Remember Juicero, Google Glass, iTunes Ping, Fire Phone?

Like most teen years, the past decade in technology started out someplace relatively innocent before growing moody, dark and disillusioned.

In 2010, we were excited about new iPhones and finding old friends on Facebook, not fretting about our digital privacy or social media’s threat to democracy. Now we are wondering how to rein in the largest companies in the world and reckoning with wanting innovation to be both fast and responsible.

Over the past 10 years, new technology has changed how we communicate, date, work, get around and pass time. But for every hit, there have been high-profile disappointments and delays. That includes overpriced gadgets for making juice, face computers, promises of taking a vacation in space and companies claiming to be saving the world.

The failures served a purpose, acting as reality checks for the technology industry and the people who fund, regulate or consume its products. Tech companies spent the last decade first trying to grasp, then distance themselves from, their impact on society. Facebook’s famously decommissioned “move fast and break things” motto sounded plucky in 2010 and laughably misguided in 2019, when the company had, in fact, broken things.

It was a decade when billions of dollars were thrown at tech companies, and yet many of the promises those companies made never materialized, blew up in our faces or were indefinitely delayed. And while tech failures are nothing new, taken together they brought the innovation industrial complex closer to earth and made us all a bit more realistic — if less fun.

Like proper adults.

The benevolent, worldsaving tech company

“Don’t be evil” read Google’s famous motto, which sat atop its code of conduct until 2018, when it was quietly demoted to the last line.

At the beginning of the decade, that is exactly how many of the largest tech companies and CEOs marketed themselves. Their products were not only going to make daily life easier or more enjoyable, but they also would make the entire world better — even if their business models depended on ads and your personal data.

“Facebook was not originally founded to be a company. We’ve always cared primarily about our social mission,” chief executive

Mark Zuckerberg said in a 2012 letter, just before the company’s initial public offering. He outlined lofty visions going forward, including that Facebook would create a more “honest and transparent dialog” about government through accountability.

Instead, the decade turned toward disinformation, and hate speech spread on social media. Facebook, Twitter and Google’s YouTube were used to spread disinformation ahead of the 2016 U.S. election, while Google briefly worked on a search engine for China that would censor content. Companies profited off mountains of user data they collected but failed to protect, as major data breaches hit Equifax, Yahoo and others.

Face computers

Google co-founder Sergey Brin debuted Google Glass in 2012 by wearing a prototype of the smart glasses onstage. Its real PR outing came later that year when skydivers live-streamed their jump out of a blimp above San Francisco during a Google developer conference.

By showing information in front of the face instead of on a phone, Google said, the $1,500 Glass would allow people to interact more with the world around them. Instead, its legacy has been questions about our right to privacy from recording devices, the word “glasshole,” and at least one bar fight. The company stopped selling Glass to consumers in 2015 and shifted it to a workplace product, targeting everyone from factory workers to doctors.

Google was not alone. Microsoft made HoloLens, a technically ambitious piece of eyewear that looked like round steampunk goggles and used augmented reality. Facebook bought virtual-reality goggle maker Oculus for $2 billion and heavily invested in and promoted it as a gaming and entertainment device (and the future of social media). Magic Leap, another augmented reality headset promising immersive and mind-blowing entertainment, managed to raise $2.6 billion and only release one $2,295 developer product.

A more efficient way of eating

Juice. Colorful, thirst-quenching, packed with vitamins, on-demand juice. It seemed an unlikely thing for Silicon Valley to try to disrupt. But in the 2010s, entrepreneurs’ impatience with preparing and even consuming the calories necessary to survive led to a number of eating innovations.

One of the decade’s most memorable tech failures asked the question: What if you spent $699 for an elaborate machine that squeezed juice from proprietary bags of fruit and vegetable pulp for you? The answer, discovered by intrepid Bloomberg journalists in 2017, is that you could squeeze those packets with your hands instead of overpaying for a machine. That machine was Juicero, and it raised $120 million in funding before shutting down just five months later.

Non-Facebook social networks

Remember Path? Color? Yik Yak, Meerkat and Google Buzz? And iTunes Ping, Apple’s short-lived attempt at making its music hub social? Start-ups and the tech giants alike launched social products over the past decade, but few succeeded.

In 2010 there was Google Buzz, which was quickly replaced by Google+ in 2011. The service struggled to attract users and experienced privacy issues, such as a bug exposing more than 52 million people’s data. It was finally declared dead this year, though some of its best features live on in Google Photos.

Vine burned bright for too short a time before being closed in 2016 by Twitter, which had bought the company for a reported $30 million in 2012.

A crowdfunding, DIY revolution

For a short time, it looked as though the next generation of gadgets would come from outside the usual Silicon Valley idea factories. They would be dreamed up by passionate hobbyists, prototyped on 3-D printers and funded by fans instead of venture capitalists (though still manufactured in Shenzhen, China). Despite some notable successes — Oculus, Peloton, Boosted Boards — it turns out getting an idea from your cocktail napkin to market is pretty tough.

Notable failures include the disappointing Coolest Cooler, which featured both Bluetooth and a blender and raised more than $13 million on Kickstarter in 2014. It failed to deliver products to a third of its backers; many that shipped didn’t work. Others never materialized, such as iBackPack, which was supposed to produce a WiFi hotspot. The people behind it raised more than $800,000 and were accused by the Federal Trade Commission of using those funds to buy bitcoin and pay off credit cards.

Consumer 3-D printers also failed to live up to the hype. We were supposed to have a printer in every home, spitting out replacement LEGOs and screws, art projects, and even food. The high cost of the devices and the skills needed to use them could not compete with overnight shipping.

Drones dropping deliveries

“Could it be, you know, four, five years? I think so. It will work, and it will happen, and it’s gonna be a lot of fun,” Amazon Chief Executive Jeff Bezos said.

The year was 2013, and Bezos was on “60 Minutes” to unveil the next big thing in package delivery: drones. He said that within that time frame, quadcopters would be able to drop packages from warehouses at customers’ doors within 30 minutes. (Bezos owns The Washington Post.)

But as of the end of the decade, Amazon packages are still being delivered by humans. In fact, Amazon announced in 2018 that it was adding 20,000 delivery vans via third-party delivery partners to its ground fleet.

Vaping to fix smoking

It was supposed to be safer than smoking and a way to quit nicotine altogether. While vaping has indeed caught on, its biggest selling point has blown up in recent years. Eight deaths and more than 2,500 cases of lung-related illnesses have been linked to vaping in the United States.

Critics say fun-sounding flavors and colorful devices, most notably from the company Juul, have made vaping wildly popular with teenagers — one in four high schoolers vapes, according to the U.S. Centers for Disease Control and Prevention. Now the FDA and lawmakers are investigating vaping companies.

Amazon’s big phone play

Apple and Google have direct access to billions of people with their smartphone operating systems and hardware — 2.5 billion devices run Google’s Android operating system, and 900 million iPhones are in use.

One company noticeably absent from our pockets is Amazon, but not for lack of trying. After several years of stealth development, Amazon announced its Fire Phone in 2014. The smartphone did not look like much, started at $199, ran on a customized version of Android and was available only on AT&T. Amazon reported $83 million of unused inventory in late 2014, and it discontinued the Fire Phone a year after its introduction.

Tourists in space

It is no secret that bigname billionaires love space. Despite their passion, the three boldest aspiring space barons have made and missed deadlines for sending people into space this decade.

Richard Branson said Virgin Galactic would fly tourists into space by 2020, but its last test mission was two test pilots and a crew member at the start of last year. Bezos said at an Air Force Association conference in late 2018 that Blue Origin would send a test flight into the upper atmosphere with people on board this year, but the most recent test flight, on Dec. 11, contained no humans. In 2017, Elon Musk announced that SpaceX had taken deposits to fly two passengers around the moon in 2018. That flight did not take place. He has the whole next decade to hit a different goal, set in 2011: sending someone to Mars by 2031.
