In the downstairs bathroom of a suburban home in a Northern California coastal town, tech blogger Robert Scoble derailed one of the most ambitious projects of one of the most powerful companies on Earth with a single photo.

Scoble's wife, Maryam, snapped the now-infamous picture in the couple's home in Half Moon Bay, about 30 miles northwest of Google's headquarters in Mountain View. Scoble is in the shower, wearing nothing but a psyched expression and Google Glass. The company had announced its smart eyewear a year earlier as part of an ambitious project led by Google co-founder Sergey Brin to reimagine how people interact with the world. Scoble was among Google's chosen few "Glass Explorers" invited to buy the $1,500 prototype.

The photo, thankfully, is cropped from the shoulders down.

"You thought I was kidding when I said I would never take them off," Scoble wrote when he posted the photo to his Google+ social network account on April 28, 2013.

Scoble soon became a premier spokesperson for the product. Outlets from the BBC to Bloomberg wanted him on their shows to explain how it worked. Glass, which connects to the Internet and overlays images and graphics over what a wearer sees with his non-computer eyes, was confounding the press. Wired hailed the augmented reality specs as something "straight out of Star Trek" while the New York Daily News described Glass as "cyborg glasses." CNET called it "Google on your face."

But Scoble's photo added another dimension: His nerd exuberance created a G-rated, consumer-tech version of a dick pic -- the kind of unsavory anatomical photo that's ruined politicians and private citizens -- that was shared around the world. The damage was done: He had helped make Glass uncool.

Even Google's chief executive, Larry Page, was riled. "Robert, I really didn't appreciate the shower photo," Page ribbed Scoble two weeks later when Scoble asked him a question during a public Q&A session at Google's annual I/O developer conference.

Scoble says he hasn't been invited back to the conference since.

"I was expecting it to get attention," he says of the photo. "But I wasn't expecting it to go viral."

Scoble's fanboy faux pas aside, the photo turned out to be only one of many obstacles for Google's experimental product -- one of the first major forays into wearable technology from a Silicon Valley giant. The device, with its built-in camera, became a lightning rod for controversy because some people feared their privacy was being violated. Movie theaters, bars and restaurants banned it, and some states debated whether to allow it while driving.

So where is Glass now? Back on the drawing board. Google paused the project in January, halting the Explorer program and discontinuing production of the costly prototype. It's reportedly working on a new model it hopes won't alienate so many people. Scoble -- who met with Glass's product lead Steve Lee less than a year ago -- believes the new version will be foldable, so you can take it off and easily store it when it's inappropriate to wear. He also believes it will have a red light to alert others when it's recording.

Google is also counting on Tony Fadell, the Apple alum known as the father of the iPod, to make Glass cool. Fadell, who also helped develop Apple's game-changing iPhone, joined Google in 2013 when the company bought his startup, Nest, which makes a next-generation thermostat, for more than $3 billion. Fadell's job will be to convince developers that Google's eyewear is the real deal for those looking for a more intimate relationship with their tech. If he can do that, Google just may be the software platform that powers the next wave of computing devices after smartphones, tablets and laptops. We're now talking about Internet-connected everything: cars, TVs, pens, blenders, baby toys and, of course, wearables.

If Fadell can't make Glass cool, no one can, say his fans. "I can't wait to see what Tony is going to do with it," says venture capitalist Marc Andreessen. His firm, Andreessen Horowitz, joined with Google Ventures and prominent VC rival Kleiner Perkins Caufield & Byers in 2013 to form the "Glass Collective" to invest in developers building apps for the device.

As for Scoble, Page and company owe a debt of gratitude to him and the unknown thousands of others who bravely tried to usher Glass into the real world (Google doesn't release Glass sales figures). "Explorer" was a fitting moniker for those early Glass wearers because unlike any other consumer who buys a new type of gadget -- say a phablet or an Apple Watch -- Google's evangelists entered unfamiliar terrain with sometimes hostile results, as detractors in some cases ripped the eyewear off their faces.

It's true exploration is about risk. Some of the world's most famous explorers -- Ferdinand Magellan, Ponce de Leon, Dr. David Livingstone -- died on their voyages. None of Google's Explorers became literal martyrs, but they did pay a price for being first in Google's brave new world. Fairly or unfairly, they're not likely to be honored as explorers. Instead, tech historians will remember them with the less than romantic sobriquet they're now collectively known as: Glassholes. Now Google is paying for its missteps with the Explorer program.

Google declined to comment.

Shiny Glass

Google, which unveiled Glass at its 2012 I/O conference in San Francisco, will host this year's conference starting May 28. The new version isn't likely to be ready by this year's conference, though some reports say the device will " be out soon." At I/O, Google is expected to tout updates to the Android mobile operating system, new initiatives around smart-home devices, and possibly even virtual reality efforts separate from the Glass project.

Three years ago, Glass made its debut at the developer fest on such a high. Four thousand feet above San Francisco's Moscone Convention Center, to be exact. Four skydivers jumped out of a zeppelin while wearing Glass for a Brin-led 2012 demo that introduced the device to the world. The press salivated over the spectacle.

Google initially let software developers and a small pool of others try the product, offering it to those they hoped would develop Glass apps. In February 2013, Google opened the Explorer program to more buyers. Would-be Explorers were asked what they would do with the product if they owned it. Those with the best responses were invited to buy Glass.

"Glass is still in the early stages, so we expect there will be some twists and turns along the way," Google wrote in a post when it expanded the Explorer program. "While we can't promise everything will be perfect, we can promise it will be exciting."

Of course, not every early buyer was a wannabe Glass evangelist. Some bought it because they were curious and had money to burn.

But there were others who bought into Google's bold explorer ethos. Justin Chung, a freelance illustrator in San Francisco, knew early on he wanted Glass so he could be on the "bleeding edge of technology." For his pitch to Google, he wrote that he'd use Glass to let people see what he was drawing, while drawing it. Google granted him the green light to buy Glass and gave him an invitation to a secret party in June where he could pick up the device.

Chung boarded a ferry to a discontinued naval base in nearby Alameda. The party, which had fewer than 100 attendees, was held on an old radar tower with sweeping views of San Francisco Bay. The newly minted Glass owners ate artisanal sandwiches, drank champagne and chatted about their new hardware. "They made you feel like you were part of what they were doing," says Chung.

Chung still wears his Glass almost every day while drawing, exercising, cooking or walking around San Francisco. He considers the Explorer program a very important "social experiment." "Centuries from now, we'll look back on it," says Chung. "You're putting cyborgs out in public, and we were out there trying to learn the right social protocol."

Other Explorers say the public needs to be patient, as people learn to live in a world with wearables. As for the nerdy aspect? That takes patience, too. "Remember when the first cell phone was released? It was big and clunky," says Ivan Yudhi, a software engineer from San Leandro, California. "It will take time."

Broken Glass

But the rest of the world wasn't willing to wait. The buzz wore off pretty quickly -- kind of like the adrenaline rush that fades after you've jumped out of a blimp. Eventually, "OK Glass" -- the command words that triggered the device's voice controls -- had become a dirty phrase. If the Explorers were Google's army, Glass was a faulty grenade.

One of the best-known Glass incidents involved an assault on a tech writer in a San Francisco bar in February 2014. Sarah Slocum was demonstrating Glass's video features to a friend at Molotov, a punk rock dive in the city's Lower Haight district. But some patrons became uncomfortable that she was recording. Slocum says a man ripped the Glass off her face, while his friends stole her phone and purse.

In another incident, Kyle Russell -- then a reporter for the website Business Insider -- had his Glass torn off while walking in San Francisco's Mission district.

Things got murkier for Glass. Police were giving people tickets for wearing the device while driving. At least six states, including New Jersey and Illinois, began drafting bills to make Glass illegal for drivers behind the wheel. The Motion Picture Association of America banned Glass from movie theaters.

Pop culture commentators had a field day. "Saturday Night Live" created a fictional tech correspondent named Randall Meeks, played by Fred Armisen, who fumbled through a Glass demonstration and eventually used it to watch online porn. Jerry Seinfeld last year wore Glass as Wired's "Guest Glasshole" for its June issue on social rules for the digital age. His publicist declined to have Seinfeld comment for this story because the comedian had only ever worn Glass for the Wired photo shoot.

Even those enthusiastic about wearable tech say they remain concerned about Glass. "I have some trepidation," says actor and author LeVar Burton, whose "Star Trek" character, Geordi La Forge, was famous for his futuristic eyewear. "My initial reaction to anybody when I see them wearing Glass is, are they recording?"

Anti-Glass campaigns also popped up. The UK-based "Stop the Cyborgs" effort created posters for bars and other public places saying "Google Glass is Banned On These Premises" and "No Surveillance Devices." You can print them from the group's website.

"It has become a bit of the poster child for some of those issues," Google's Astro Teller said in a November interview. Teller leads the experimental Google X lab, which developed Glass before the company handed the reins to Fadell. Teller thinks reaction to Glass is about a bigger issue: anxiety over an increasingly wired world. "That is the right conversation to have," he said. "There isn't an easy answer for that. But it's not really about Google Glass."

To guide Explorers in the right direction, Google created a 763-word etiquette guide in February 2014 for using the device in public. Among the dos and don'ts: Don't "be creepy or rude (aka a 'Glasshole')."

But internally at Google, Glass had already lost its luster. "When I first saw the word 'Glasshole' becoming more popular, that's when it dawned on me," says one former Google employee, who worked on business development for the Glass team. "That was the turning point."

There was frustration at the very top as well. "Sergey wasn't happy," the former employee says. "He had this vision. It wasn't being realized."

Another former Google employee, a Glass engineer who declined to be interviewed for this story, was blunt about why he didn't want to talk: "I've tried to put that project behind me."

After the Explorers

A lot has changed since Google stopped the Explorer program. One thing didn't: There are still thousands of people who own the $1,500 device. Some people continue to wear it. Others have tossed Glass into their drawers.

But in March 2013, it was a whole different story. That year, Glass was the hot topic at the South by Southwest (SXSW) conference in Austin, Texas, the annual confab for filmmakers, musicians and the technorati. Google held sessions and panels on how to develop for Glass. Austin was sprinkled with people who proudly sported the new device.

Two years later, not so much. I decided to wear Glass for a day at SXSW 2015 to get a sense of what it's like to be an Explorer today. ( Read more about that here.)

I wore them during an interview with Alex Winter, a documentary filmmaker and actor (he played Bill in the "Bill and Ted" movies.) Winter's film "Deep Web" premiered at the SXSW film festival and chronicles Silk Road, an online bazaar for drugs and other contraband, and its convicted founder Ross Ulbricht. Winter talks about the legitimate uses for anonymity software and the importance of fighting against constant surveillance.

After talking for a while, I noticed he was avoiding making eye contact with me. "No one's ever interviewed me while wearing Google Glass before," said Winter, laughing. "It's a little unsettling."

Walking around Austin, I drew many stares, but no one was blatantly rude. It didn't incite the same kind of passion the public felt only a year ago. Instead, it felt like a remnant from the not-too-distant past -- ironic because Glass was supposed to be a promise for the future.

Not only have things changed for Glass owners, but the Explorer program also changed how other companies approach marketing new wearable tech.

In October, Google led a $542 million funding round into Magic Leap, a secretive startup working on its own hi-tech glasses. Like Glass, when you put on Magic Leap's eyewear, you see a mélange of digital and real images. But Magic Leap promises that its graphics will look like they came out of a movie. Google put Sundar Pichai, the company's product czar and one of its most important executives, on Magic Leap's board of directors.

But it looks like Magic Leap has learned from Glass's unraveling. As of this writing, the company has only showed the product to two news outlets: The New York Times and the MIT Technology Review. When Scoble asked for a glimpse, the company turned him down. A Magic Leap employee told Scoble that the public relations team was "scared of you. We know you can change the direction of this product."

Glass incognito

Google has finally learned that lesson as well.

The idea behind Glass Explorers was simple enough: Get the product in the hands of early buyers, and see how they used it. But After Google shut down the Explorer program, Teller said that while it was a "great idea," it put too bright a spotlight on the Explorers.

"We allowed, and sometimes even encouraged, too much attention to the program," Teller said at SXSW this year. Google now wants to remain low key.

Google could have achieved that by hiring a group of 10 to 100 people to test the product for a year, says Tim Bajarin, president of market research firm Creative Strategies and an early Glass Explorer. That would have isolated problems to the testers instead of having them affect a broader consumer population. After Brin gave a talk about Glass at the TED conference in 2013, Bajarin said he met some of the Glass team members. "I don't even think they had an understanding of the role Glass should play in your life," he says. He describes Google's handling of Glass a "debacle."

It's now up to Fadell and a team of fashion industry veterans to resuscitate the project. It will be one of the hardest tasks Fadell has faced in his career. Can the former Apple hardware guru do it? Bajarin, a long-time Apple follower, is pessimistic. "No," he says flatly. Bajarin says the only shot Fadell has is to take development slowly, and try to keep Glass out of the public eye as he makes improvements.

Development of a new version is underway. Google is reportedly working with Intel to make the innards of the device. Luxottica, the Italian eyewear maker behind Ray-ban and Oakley, is supposedly making the frames. New job postings suggest Google wants to make Glass a family of devices. The company is looking for new members of the Glass team to build "smart eyewear and other related products." That's one area where Fadell's expertise may shine. Nest started out with one device, a Web-enabled thermostat, then expanded to include a smoke detector. Other smart-home devices are expected.

As for the Explorers, some still wear Glass proudly. Others, like Scoble, have changed their mind.

Earlier this month, I returned to the proverbial scene of the crime, the place where Scoble took the infamous shower photo. He donned his Glass -- black-trimmed with a 49ers sticker on the side frame -- for the first time in a year. He thinks the problem with Glass was that it created an unnatural division between him and the people he talks to. When he tells me this, he's not wearing the device.

The man who said he would never take it off tells me he was wrong to be such a big booster of Glass. "The novelty went away," he says. "Google abused their early adopters."

Hindsight is always 20/20.
