After 'AI-First' Promise, Duolingo CEO Admits 'I Did Not Expect the Blowback' (ft.com) 46

Last month, Duolingo CEO Luis von Ahn "shared on LinkedIn an email he had sent to all staff announcing Duolingo was going 'AI-first'," remembers the Financial Times.

"I did not expect the amount of blowback," he admits.... He attributes this anger to a general "anxiety" about technology replacing jobs. "I should have been more clear to the external world," he reflects on a video call from his office in Pittsburgh. "Every tech company is doing similar things [but] we were open about it...."

Since the furore, von Ahn has reassured customers that AI is not going to replace the company's workforce. There will be a "very small number of hourly contractors who are doing repetitive tasks that we no longer need", he says. "Many of these people are probably going to be offered contractor jobs for other stuff." Duolingo is still recruiting if it is satisfied the role cannot be automated. Graduates who make up half the people it hires every year "come with a different mindset" because they are using AI at university.

The thrust of the AI-first strategy, the 46-year-old says, is overhauling work processes... He wants staff to explore whether their tasks "can be entirely done by AI or with the help of AI. It's just a mind shift that people first try AI. It may be that AI doesn't actually solve the problem you're trying to solve.....that's fine." The aim is to automate repetitive tasks to free up time for more creative or strategic work.

Examples where it is making a difference include technology and illustration. Engineers will spend less time writing code. "Some of it they'll need to but we want it to be mediated by AI," von Ahn says... Similarly, designers will have more of a supervisory role, with AI helping to create artwork that fits Duolingo's "very specific style". "You no longer do the details and are more of a creative director. For the vast majority of jobs, this is what's going to happen...." [S]ocietal implications for AI, such as the ethics of stealing creators' copyright, are "a real concern". "A lot of times you don't even know how [the large language model] was trained. We should be careful." When it comes to artwork, he says Duolingo is "ensuring that the entirety of the model is trained just with our own illustrations".

A California Boy Was Kidnapped from a Park in 1951. He's Just Been Found Alive (sfgate.com) 132

An anonymous reader shared this story from SFGate: A boy who was kidnapped from an Oakland playground in 1951 has been found alive on the East Coast, a remarkable resolution to a mystery that has haunted his family for over half a century.

On February 21, 1951, 6-year-old Luis Armando Albino was playing with his older brother Roger at Jefferson Square Park. The boys had recently immigrated with their mother and four other siblings from Puerto Rico... That afternoon, Luis and 10-year-old Roger walked down the block from their home at 730 Brush Street to play in the park. They were approached by a woman in her 30s, wearing a green bandana over her hair, who began chatting with Luis in Spanish. She promised she would buy him candy if he came along with her, and little Luis agreed to join her. Wary, Roger trailed the pair for a while before returning home to alert an adult to the strange encounter. Oakland police were called by frantic family members and a search was immediately launched...

Antonia [the boy's mother] was convinced her son was alive. "She came once a week, then once a month, then at least once a year, to see the shake of the head, to have the answer 'no' translated for her although she could read it in the officers' faces," the Oakland Tribune wrote in 1966...

Decades passed.

In 2020, Luis' niece, Alida Alequin, took a DNA test on a whim, the Mercury News reported. The service returned several possible family members to the Oakland woman. One of them was a man who Alequin had never met. After some internet sleuthing, she began to suspect this man might be the missing uncle she'd heard so much about. She reached out to the man but didn't hear back.

Earlier this year, Alequin tried again. Armed with photos, she took her evidence to the Oakland Police Department's missing persons unit. In short order, the FBI and California Department of Justice were also investigating Alequin's lead. They discovered the man was living on the East Coast, had worked as a firefighter and served two tours in Vietnam with the Marine Corps. This week, the Mercury News first reported that a DNA test confirmed what Alequin suspected: This was Luis Albino.

In June, Luis flew to California to reunite with his family, among them his devoted brother Roger... For over 70 years, he lived on the East Coast believing he was the son of another couple....

When Luis met Alequin for the first time this summer, he held her in an embrace. "Thank you," he said, "for finding me."

Third Monolith Reappears, Fourth and Fifth Monoliths Discovered (insider.com) 103

"People taking a stroll on Sunday morning stumbled upon another mysterious monolith," reports Insider.com. "This one was found in a northern province of the Netherlands." The monolith was covered in ice and surrounded by a small pool of water, according to local reports. The hikers told the Dutch paper Algemeen Dagblad that they're not sure how the monolith got there. They said they found no footprints around it that would indicate someone placed it there intentionally.
And that monolith that disappeared in Atascadero, California has not-so-mysteriously re-appeared, as a group of three local artists takes credit for both creating the original and for successfully retrieving it to restore it to its former glory. "After learning of the second monolith, Travis Kenney had a thought," writes the relationship site Your Tango. "There were three monoliths in 2001: A Space Odyssey. Why not build the third themselves and make the triad complete...?"

"It was meant to be something fun, a change of pace from the kind of conversations 2020 has been plagued with — so much negativity and separation among the people in our country."
All the thanks these men really needed was delivered in the positive energy that quickly took hold of their home town. The presence of this now internationally followed mysterious object brought with it an uplifting local pride, as well as a sense of childlike wonder... The monolith's creators quietly made the hike back up to observe people's reactions throughout the day. When they arrived at the top each time, they found themselves soaking in the glow of the many smiles they encountered on faces of visitors. some of whom drove for hours to see the shining obelisk for themselves...

While you may think of these monoliths as another square on your 2020 bingo card, it's worth noting that the purpose of the monoliths in 2001: A Space Odyssey was to further the advancement of intelligent life. Cynics can say that sounds cheesy, but for the sake of full disclosure, I know McKenzie personally and can affirm without doubt or irony that they wanted nothing more than to offer their fellow humans some joyful light in these dark times.

"There was no esoteric agenda," said McKenzie.

"Our topline," added Jared Riddle, "Let's get outside and laugh."

70 miles away yet-another monolith "was discovered by campers on Saturday in San Luis Obispo County in Los Padres National Forest," reports a California newspaper. "We were super happy that someone/group went to all that work," Matt Carver wrote in a Facebook message to The Tribune. "It really did make our day to find it! I think we had huge smiles on our faces for the rest of the ride home."

The second monolith resembles the monolith in Atascadero, but the structure's top features "CAUTION" written in red and a picture of a UFO beaming in a human.

But wait! Insider.com reports that another mysterious monolith has appeared in Pittsburgh — "intentionally placed outside a candy shop by an owner who was trying to attract attention to his small business." Christopher Beers, owner of Grandpa Joe's Candy Shop, asked a friend to make the 10-foot-tall structure and placed it outside his store as a marketing ploy.

Grandpa Joe's Candy Shop shared the news using a 30-minute video on Facebook. In a Facebook post on Friday, the shop said: "Come see the Monolith before it mysteriously disappears!"

Within one day someone did in fact steal the monolith, reports the Pittsburgh Tribune-Review. But Grandpa Joe's owner Beers whipped up another one to replace it. "This one is much heavier and bolted into the ground. That's not a challenge. That's just a statement." Beers said he didn't report the theft to police because they have more important things to deal with... "That's not the story," Beers said of the theft. "The story is I built something fun and made people laugh and we put Pittsburgh on the map. I'm not worried about whoever took it."

Beers said the new monolith will stay up for a couple a days before "it'll mysteriously disappear just like all the others."

Business Insider reports that monolith jokes have now also appeared in tweets from a wide variety of brands, including Walmart, Southwest Airlines, Ocean Spray, McDonald's, Steak-umm, and MoonPie.

And meanwhile, the headline at one Denver news site reports that "Monolith mania comes to Colorado as local businesses report structures 'appearing' outside shops," citing the arrival of a monolith outside McDevitt Taco Supply and on the patio of Morrison Holiday Bar.

Scientists Create DNA-Based Exploit of a Computer System (technologyreview.com) 43

Archeron writes: It seems that scientists at University of Washington in Seattle have managed to encode malware into genomic data, allowing them to gain full access to a computer being used to analyze the data. While this may be a highly contrived attack scenario, it does ask the question whether we pay sufficient attention to data-driven exploits, especially where the data is instrument-derived. What other systems could be vulnerable to a tampered raw data source? Perhaps audio and RF analysis systems? MIT Technology Review reports: "To carry out the hack, researchers led by Tadayoshi Kohno and Luis Ceze encoded malicious software in a short stretch of DNA they purchased online. They then used it to gain 'full control' over a computer that tried to process the genetic data after it was read by a DNA sequencing machine. The researchers warn that hackers could one day use faked blood or spit samples to gain access to university computers, steal information from police forensics labs, or infect genome files shared by scientists. To make the malware, the team translated a simple computer command into a short stretch of 176 DNA letters, denoted as A, G, C, and T. After ordering copies of the DNA from a vendor for $89, they fed the strands to a sequencing machine, which read off the gene letters, storing them as binary digits, 0s and 1s. Yaniv Erlich, a geneticist and programmer who is chief scientific officer of MyHertige.com, a genealogy website, says the attack took advantage of a spill-over effect, when data that exceeds a storage buffer can be interpreted as a computer command. In this case, the command contacted a server controlled by Kohno's team, from which they took control of a computer in their lab they were using to analyze the DNA file."
