‘Kid-pilled’ Sam Altman ‘constantly’ asked ChatGPT questions about his newborn | TechCrunch

Across hundreds of thousands of years of human existence, an impossible question has befuddled our species: why is the baby crying?!

Sam Altman, who is both the father of a three-month-old and CEO of OpenAI, hopped on OpenAI’s new podcast today to talk about how his company is impacting his experience with fatherhood. Altman, who describes himself as “extremely kid pilled,” said he was “constantly” using ChatGPT to ask questions about the behavior of babies during the first few weeks of his son’s life — now that he’s a bit more settled, he’s using ChatGPT to ask more general questions about children’s developmental stages.

“I mean, clearly, people have been able to take care of babies without ChatGPT for a long time,” Altman said. “I don’t know how I would’ve done that.”

This, obviously, isn’t fundamentally different from frantically Googling questions about babies, something that even the most well-prepared parents have been doing for decades. But, given who Altman is, his choice of internet tool to use is no surprise.

Still, when hallucination remains a challenge for AI products, it may be concerning to imagine relying so heavily on a chat AI for baby care answers.

But parents have been known to turn to many a questionable source for information in the middle of the night. My colleagues with children describe the “bottomless pit” of Google, and the minefield of parenting Facebook groups. Is ChatGPT really much different than taking the advice of someone online who’s insisting that you are a neglectful caretaker if you aren’t basing your baby’s bed time on the current phase of the moon?

Perhaps the idea of parents using AI in search for child-raising answers is less of a “primal alarm bell” then the idea of very young children using it, which Altman also discussed.

“There’s this video that always has stuck with me of a baby, or a little toddler, with one of those old glossy magazine [tapping] the screen,” Altman said. The child thought that the magazine was an iPad. “Kids born now will just think that the world always had extremely smart AI.”

Former OpenAI science communicator Andrew Mayne, who was interviewing Altman, recalled seeing a social media post from a parent who used the voice mode of ChatGPT to talk to his child about his obsessions.

“He got tired of talking to his kid about Thomas the Tank Engine, so he put ChatGPT into voice mode… An hour later, the kid’s still talking about Thomas the train,” Mayne said gleefully.

“Kids love voice mode,” Altman interjected.

As today’s parents turn to ChatGPT for all sorts of similar uses, this will likely end up reflecting the same repetitive discourse around the “iPad kid” generation (yes, it’s probably bad to let your kid watch hours and hours of “Cocomelon”; no, it’s not fair to expect parents to occupy their kid 24/7).

But existing children’s media is at least, for now, created by a team of humans, while ChatGPT’s own policies recommend it not be used by children under age 13. It does not have a vetted parental controls mode. Even Altman is aware of the risks, he said.

“It’s not all going to be good. There will be problems,” Altman said. “People will develop these somewhat problematic, or maybe very problematic parasocial relationships, and society will have to figure out new guardrails.”

Altman is correct. We do not fully know the effect of letting kids talk to a large language model about Thomas the Tank Engine for an hour. But at the end of the day, Altman is the head of a massive company spending billions and billions of dollars with the hope of building AI that is smarter than humans, and he never forgets that in his messaging.

“The upsides will be tremendous!” Altman said. “Society in general is good at figuring how to mitigate the downsides.”

For decades, scientists assumed that this literally continent-sized block of ice rested on an expansive and stable chunk of Earth’s crust known as a craton. A team of researchers has now complicated that picture—mapping a vast, interconnected geological structure that fans out from a troubling “tectonic deformation.” Beneath this ice sheet, thinner and more geologically recent slices of crusty lithosphere fan out into hidden valleys called “pull-apart basins.”

These basins—30 elongated wedge-shaped valleys in total—constitute an entirely new, continental-scale geological region underneath Antarctica, in fact, one which the researchers have named the East Antarctic Fan-Shaped Basin Province (EAFBP). But it’s how they likely formed that has now caught researchers’ attention.

To put it bluntly, it turns out that about 90% of the planet’s fresh water ice may not be on solid ground. Geologist John Goodge called the team’s findings “provocative” in an independent commentary on the new study, published Thursday in the journal Nature Geoscience.

“East Antarctica is typically considered from seismic tomography and geodetics to be ancient and generally stable,” according to Goodge, who studies continental tectonics with the nonprofit Planetary Science Institute. “[But] something else is going on at depth.”

Continental divides

Goodge speculates that this seemingly “coherent pull-apart system,” as presented in the new study, might help explain a variety of mysterious heat and water flows beneath this ice sheet’s surface, like that enormous subglacial lake identified in 2016 or some of the hundreds more like it.

The study’s authors, led by geophysicist Egidio Armadillo at the University of Genoa in Italy, agreed: “Because these basins underlie about half of the East Antarctic Ice Sheet, they are likely to heavily influence both ice-flow and landscape evolution,” the researchers wrote in their study, also published Thursday in Nature Geoscience.

Armadillo’s team, coordinating across Europe and the U.K., developed their new understanding of Antarctica’s hidden bedrock via an exhaustive set of sensory data. Gravitational and magnetic anomalies were mapped via low-altitude airborne surveys. Ground surface features were mapped with seismic tools, using sound waves that vibrate through the ice and ping back information about subglacial landscapes in 3D.

Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica
                The East Antarctic Ice Sheet is almost unfathomably huge. Covering about 75% of the entire frigid continent (nearly everything on its side of the Transantarctic Mountains), the sheet covers about 3.9 million square miles (10.2 million square kilometers) and extends down 1.4 miles (2.2 km), on average, before coming into contact with Earth’s surface. At its deepest, the ice plunges down over 3 miles (4.9 km).

Credit: Nature Geoscience All of this data—the fruits of “multi-national efforts to image within and below the ice sheet,” as Goodge put it—had already revealed that regions of the continent were “undergoing more rapid movement and ice-mass loss than previously recognized.” Armadillo’s team merely helped to explain why.

 The mechanism Armadillo and his colleagues proposed for the formation of these fan-shaped basins is called “distributed rotational extension.” It involves points called Euler poles around which tectonic plates pivot or rotate rather than smash into each other or pull apart. The result is a bit like decks of cards being spread out on a table, thinning out the stack of Earth’s crust as it moves. An icy situation Goodge took pains to spell out the basins’ implications for melting Antarctic ice due to climate change and the risk of rising global sea levels.

 The mere existence of these basins, he wrote, “could introduce widespread, systemic instability to the East Antarctic Ice Sheet” via thinner layers of Earth’s crust and more heat flow from below. On top of that, a series of fault-line “troughs” documented between the basins appear “tailor-made to promote outward flow of ice streams from the interior” into the world’s oceans, he said. That said, the team’s findings are unlikely to end this debate. As Goodge noted, Antarctica is “the last continental frontier of scientific exploration.” It’s still a very mysterious place, one that’s challenging to study given its inhospitable temperatures and extreme geography. Its “cryptic subglacial geology” might stay that way for a while.      #Scientists #ContinentSized #Geological #Structure #Hiding #Beneath #AntarcticaAntarctica,Geology,mapping,Plate tectonics

Ahead of this year’s World Cup, Amnesty International warned that millions of fans attending the tournament are at risk of attacks on their human rights, especially in the United States. The organization added that the tournament, which will also be held in Mexico and Canada, could take place amid severe restrictions on freedom of expression and peaceful assembly.

In a report titled “Humanity Must Win: Defending Rights, Tackling Repression at the 2026 FIFA World Cup,” Amnesty outlines a range of risks faced by fans, players, locals, and media attending the tournament in its three host countries.

In the US, where three-quarters of the World Cup matches will be played, the report finds there is a “human rights emergency” characterized by racial profiling and mass detentions by agencies such as Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP).

“This World Cup is far from the ‘medium risk’ tournament that FIFA once judged it to be,” the organization wrote. “The joy that fans hope to experience over a six-week celebration of football is overshadowed by the reality of violent arrests, mass detention,” and other abuses.

Earlier this year, then-acting ICE director Todd Lyons said ICE would be a “key part” of security during the World Cup. Since then, the extent of ICE’s role has not been fully clarified. But in May, Department of Homeland Security officials told NBC News that ICE is offering its personnel to local police departments to help with security during World Cup matches.

Amnesty International’s report indicates that in Mexico federal authorities have announced the deployment of around 100,000 security agents, including members of the army, in response to high levels of violence. According to Amnesty, this decision increases the risk for those demonstrating, including a movement of searching mothers who have planned peaceful protests in the vicinity of the Banorte Stadium (formerly Azteca Stadium) in Mexico City to demand transparency, justice, and reparations for the 133,500 disappearances registered in the country. This initiative is expected to be joined by other mobilizations during the tournament, linked to access to land, water, housing, and criticism of gentrification.

In Canada, the report notes, there are fears that the country’s housing woes will lead to unhoused populations in host cities like Toronto being displaced by World Cup activities.

When Amnesty released its report in March, the organization claimed only four of the 16 host cities had published plans for the protection of human rights during the tournament. It recommended that host cities avoid the use of military forces in civilian security tasks and stressed that local authorities should ensure that World Cup events and venues were not subject to immigration raids.
