Today the iconic Bitcoin white paper "celebrates thirteen years of financial disruption," notes Cointelegraph, "after being first published on Oct. 31, 2008, by an anonymous person or entity named Satoshi Nakamoto." (Here's a 2013 story from Slashdot about version 0.3.)

Cointelegraph writes: The white paper, titled Bitcoin: A Peer-to-Peer Electronic Cash System, foresaw the need for a peer-to-peer online payment system that is self-governing, secure and limited in quantity. The Bitcoin network was launched on Jan. 3, 2009, with each Bitcoin priced at $0.0008.... Today, Bitcoin maintains a stable trading value well above $60k after experiencing a gradual appreciation of 7,749,999,900% since its launch.
Cointelegraph celebrated the anniversary by embedding a video of the original bitcoin white paper being read by comedian Gilbert Gottfried — but they weren't the only ones. Entrepreneur/investor Anthony Pompliano celebrated with the return of what he describes as a decentralized pizzeria" named Bitcoin pizza. (An interactive online map shows participating locations around the U.S.A. where pizzas can be ordered with cash or with 0.0003 BTC — either through the web site or through the Uber Eats app.)

"If you want to pay for your pizza in bitcoin, I will gladly take your bitcoin," Pompliano says in a video posted to Twitter. "I don't think that you should use your bitcoin to buy the pizza — but we now accept bitcoin." The five available topping combos even have bitcoin-themed names like "No Keys, No Cheese" and "Satoshi's Favorite" — and the pizzas are all delivered in a special commemorative bitcoin-themed pizza box. "Every single dollar that I make from this, I donate to bitcoin developers," Pompliano explains in the video. "I make zero dollars from Bitcoin Pizza."

"And we're going to keep building this until eventually we are the single largest independent pizza chain in the United States. And then after we become the single largest independent pizza chain in the United States, we're going to turn around, and then we're going to go international."

"What if we told you there was a hamster who has been trading cryptocurrencies since June — and recently was doing better than Warren Buffett and the S&P 500?" asks NPR: Meet Mr. Goxx, a hamster who works out of what is possibly the most high-tech hamster cage in existence.

It's designed so that when Mr. Goxx runs on the hamster wheel, he can select among dozens of cryptocurrencies. Then, deciding between two tunnels, he chooses whether to buy or sell. According to the Twitch account for the hamster, his decision is sent over to a real trading platform — and yes, real money is involved.
Last Monday, after 100 days the hamster's portfolio was up 48%, reports one site, "before Bitcoin tumbled, which brought the rest of the crypto market down with it." But the hamster's portfolio is still up nearly 30% since he started trading in June, the article points out, "outperforming Bitcoin, the S&P 500, and even Warren Buffett's Berkshire Hathaway."

The hamster's business partner adds that profits aren't yet enough to cover the initial investment on Mr. Goxx's cage. And there's other issues...

"Since Mr. Goxx is an honorable business rodent, he must calculate with about 35% tax being subtracted on all his returns, so there is still some work left before he can really talk about making money."

The 31st annual Ig Nobel Prizes were awarded at a special ceremony on September 9th, announced the magazine responsible for the event, the Annals of Improbable Research.

But this week they made another announcement. "YouTube's notorious takedown algorithms are blocking the video of the 2021 Ig Nobel Prize ceremony." We have so far been unable to find a human at YouTube who can fix that. We recommend that you watch the identical recording on Vimeo.

Here's what triggered this: The ceremony includes bits of a recording (of tenor John McCormack singing "Funiculi, Funicula") made in the year 1914.

YouTube's takedown algorithm claims that the following corporations all own the copyright to that audio recording that was MADE IN THE YEAR 1914: "SME, INgrooves (on behalf of Emerald); Wise Music Group, BMG Rights Management (US), LLC, UMPG Publishing, PEDL, Kobalt Music Publishing, Warner Chappell, Sony ATV Publishing, and 1 Music Rights Societies"

Ideas from 4chan (including its paranormal section) have percolated into the "dead internet" theory, writes the Atlantic, with a seminal post on another forum by "IlluminatiPirate" now arguing that the internet is almost entirely overrun by artificial intelligence: Like lots of other online conspiracy theories, the audience for this one is growing because of discussion led by a mix of true believers, sarcastic trolls, and idly curious lovers of chitchat... Peppered with casually offensive language, the post suggests that the internet died in 2016 or early 2017, and that now it is "empty and devoid of people," as well as "entirely sterile." Much of the "supposedly human-produced content" you see online was actually created using AI, IlluminatiPirate claims, and was propagated by bots, possibly aided by a group of "influencers" on the payroll of various corporations that are in cahoots with the government. The conspiring group's intention is, of course, to control our thoughts and get us to purchase stuff... He argues that all modern entertainment is generated and recommended by an algorithm; gestures at the existence of deepfakes, which suggest that anything at all may be an illusion; and links to a New York story from 2018 titled "How Much of the Internet Is Fake? Turns Out, a Lot of It, Actually."

"I think it's entirely obvious what I'm subtly suggesting here given this setup," the post continues. "The U.S. government is engaging in an artificial intelligence powered gaslighting of the entire world population." So far, the original post has been viewed more than 73,000 times...

The theory has become fodder for dramatic YouTube explainers, including one that summarizes the original post in Spanish and has been viewed nearly 260,000 times. Speculation about the theory's validity has started appearing in the widely read Hacker News forum and among fans of the massively popular YouTube channel Linus Tech Tips. In a Reddit forum about the paranormal, the theory is discussed as a possible explanation for why threads about UFOs seem to be "hijacked" by bots so often. The theory's spread hasn't been entirely organic. IlluminatiPirate has posted a link to his manifesto in several Reddit forums that discuss conspiracy theories... Anyway ... dead-internet theory is pretty far out-there. But unlike the internet's many other conspiracy theorists, who are boring or really gullible or motivated by odd politics, the dead-internet people kind of have a point... [Y]ou could even say that the point of the theory is so obvious, it's cliché — people talk about longing for the days of weird web design and personal sites and listservs all the time. Even Facebook employees say they miss the "old" internet. The big platforms do encourage their users to make the same conversations and arcs of feeling and cycles of outrage happen over and over, so much so that people may find themselves acting like bots, responding on impulse in predictable ways to things that were created, in all likelihood, to elicit that very response.
That 2018 article in New York magazine had argued that (at that time) a majority of web traffic was probably coming from bots — including especially high bot traffic on YouTube — while even the engagement metrics for major sites like Facebook had been gamed or inflated.

But whether or not that's changed, the Atlantic shares a compelling argument from a forum poster arguing that their very presence in this discussion proves they must be a bot. "If I was real I'm pretty sure I'd be out there living each day to the fullest and experiencing everything I possibly could with every given moment of the relatively infinitesimal amount of time I'll exist for instead of posting on the internet about nonsense."

"Are You Ready for Sentient Disney Robots?" asks a headline at the New York Times. (Alternate URL here for a text-only version.)

"A new trend that is coming into our animatronics is a level of intelligence," a senior Imagineering executive tells the Times, showing off Disney's sophisticated new three-foot animatronic of the Guardians of the Galaxy character Groot. "This guy represents our future. It's part of how we stay relevant."

The animatronic Groot walked across the room to introduce himself to the Times' reporter. When I remained silent, his demeanor changed. His shoulders slumped, and he seemed to look at me with puppy dog eyes. "Don't be sad," I blurted out. He grinned and broke into a little dance before balancing on one foot with outstretched arms.
It's just part of a larger initiative to upgrade the park's tech in a variety of different ways: There are animatronics at Disney World that have been doing the same herky-jerky thing on loop since Richard Nixon was president. In the meantime, the world's children have become technophiles, raised on apps (three million in the Google store), the Roblox online gaming universe and augmented reality Snapchat filters... In early June, Disney's animatronic technology took a sonic leap forward. The Disneyland Resort's newest ride, WEB Slingers: A Spider-Man Adventure, features a "stuntronic" robot (outfitted in Spidey spandex) that performs elaborate aerial tricks, just like a stunt person. A catapult hurls the untethered machine 65 feet into the air, where it completes various feats (somersaults in one pass, an "epic flail" in another) while autonomously adjusting its trajectory to land in a hidden net... The Spider-Man robot — 95 pounds of microprocessors, 3-D printed plastic, gyroscopes, accelerometers, aluminum and other materials — took more than three years to develop. Disney declined to discuss the cost of the stuntronics endeavor, but the company easily invested millions of dollars...

One of Disney's senior roboticists, Scott LaValley, came from Boston Dynamics, where he contributed to an early version of Atlas, a running and jumping machine that inspires "how did they do that" amazement — followed by dystopian dread. Disney said it had no plans to replace human performers... Rather, Disney's newest robotics initiative is about extreme Marvel and "Star Wars" characters — huge ones like the Incredible Hulk, tiny ones like Baby Yoda and swinging ones like Spider-Man — that are challenging to bring to life in a realistic way, especially outdoors.... The development of Groot — code-named Project Kiwi — is the latest example. He is a prototype for a small-scale, free-roaming robotic actor that can take on the role of any similarly sized Disney character....

Cameras and sensors will give these robots the ability to make on-the-fly choices about what to do and say. Custom software allows animators and engineers to design behaviors (happy, sad, sneaky) and convey emotion.

68-year-old technology writer Charles Petzold wrote about Windows programming for 25 years, including several books published by Microsoft Press. In 1994 he was one of seven "Windows Pioneers" honored in a special ceremony (with an award presented by Bill Gates), and the company has also recognized him with their "Most Valuable Professional" award.

Petzold just wrote a blog post titled "Screw you, Microsoft Edge" when the browser spontaneously decided to advise him of a discount at Walmart. Recently while searching for a book on Bookshop.org, I was interrupted by a popup apparently generated by Microsoft Edge advising me of an alternative... Excuse me?

The assumption that I need help buying a book is the biggest insult I've encountered on Windows since the days of Clippy.

A further insult is the implication that I make buying decisions based solely on price... I might prefer a retailer that focuses solely on books, or a retailer that is not a large chain. More generally, I might make a decision based on the company's carbon footprint, or perhaps their reputation in paying fair wages, or what political candidates and movements they support, or whether the CEO uses his wealth to launch himself into space.

Of course, these concepts are entirely beyond the scope of Edge's braindead algorithm that apparently knows only whether one number is larger than another.
In November Microsoft had described the upcoming popups announcing better prices as "a proactive price comparison experience that meets you where you shop. When you're shopping, Microsoft Edge will check prices at competing retailers to let you know if a lower price is available elsewhere..."

Promising there'd be even more shopping experiences coming, they'd added, "we'd love to hear what you think of them so far!"

First Major League Baseball experimented with automated umpiring of balls and strikes in the minor leagues.

Now the Verge reports they're trying a time-saving tactic that might also make it harder to cheat: Baseball has a sign stealing problem — or at least, a technological one, seeing how reading another team's pitches is technically legal, but using Apple Watches or telephoto cameras and then suspiciously banging on trash cans is very much not. But soon the MLB may try fighting fire with fire: on August 3rd, it plans to begin testing an encrypted wireless communication device that replaces the traditional flash of fingers with button taps, according to ESPN.

The device, from a startup called PitchCom, will be tested in the Low-A West minor league first. As you'd expect from something that's relaying extremely basic signals, it's not a particularly complicated piece of kit: one wristband transmitter for the catcher with nine buttons to signal "desired pitch and location," which sends an encrypted audio signal to receivers that can squeeze into a pitcher's cap and a catcher's helmet.

The receivers use bone-conduction technology, so they don't necessarily need to be up against an ear, and might theoretically be harder to eavesdrop on. (Bone conduction stimulates bones in your head instead of emitting audible sound.)
"MLB hopes the devices will cut down on time spent by pitchers stepping off the rubber and changing signals," reports the Associated Press, noting another interesting new rule. "A team may continue to use the system if the opposing club's device malfunctions."

But don't worry about that, reports ESPN: Hacking the system, the company says, is virtually impossible. PitchCom uses an industrial grade encryption algorithm and transmits minimal data digitally, making it mathematically impossible for someone to decrypt intercepted transmissions, according to the company.

"How would you feel about being able to pay to control multiple aspects of another person's life?" asks the BBC.

"A new app is offering you the chance to do just that." When writer Brandon Wong recently couldn't decide what takeaway to order one evening, he asked his followers on social media app NewNew to choose for him. Those that wanted to get involved in the 24-year-old's dinner dilemma paid $5 (£3.50) to vote in a poll, and the majority verdict was that he should go for Korean food, so that was what he bought...

NewNew is the brainchild of Los Angeles-based entrepreneur Courtne Smith. The app, which is still in its "beta" or pre-full release stage, describes itself as "a human stock market where you buy shares in the lives of real people, in order to control their decisions and watch the outcome". For many of us that sounds a bit ominous, but the reality is actually far less alarming. It is aimed at what it calls "creators" — writers, painters, musicians, fashion designers, bloggers etc. It is designed as a way for them to connect far more closely with their fans or followers than on other social media services and, importantly, monetise that connection...

Whenever a vote is cast the creator gets the money minus NewNew's undisclosed commission... In addition to voting, followers can also pay extra — from $20 — to ask a NewNew creator to do something of their choosing, such as naming a character in a book after them. But the creator can reject all of these "bids", and if they do so then the follower doesn't have to part with the money...

Co-founder and chief executive Ms Smith, a 33-year-old Canadian, has big plans for NewNew, and has some heavyweight backers. Investors include Peter Thiel, the billionaire co-founder of PayPal, and the first outside person to put money into Facebook. Others with a stake in the business include leading US tech investment fund Andreessen Horowitz, and Hollywood actor Will Smith (no relation to Courtne). Snapchat has also given technical support.

xanthos (Slashdot reader #73,578) writes: Our friends over at The Register are reporting a zero day vulnerability for one of the earliest modern computer architectures.

Pontus Johnson, a professor at the KTH Royal Institute of Technology in Stockholm, Sweden, has published what amounts to a sql injection attack on the 1967 implementation of the simulated Universal Turing Machine (UTM) designed by the late Marvin Minsky. The exploit allow an arbitrary program to be run in place of the intended one. It has been dutifully documented as CVE-2021-32471. At this time there is no patch or workaround.

"Always the innovator, Elon Musk is crowdsourcing ideas for his upcoming Saturday Night Live appearance," writes USA Today.

SFGate reports: Both Musk fans and critics weighed in, with the tweet drawing over 4,500 quote tweets at time of publication (and 113,000-plus likes from his devotees). One of the top responses skewered his recent move to Texas.

"How about a skit where a selfish billionaire has a tantrum and makes a showy to-do about moving his factory to another state, but that new state is so dysfunctional it has a third-world power grid and runs out of electricity to run his factories and cars? That would be hilarious...."

As a result of his controversial image, "SNL" announced that cast members will not be required to act alongside him if it makes them uncomfortable. No cast member has publicly decline to perform yet, but cast member Chris Redd did jump into the Twitter fray to correct Musk on his use of the word "skit."
Page Six describes more of the suggestions from Twitter: Some commenters suggested ideas, including, "Extraterrestrials found your Tesla Roadster sent to space in 2018 & are trying to figure out what it is," "You play Chris Hansen on "To Catch a PP loan" with Ross Gerber," and, "Something about how it is all a simulation," while many of the responses to Musk's tweets were real zingers.

"You meeting with SNL writers using the same motivational techniques you use with $TSLA engineers. Elon: I need this done tomorrow or you're fired. SNL Writer: In your dreams a-hole," one user responded.

"There are simply too many points of uncertainty for us to move forward with confidence right now," explains a FAQ addressing this year's cancellation for the annual Burning Man festival.

"The physical, psychic, and emotional impacts of this pandemic are real and the recovery from this experience will happen at different rates of speed," organizers said in an announcement. "This is the time to gather with our friends, crews, families and communities..." They also argued that in an abstract sense, "Burning Man is happening right NOW, all around you," urging people to create experiences, opportunities and connection at the local level. (Their suggestions include planning to join a mass "Burn Night" livestreaming event on September 4, or preparing for "Virtual Burning Man" from August 21 to September 5, 2021.)

Last year's virtual event drew 165,000 participants, reports NPR, adding that this year's cancellation of a mass real-world gathering "has put many people in the event's host community at ease." Wary of a trend of rising coronavirus cases in some parts of the region, Washoe County's district health officer Kevin Dick said "the right call was made," in order to lower the risk of spreading infection.
And SFist also notes the festival's "Invitation to the Future" program "where $2,500 buys you a reservation to buy tickets whenever they do announce the event — but that $2,500 does not get you a ticket." "This is a reservation that will guarantee someone the ability to purchase a regular priced ticket for the next two editions of Black Rock City," the Burning Man Project communications team says in an email to SFist...

Per the fine print of this arrangement, there will be only 1,000 of these $2,500 reservations that are essentially tickets to buy tickets... "It's going very well!," Burning Man's communications team tells us. "We're so grateful for our generous community. As of this writing, we have only a few hundred left...."

Burning Man has to get creative, and maybe perks for big spenders is an acceptable one-time trade-off to ensure its ongoing solvency. The project has gone nearly two years since its last infusion of direct ticket revenue, and the permits and attorney fees necessary to pull off this event on federal land have not gotten any cheaper despite the pandemic.

Gizmodo reports: The latest big name to get in on the NFT craze is former intelligence contractor and whistleblower Edward Snowden, who on Friday auctioned off an original NFT art piece for roughly $5.4 million worth of the cryptocurrency Ether. Titled "Stay Free", it's a digital self-portrait made out of pages from a U.S. Court of Appeals decision that ruled the National Security Agency's widespread surveillance of phone records violated the law, a practice Snowden brought to light in 2013 by leaking classified NSA secrets to journalists...

The NFT sold for 2,224 Ether, worth just over $5.4 million at the time of publishing. All proceeds from this sale will go to the Freedom of the Press Foundation, a non-profit that develops open-source tools for whistleblowers and works to shield journalists from state-sponsored hackers and government surveillance. Snowden has led the organization as president since 2017.

"iCloud has had the occasional service issue, but its latest problem appears to be highly... specific," writes Engadget: Actor and author Rachel True claims iCloud has effectively locked her out of her account due to the way her last name was written. Reportedly, her Mac thought lower-case "true" was a Boolean (true or false) flag, leading the iCloud software on the computer to seize up. The problem has persisted for over six months, she said.

True said she'd spent hours talking to customer service, and that Apple hadn't stopped charging her for service. She could switch to the free tier, although she'd also lose most of her online storage if she did.
True has apparently resorted to imploring desperately in tweets to both @Apple and @AppleSupport. "Now that I a layman have explained problem to you a giant computer company, could u fix...?"

Science magazine describes what happens when a robot writes a play: The 60-minute production — AI: When a Robot Writes a Play — tells the journey of a character (this time a robot), who goes out into the world to learn about society, human emotions, and even death.

The script was created by a widely available artificial intelligence (AI) system called GPT-2. Created by Elon Musk's company OpenAI, this "robot" is a computer model designed to generate text by drawing from the enormous repository of information available on the internet. (You can test it here.) So far, the technology has been used to write fake news, short stories, and poems. The play is GPT-2's first theater production, the team behind it claims...

First, a human feeds the program with a prompt. In this case, the researchers — at Charles University in Prague — began with two sentences of dialogue, where one or two characters chat about human feelings and experiences... The software then takes things from there, generating up to 1000 words of additional text.

The result is far from William Shakespeare. After a few sentences, the program starts to write things that sometimes don't follow a logical storyline, or statements that contradict other passages of the text. For example, the AI sometimes forgot the main character was a robot, not a human. "Sometimes it would change a male to female in the middle of a dialogue," says Charles University computational linguist Rudolf Rosa, who started to work on the project 2 years ago... As it keeps going, there is more room for nonsense. To prevent that, the team didn't let GPT-2 write the entire play at once. Instead, the researchers broke the show down into eight scenes, each less than 5 minutes; each scene also only contained a dialogue between two characters at the same time. In addition, the scientists sometimes changed the text, for example altering the passages where the AI changed the character's gender from line to line or repeating their initial text prompt until the program spat out sensible prose.

Rosa estimates that 90% of the final script was left untouched, whereas 10% had human intervention.
It's a thought-provoking experience. (You can watch the whole play online -- with English subtitles.) The play's first lines?

"We both know that I'm dying."
"How do you know that you're dying?"
"I will die very soon."

And within seconds, the protagonist has asked the question: "How can you love someone who dies?"

In the year 2000, Metallica drummer Lars Ulrich answered questions from Slashdot's readers.

Late Friday night, the AV Club described Metallica's appearance at the opening ceremonies for the (now online) version of Blizzard Entertainment's annual event BlizzCon: The opening ceremonies were being broadcast online, both through the official BlizzCon page, YouTube, and Twitch. And you know what happens when licensed music gets played on the internet, don't you, folks? That's right: Copyright issues!

Per Uproxx, the audio of James, Lars, and the boys' performance apparently went out as per usual on YouTube and the BlizzCon page — although the whole thing appears to have been excised from the YouTube upload of the event. But on Twitch... On Twitch, things did not go so well. Which is to say that, even though it was being hosted on the company's official twitchgaming channel, the performance was ominously preceded by a chyron noting that "The upcoming musical performance is subject to copyright protection by the applicable copyright holder."

And then this happened....

Can we prove that someone at Twitch intentionally picked the dorkiest, most Zelda forest-ass music imaginable to have Metallica rock their little hearts out to, instead of broadcasting their extremely copyrighted music (and thus having to deal with the possibility of issuing one of their ubiquitous DMCA takedown notices to themselves)? Obviously not.... On the other hand, we can prove that it is extremely funny to watch this happen, especially — as many people have pointed out — since Metallica is at least partially responsible for the restrictive character of many online musical streaming laws that dominate the internet today, after their high-profile campaign against Napster way back at the dawn of the MP3.
In other news, Diablo II is being remastered and re-released later this year.

Slashdot reader DevNull127 writes: The U.S. Cyber Command, headed by the National Security Agency's director, has been a part of America's Department of Defense since 2009.

Each one has a hint — though that hint is just the number of words in the answer, as well as its number of characters.

A Slashdot reader shared an anonymous tip about "new consumer-grade artificial intelligence employed to restore 85 year-old Popeye cartoons, using only the available digital copies as sources for the remastering."

It's eerie to see vintage cartoons like Popeye the Sailor meets Sindbad the Sailor upgraded to high resolution. It's apparently the work of Cartoon Renewal Studios, a group "Dedicated to the loving and careful preservation of classic off-copyright animation" (according to its web site).

There's not much information, but Jim Ames of Cartoon Renewal Studios turned up in an online forum promising "we're restoring ALL the classic cartoons to brilliant 1080 HD so they can be enjoyed forever." I've been dreaming of this project for some time... We will be posting THOUSANDS of off-copyright cartoons digitally remastered and upscaled to 1080 HD. We can process about 50 cartoons a month, at this time... Hoping to scale up to 100 cartoons a month processing capability next month.

We could finish 1000 cartoons in 2021... stay tuned...

Slashdot reader DevNull127 writes: A new web quiz challenge visitors, "Can you tell a coder from a cannibal? A mathematician from a murderer? Try to spot who liked hacking away at corpses rather than computers."
One commenter on BoingBoing says the quiz brought back memories of doing IT recruitment in the 1990s. "After a few months at that job, I started to wonder if spending so much time staring at soulless equipment wasn't affecting people. Too many candidates were completely humorless, culturally clueless, or sporting a thousand-yard stare..."

"Behold the cakie: It has the crispiness of a cookie and the, well, 'cakiness' of a cake."

So says a triumphant blog post by Google Cloud's developer advocate and an applied AI Engineer for Google's Cloud AI. "We also made breakies, which were more like fluffy cookies, almost the consistency of a muffin" (or bread).

Food and Wine explains the project (in an article shared by Slashdot reader John Trumpian): Inspired by the pandemic-spawned spike in searches for baking, the team at Google Cloud "decided to dive a little deeper into the trend and try to understand the science behind what makes cookies crunchy, cake spongy and bread fluffy," according to a post on their blog. Then, once armed with that machine learning knowledge, they attempted to mix these attributes into what they bill as "two completely new baking recipes...."

[T]hese Google Cloud employees organized about 700 recipes covering cookies, cakes, and breads — standardizing measurements, isolating the key ingredients, and re-categorizing things like banana breads that aren't really "breads." Then, they fed them into a tool called "AutoML Tables" to create a machine learning model that was able to predict whether a recipe was a cookie, cake, or bread based on its ingredient amounts. ["If you've never tried AutoML Tables, it's a code-free way to build models from the type of data you'd find in a spreadsheet like numbers and categories — no data science background required," explains the blog post.]

Of course, recipes don't necessarily fit perfectly into one category. As Sara Robinson, who led the project, explained, a recipe might come back as 97 percent bread, 2 percent cake, and 1 percent cookie. So what if she asked the model to create its own recipe: something that's 50 percent cookie and 50 percent cake?

That's how the Cakie was born. And she was happily surprised by the results. "It is yummy," Robinson said. "And it strangely tastes like what I'd imagine would happen if I told a machine to make a cake cookie hybrid." Based on that success, she and colleague Dale Markowitz continued to tweak their model — which resulted in the Breakie.
"We should caveat that while our model gave us ingredients, it didn't spit out any baking directions, so we had to improvise those ourselves," the blog post explains. "And, we added chocolate chips and cinnamon for good measure." Robinson also built a prediction-making web app to help quickly experiment with different ingredient ratios.

They ultimately identified which ingredients were the biggest "signal" of cake-ness, cookie-ness, and bread-ness, concluding that "In our case, the amount of butter, sugar, yeast and egg in a recipe all seemed to be important indicators..."

The author of the book Online Afterlives describes the unusual projects of people like Eugenia Kuyda, co-founder of Luka, an AI-powered chat simulator that books restaurant reservations and makes recommendations. Kuyda worked with computer scientists to convert several thousand text messages between deceased tech entrepreneur Roman Mazurenko and his friends and relatives into a chatbot simulation: "How are you there?" asks a friend. "I'm OK. A little down. I hope you aren't doing anything interesting without me," Roman responds. His friend replies that they all miss him. Another acquaintance asks him if God and the soul exist. Having probably indicated his atheism in chats while he was alive, he says no. "Only sadness."

Not content with Luka, Eugenia also designed a chatbot called Replika. A cross between a diary and a personal assistant, Replika asks users a series of questions, eventually learning to mimic their personalities. The goal is to get closer to creating a digital avatar that would be able to reproduce us and replace us once we're dead, but also one that is able to create "friendships" with humans. Since the second half of 2017, over two million people have downloaded Replika onto their mobile devices...

Luka and Replika are not the only inventions designed to give a voice to the digital ghosts of the deceased. A few years ago, James Vlahos, an American journalist who has been an AI enthusiast since childhood, created what he calls a "Dadbot." It all started on April 24, 2016, when his father John was diagnosed with lung cancer. Upon learning of his father's illness, James began recording all of their conversations with the idea of writing a commemorative book after his father's death. After 12 sessions, each an hour and a half, he found himself with 91,970 words. The printed transcripts filled around 203 pages...

He decided to use the recordings of his father to create something other than a commemorative book. He remembered writing an article that discussed PullString (previously known as ToyTalk), a program designed to create conversations with fictional characters... James used PullString to reorganize the MP3 recordings of his father. He also used it to create his Dadbot, software that works on his smartphone and simulates a written conversation with John, based on the processing of almost 100,000 recorded words... The tone of the conversations reflects the personality of the deceased: "Where are you now?" asks James. "As a bot I suppose I exist somewhere on a computer server in San Francisco.

"And also, I suppose, in the minds of people who chat with me."
