Meta's AI Patent to Simulate Dead People Shows the Dangers of 'Spectral Labor'
Researchers say Meta’s patent for simulating dead users could be a “turning point” in “AI resurrections.”
Last week, Business Insider reported on a Meta patent describing a system that would simulate a user’s social media activity after their death.The patent imagines a world where you’d be able to chat with a deceased friend’s Facebook or Instagram account after their death, and have a large language model simulate their posting or chatting behavior.
Meta first filed the patent in 2023, but the patent made headlines this week because of its dystopian implications. And while Meta told Business Insider that “we have no plans to move forward with this example,” a recently published paper from researchers at the Hebrew University of Jerusalem and Leipzig University shows that generative AI is increasingly being used to puppeteer the likeness of dead people. The paper argues that the practice raises “urgent legal and ethical questions around posthumous appropriation, ownership, work, and control.”
“Meta’s patent is big, and might even be a turning point,” Tom Divon, the lead author on Artificially alive: An exploration of AI resurrections and spectral labor modes in a postmortal society, told me in an email. “What makes it different is the scale. In our research, most of the AI resurrections we examined were quite bespoke, projects started by families, advocacy groups, museums, or startups, usually tied to very specific emotional, political, or commercial contexts. Even when they existed as apps, they were optional and limited, not built into the core structure of a platform. Meta’s proposal feels different because it imagines posthumous simulation as something woven directly into social media infrastructure.”
Using technology to animate the dead or simulate communication with them is not new, but the practice is becoming more common because generative AI tools are more accessible. Divon and co-author Christian Pentzold analyzed more than 50 real-world cases from the United States, Europe, the Middle East, and East Asia where AI was used to recreate deceased people’s voices, likeness, and personality, to see how and why technology was used this way.
They say that the examples they studied fell into three categories:
The paper raises questions about this growing practice more than it proposes solutions. How does the notion of identity change when multiple versions of oneself can exist simultaneously, and what safeguards do we need to prevent exploitation of people after their death?
“The legal and ethical frameworks governing issues such as consent, privacy, and end-of-life decision-making demand reevaluation to accommodate the challenges posed by afterlife personhood,” the paper says. “In particular, to date, there is no clear line for governing the intricate intertwining of an individual’s data traces and GenAI applications.”
Divon told me that thinking about these issues is especially relevant when it comes to Meta’s patent. “Spectral labor describes how the dead can be made to ‘work’ again through the extraction and reanimation of their data, likeness, and affect. At small scale, this already raises ethical concerns. But at platform scale, we think it risks turning posthumous presence into an ongoing source of engagement, content, and value within digital economies [...] Meta’s patent makes us wonder, will individuals be given the ability to define their post-life boundaries while still alive? Will there be mechanisms akin to a digital DNR [do not resuscitate]?”
Divon explained that the current legal frameworks are not well equipped to address this technology because “digital remains” are typically approached either as property to be inherited or privacy interests to be protected. AI turns those materials into something interactive that can change and generate revenue in the present. Legislators, he said, should focus on getting explicit and informed “pre-death” consent requirements for posthumous AI simulation. Some laws that address this issue are already in progress.
“At its core, we believe the primary concern here centers on authorization,” he said. “Most individuals have not provided explicit, informed consent for their digital traces to power interactive posthumous agents. If such systems become embedded in platform infrastructure, inaction could quietly function as implicit agreement [...] We believe it is crucial to ask whether individuals should continue to generate social and economic value after death without having meaningfully agreed to that form of use.”

A Mystery Inside Earth’s Core Has Finally Been Solved With a Mind-Boggling Discovery
A new study indicates that vast oceans of hydrogen are locked deep inside our planet, helping to explain a strange “density deficit” and shedding light on the origin of life.
🌘Subscribe to 404 Media to get The Abstract, our newsletter about the most exciting and mind-boggling science news and studies of the week.
For decades, scientists have puzzled over the “density deficit” in Earth’s core, an unexplained discrepancy between the expected density of a solid iron core and the much lower density that is actually observed through seismic measurements of our planet’s center.
Now, scientists have provided some of the best experimental evidence yet that this deficit can be explained by vast oceans of hydrogen that are locked within the core, significantly lowering its overall density, according to a study published on Tuesday in Nature Communications.
In addition to constraining this longstanding problem, the research reveals new insights about another persistent mystery: the original source of Earth’s liquid water, the key ingredient that enabled life on our planet to emerge.
“Hydrogen has long been considered a major light-element candidate to account for the observed density deficit in Earth’s core,” said researchers led by Dongyang Huang, an assistant professor of Earth and space sciences at Peking University, in the new study. “For decades, however, our knowledge of the exact content of H in planetary cores has been hindered by the inability to unambiguously quantify H in high-pressure samples.”
To solve this problem, the researchers performed a series of experiments that simulated the extreme environment in the core during Earth’s formation billions of years ago. This approach involved heating up iron metal with lasers to a fully-molten state that resembles ancient Earth’s inner magma ocean, which reached temperatures up to 8,700°F, and pressures more than a million times more intense than those we experience on Earth’s surface.
The team then searched for the presence of hydrogen in nanostructures made primarily of silicon and oxygen. The results revealed that the core’s hydrogen percentage sits between 0.07 to 0.36 percent, which works out to roughly nine-to-45 times the amount of the hydrogen in all of Earth’s oceans.
But perhaps the most tantalizing part of the study is its implications for understanding the enigmatic origins of Earth’s water, the wellspring of life on our world.
Some theories suggest that Earth’s water was primarily delivered from extraterrestrial sources, such as comets and asteroids that impacted our planet as it was forming more than four billion years ago. An alternate possibility is that Earth’s water was largely sourced from its building blocks, including vast interior reservoirs of hydrogen. This latter scenario is supported by the new study.
“Although 71 percent of the Earth’s surface is covered by ocean, mainly made of H, it has been argued that the majority of Earth’s H had been stored in the core since its formation, ~4.5 billion years ago,” the researchers said.
The estimates presented in the study “require the Earth to obtain the majority of its water from the main stages of terrestrial accretion, instead of through comets during late addition,” the team concluded.
The study certainly helps tackle the mystery of the precise contents of Earth’s core, though the authors note that their estimate has large uncertainties that will need to be further narrowed down in future work. They also suggest that hydrogen alone cannot explain the density deficit, and that other light elements or compounds, including water, might be contributing to the discrepancy.
“Compared to existing models for Earth’s core composition this is a somewhat less H-rich core, and requires its density deficit to be accounted for by a mixture of light elements, rather than a single light species, akin to that of Mars’ core,” the team said in the study.
Given that water is essential to all life on Earth, solving the riddle of its origins is the first step to understanding how our planet came to be inhabited, and whether other planets may commonly go through the same process.
