Time hasn’t significantly impacted Moment’s business or sign ups. The launch of their Android version also opens up a significant new market (Android also enables Moment to add new features that aren’t possible on iOS, including only allowing access to certain apps during set times).

The short-term impact of iOS Screen Time has “been neutral, but I think in the long-term it’s really going to help,” Kendall says. “I think in the long-term it’s going to help with awareness. If I were to use a diet metaphor, I think Apple has built a terrific calorie counter and scale, but unfortunately they have not given people nutritional guidelines or a regimen. If you talk to any behavioral economist, not withstanding all that’s been said about the quantified self, numbers don’t really motivate people.”

Guilting also doesn’t work, at least not for the long-term, so Moment tries to take “a compassionate voice,” he adds. “That’s part of our brand and company and ethos. We don’t think we’ll be very helpful if people feel judged when we use our product. They need to feel cared for and supported, and know that the goal is not perfection, it’s gradual change.”

Many smartphone users are probably in my situation: alarmed by their screen time stats, unhappy about the time they waste, but also finding it hard to quit their devices. We don’t just use our smartphones to distract ourselves or get a quick dopamine rush with social media likes. We use it to manage our workload, keep in touch with friends, plan our days, read books, look up recipes, and find fun places to go. I’ve often thought about buying a Yondr bag or asking my husband to hide my phone from me, but I know that ultimately won’t help.

As cheesy as it sounds, the impetus for change must come from within. No amount of academic research, screen time apps, or analytics can make up for that.

One thing I tell myself is that unless developers find more ways to force us to change our behavior or another major paradigm shift occurs in mobile communications, my relationship with my smartphone will move in cycles. Sometimes I’ll be happy with my usage, then I’ll lapse, then I’ll take another Moment course or try another screen time app, and hopefully get back on track. In 2018, however, the conversation around screen time finally gained some desperately needed urgency (and in the meantime, I’ve actually completed some knitting projects instead of just thumbing my way through #knittersofinstagram).

Biden’s executive order limits government’s use of commercial spyware

Published

on

President Joe Biden on Monday signed an executive order barring many uses by the federal government of commercial spyware, which has been increasingly used by other countries in recent years to surveil dissidents, journalists, and politicians.

The signing of the executive order came as administration officials told journalists that roughly 50 US government personnel in at least 10 countries had been infected or targeted by such spyware, a larger number than previously known. The officials didn’t elaborate.

Commercial spyware is sold by a host of companies, with the best known being NSO Group of Israel. The company sells a hacking tool known as Pegasus that can surreptitiously compromise both iPhones and Android devices using “clickless” exploits, meaning they require no user interaction. By sending a text or ringing the device, Pegasus can install spying software that steals contacts, messages, geo locations, and more, even when the text or call isn’t answered. Other companies selling commercial spyware include Cytrox, Candiru, and Paragon.
While NSO describes Pegasus as a “lawful intercept” tool that’s sold only to legitimate law-enforcement agencies to investigate crime and terrorism. Mexico, India, Saudi Arabia, the United Arab Emerates, Morocco, and other countries have been caught deploying it against political dissidents, journalists, and other citizens that aren’t accused of any crimes. In November 2021, the Biden administration restricted the export, re-export, and in-country transfer of products from NSO and three other companies in Israel, Russia, and Singapore.

Monday’s executive order goes further by barring federal agencies, including those engaged in law enforcement, defense, or intelligence activities, from “operationally using” commercial spyware.

“The proliferation of commercial spyware poses distinct and growing counterintelligence and security risks to the United States, including to the safety and security of US Government personnel and their families,” a fact sheet published by the White House said. “US Government personnel overseas have been targeted by commercial spyware, and untrustworthy commercial vendors and tools can present significant risks to the security and integrity of US Government information and information systems.”

White House officials aren’t naming the specific spyware that’s barred, but using the term commercial spyware strongly implies it includes tools sold by NSO, Cytrox, Candiru, and others. Criteria for tools falling under the order include if:

  • they’re abused by a foreign government in an attempt to access the device of a US citizen
  • a foreign actor deploys them against activists or dissidents in an attempt to intimidate or curb dissent or opposition or squelch expressions of free speech
  • they’re supplied to governments for which there are credible reports that they engage in systematic acts of political repression.

The officials declined to say if US law enforcement and intelligence agencies currently use commercial spyware. Last year, the FBI confirmed a New York Times report that the bureau had bought NSO Group’s Pegasus tool for product testing and evaluation but said they weren’t used for operational purposes or to support any investigation. The US Drug Enforcement Agency, the NYT has also reported, deployed a surveillance tool called Graphite for use in counternarcotics operations.

The power of AI compels you to believe this fake image of Pope in a puffy coat

Published

Over the weekend, an AI-generated image of Pope Francis wearing a puffy white coat went viral on Twitter, and apparently many people believed it was a real image. Since then, the puffy pontiff has inspired commentary on the deceptive nature of AI-generated images, which are now nearly photorealistic.

The pope image, created using Midjourney v5 (an AI image synthesis model), first appeared in a tweet by a user named Leon (@skyferrori) on Saturday and quickly began circulating as part of other meme tweets featuring similar images as well, including one that humorously speculates about a pope “lifestyle brand.”

Not long after, Twitter attached a reader-added context warning to the tweet that reads, “This is an AI-generated image of Pope Francis. It is not a genuine photo.

As noted in our piece on last week’s AI-generated Donald Trump arrest photos, Twitter guidelines state that users “may not deceptively share synthetic or manipulated media that are likely to cause harm.” Although in this case, the line between harm and parody might be a fuzzy one.

How do we know the image is fake? Aside from a Reddit post containing alternative images of the Pope from the person that likely made it, The Verge breaks down the evidence fairly well in a piece analyzing the impact of the false image. For example, if you zoom in on details, you’ll see telltale signs of image synthesis in warped details like the pope’s crucifix necklace, the crooked shadow of his glasses, and whatever he is carrying in his hand (a cup?).

But still, upon a quick glance, the false photo (“fauxto”?) looks fairly realistic. And as The Verge notes, a stylish image of Pope Francis plays into our beliefs about the papacy, which often involves wild non-fake imagery—although Pope Francis is known for his “humble” outfits.

A Midjourney journey

The image service used to create the fake photo, Midjourney, debuted last year. Along with DALL-E and Stable Diffusion, it’s one of three major image synthesis models that have become popular online. All three allow users to generate novel images using only text descriptions called “prompts.”

Our experiments with

Midjourney

In this case, the prompt used to create the puffy pope photo might have been as simple as “Pope Francis in a puffy white coat” because Midjourney has made huge leaps in photorealism recently, rendering complex scenes full of details from relatively simple prompts.

What this almost effortless capability to fake photos means for the future of media is still uncertain, but as we’ve speculated before, due to image synthesis, we may never be able to believe what we see online again.

Hobbyist builds ChatGPT client for MS-DOS

Published

On Sunday, Singapore-based retrocomputing enthusiast Yeo Kheng Meng released a ChatGPT client for MS-DOS that can run on a 4.77 MHz IBM PC from 1981, providing a unique way to converse with the popular OpenAI language model.

Vintage computer development projects come naturally to Yeo, who created a Slack client for Windows 3.1 back in 2019. “I thought to try something different this time and develop for an even older platform as a challenge,” he writes on his blog. In this case, he turned his attention to MS-DOS, a text-only operating system first released in 1981, and ChatGPT, an AI-powered large language model (LLM) released by OpenAI in November.

As a conversational AI model, ChatGPT draws on knowledge scraped from the Internet to answer questions and generate text. Thanks to an API that launched his month, anyone with the programming chops can interface ChatGPT with their own custom application.

Thanks to his new app, which can run on MS-DOS, Yeo can use a vintage IBM PC-compatible computer to chat with ChatGPT over the Internet. It’s a similar back-and-forth conversation as the traditional ChatGPT web interface, albeit as a text-only, full-screen application running on the antique machine.

Development challenges

MS-DOS posed a particularly challenging platform for a ChatGPT client, lacking native networking abilities. In addition, Yeo targeted a computer with very limited processing power: a 1984 IBM 5155 Portable PC, which includes an Intel 8088 4.77 MHz CPU, 640KB conventional memory, CGA ISA graphics, and MS-DOS 6.22.

To create the client, Yeo used Open Watcom C/C++, a modern compiler running on Windows 11 that can target 16-bit DOS platforms. For testing purposes, he used a VirtualBox virtual machine running DOS 6.22 to streamline the development process, then he transferred the compiled binary to the target IBM DOS PC for testing.

To handle networking on the IBM PC, Yeo needed to weave his way through several layers. First, Yeo utilized a “Packet Driver API” standard invented in 1983. He integrated the open source MTCP library by Michael B. Brutman into the application to communicate with the Packet Driver, enabling networking capabilities for the client.

For the ChatGPT API, Yeo used OpenAI’s Chat Completion API, constructing the POST request (and parsing the JSON-formatted response) manually in C.

However, Yeo hit a major snag: the ChatGPT APIs require encrypted HTTPS connections. Since there are no native HTTPS libraries for MS-DOS, Yeo had to create an HTTP-to-HTTPS proxy that can run on a modern computer and translate the requests and responses between the MS-DOS client and ChatGPT’s secure API, acting as a transparent middleman in the communication process.

Yeo says that reading and writing input to the console presented another challenge due to the single-threaded nature of DOS applications. He devised a method to check and receive keypresses without pausing the program using the MTCP page and online samples as a reference.

In the end, the client works better than Yeo expected, and he looks forward to more retro challenges in the future: “After experiencing this, I will definitely be writing more retro-software in future,” he writes in a blog post that describes his development process in more detail.

Yeo has released his code (called “doschgpt”) on GitHub if others want to run it themselves—or perhaps improve or extend the code in the future. With a little creativity, the latest tech in AI language models need not be limited to cutting-edge machines.
