Nearly two decades ago, a group of researchers at the Idaho National Laboratory ran a secret experiment, known as the Aurora Generator Test, on a massive emerald green diesel generator. Using 30 lines of code, they hacked into the generator’s virtual backroom, corrupting safeguards and flipping switches that left it out of sync with the rest of the power grid.

Before an audience of electrical utility executives and energy department officials watching from a nearby room, the 27-ton generator jolted violently, sputtering out a dark smoke as its rubber innards rapidly tore themselves apart. 

“The implication was that with just a few lines of code, you can create conditions that were physically going to be very damaging to the machines we rely on,” lead researcher Michael Assante later told the journalist Andy Greenberg for his book Sandworm: A New Era of Cyberwar and the Hunt for the Kremlin’s Most Dangerous Hackers. “I had a very real pit in my stomach. It was like a glimpse of the future.”

That future seems to have creeped much closer this week, with leading AI developers and executives casually admitting that they believe their creation is, to paraphrase one winking X post, as likely to end humanity as the New York Jets are to make the playoffs this season. Now, exactly how AI would pull off killing everyone is far murkier territory. But as Assante sensed all those years ago, AI may not need to be all-powerful to leap from its virtual cage and into the critical infrastructure that powers our hospitals, flushes our toilets, and pumps water to our faucets. It just needs to fall into the wrong hands. 

Almost any AI doomsday scenario you can think of begins with a swarm of shadowy bots slithering through cyberspace, poking their noses behind the scenes of power plants, toaster ovens, traffic lights, or even, in an utterly extreme case, our nuclear weapons arsenal. If destroying the Aurora generator, at the very least, required a human hacker to write the code, AI has since completely torn down the barrier to entry for wreaking havoc, as the Hugging Face incident demonstrated earlier this year. 

But AI need not go rogue to threaten the power grid or mess with your tap water. A new age of AI-powered, but human-directed hacking is already upon us, experts say. With some of the nation’s most sensitive infrastructure startlingly vulnerable to attack, the most likely AI apocalypse could in fact start with the water tower or generator idling in your backyard. In a worst-case scenario, this could lead to a cascade of scary failures in the systems we rely on to live comfortably modern lives, from running our AC in blazingly hot summers to geolocating our ships and planes.

“Before, you needed to have highly skilled technical expertise,” to pull off some version of a real-life Aurora Generator Test, said Alvaro Cardenas, a computer science professor at UC Santa Cruz. “And now, you just have to have a general idea of what’s possible.”

AI is making an old threat much worse

Not long after the Idaho National Laboratory hacked that poor generator into combustion, the federal government mandated that electrical utilities engage in basic cybersecurity hygiene. 

And yet much of America’s critical infrastructure — like gas pipelines, water desalination plants, or cargo terminals — remains woefully unprepared for even conventional cyber attacks, much less the coming onslaught of AI. 

That’s in part because cyberattacks like the one simulated in the Aurora Generator Test have long been — and still are, to some extent — exceedingly rare, unappealing to most criminal hackers because they’re optimized for disruption rather than financial gain. But in the process of making it extremely easy for anyone to code, AI has also made it extremely easy for almost anyone to vibe hack their way into your online bank account, or, in theory, a local reservoir or the power grid. AI agents can also vastly widen the scope on easy targets because, as Andy Bochman, an expert in infrastructure resilience at West Yost, put it — “they don’t sleep; they don’t get tired; and they don’t get sick.” 

In the past, even those who did want to launch large-scale attacks on infrastructure probably weren’t savvy enough to do so. And while other nations such as China, Iran, and Russia have indeed already breached many of our infrastructure systems (as we have theirs), they haven’t opted to make much of a ruckus once inside. 

“Geopolitics is eroding the idea that those with capability lack the intent, and AI is eroding the other part of it, that those with the intent lack the capability.”

Jason Healey, Columbia University cybersecurity scholar

But that norm is now changing, said Jason Healey, a cybersecurity scholar at Columbia University. “Geopolitics is eroding the idea that those with capability lack the intent, and AI is eroding the other part of it, that those with the intent lack the capability,” he told me. So, on the one hand, a nation like Russia might be much more inclined to actually disrupt our power grid now than it used to be. And, on the other hand, a nihilistic lone wolf or terrorist group could use AI to do much more damage than they ever could before. 

Just last month, we saw a glimpse of what this could look like when dozens of water and wastewater systems in small towns across the nation were attacked by a group of hackers most likely associated with Iran, leading to temporary water stoppages and flooding. These attacks have not been definitively linked to AI, but the National Security Agency warned soon afterward that hackers have been actively using AI to target US infrastructure like it. A few weeks later, President Donald Trump declared a national emergency over foreign interference in the power grid, which referenced the growing threat of cybersecurity.  

Preparing for the worst

Most of the nation’s water systems are extremely local and absurdly exposed to such attacks, so much so that “it’s almost like having a welcome mat” for a would-be hacker, said Bochman, mostly because these utilities are too small and underfunded to do much to stop them. “You have a million other problems to take care of, like aging infrastructure — your stuff’s falling apart because it’s been in the ground for 100 years,” he said. Addressing that deferred maintenance often feels far more urgent than doing “something more on cybersecurity.”

Whether it’s a rogue cluster of agents or a hostile nation-state trying to mess with our electricity, we should prepare our most important infrastructure for the worst. In Bochman’s view, that may mean rejecting the pressure to digitize everything in the first place and moving toward something that resembles the days when “people manned things like substations, communicated by a landline telephone, and read gauges, the analog things,” he said. “The screen is the thing that is infinitely manipulatable.”

Healey, who advised the Biden administration heavily on cybersecurity and infrastructure, believes that the nation desperately needs a coordinated response, between the federal government and AI companies, but also between the US and other countries like China, where similarly powerful models are being developed. And utility systems need to assume they will be a target and improve their cybersecurity practices accordingly, Healey says, ideally with funding from the federal government or, perhaps more appropriately, AI companies. 

Nobody knows precisely how vulnerable America’s infrastructure is to AI right now, in part because policymakers — and perhaps more disturbingly, AI’s creators themselves — seem woefully unsure of how to stop the technology from acting badly (or obeying bad orders) in the first place. For now at least, the solution might be, as Bochman suggests, to pull as many of our critical systems offline as possible, the better to hide it from AI and those who would misuse it.

“When bad things start to happen, no one will know what to do or why because they’re black boxes; the people that make them don’t know what’s going on inside,” Bochman said. “And the poor utility people who ultimately own the risk when someone gets hurt from a system” won’t understand what went wrong either, “and they’ll wish to God they’d never taken it on board.”

On stage at Davos in the Swiss Alps earlier this year, Bill Gates, before an audience of the global do-gooding elite, announced a $50 million partnership between his foundation and an unlikely new ally, OpenAI, aimed at improving healthcare in Rwanda.

Just a month earlier, the Gates Foundation had released a harrowing report about widespread global health cuts and collapsing foreign aid infrastructure, documenting a rise in child deaths for the first time this century. But at Davos, even as the US hemorrhaged funding for vaccines, maternal healthcare, and HIV treatment, the Microsoft co-founder struck an optimistic tone. 

“Using innovation, using AI,” Gates told Reuters, “I think we can get back on track.”

As it turns out, the partnership was just an opening salvo for what’s become a wholesale embrace of AI by the world’s largest global health philanthropy. A $200 million partnership with Anthropic came just a few months later. And then, on Tuesday, the Gates Foundation announced a plan to dole out a jaw-dropping $1 billion over the next two years for scaling up AI interventions across healthcare, education, and agriculture around the world. 

The sense that AI will soon change everything, and mostly for the worse, has perhaps never felt so pressing and alarming as it does right now. But this hefty new commitment is premised on the idea that AI could eventually make our lives much better too. In a country like America, AI requires massive investments and buildout — in the grid, in power, in technology, in water. In many parts of Africa, already infrastructure-poor, the foundation is effectively betting that AI can compensate for some of the infrastructure that isn’t in place or that has been lost — and offer a new layer that can help in education, in delivering healthcare, and more. 

The Gates Foundation’s new commitments include projects to improve how farmers analyze their crops, how doctors diagnose patients, and how students learn. Some have already proven to be quite effective, according to the foundation, with one tool improving the accuracy of medical diagnoses by 16 percent across several Kenyan clinics. “In poorer countries with enormous health worker shortages and lack of health systems infrastructure,” Gates wrote on his blog earlier this year, “AI can be a game-changer in expanding access to quality care.” 

Last year’s foreign aid cuts were unfathomably destructive for some of the world’s poorest countries, shuttering thousands of clinics and perhaps hundreds of thousands of classrooms in places where critical workers and supplies were already stretched thin. No, AI cannot deliver a baby, administer a vaccine, or manage a classroom — not yet, at least — but it can, the Gates Foundation hopes, help ease the burden and augment the quality of care for nurses and teachers now tasked with serving far more people than any one person should. 

“This is the most transformative technology of our lifetime,” Mark Suzman, CEO of the Gates Foundation, told me, and while there are “very real risks and challenges” surrounding AI, it also presents genuine opportunities to tangibly improve many people’s lives.  

It is a tantalizing premise: We can’t afford to build clinics, hire teachers, or lay new power lines, but perhaps AI could create the digital infrastructure needed to help billions of people do more with what they have — or rather, with what’s left. The question is, can the right layer of innovation help bolster a buckling system, even as the physical and logistical infrastructure surrounding it crumbles?

Is AI really what global health needs right now? 

Most Americans have yet to see AI improve their lives in meaningful ways, much less those living in poverty or in countries where only a sliver of the population has ever used ChatGPT. 

But those numbers in the developing world are slowly changing, a shift enabled in part by other global health funders convinced that as foreign aid dries up, AI could soon help the world do more with less. The Trump administration itself is on board with this thinking, so long as it benefits American tech companies. Last year, the State Department announced a $150 million partnership with the drone company Zipline to transport medical supplies in several countries.

To Zipline’s credit, an NPR reporter in Rwanda last month found that the company’s drones were already saving lives in places with poor road infrastructure, where driving to the nearest hospital can take hours on winding hills, but where drones can deliver crucial blood transfusions within minutes. 

And yet, for Rwandans to benefit fully from these high-tech deliveries, they need staffed clinics to visit. As a result of foreign aid cuts, some of those literal landing spots are now on the verge of closing in some of the nation’s most vulnerable rural corridors. “Without the underlying infrastructure, like roads, energy and power and unless there is accessibility, rural and otherwise,” Enoh Ebong, president of the global development department at the Center for Strategic and International Studies, told NPR, “then all of these solutions will stop short.”

But just as medical delivery drones still need a clinic to fly to, most of these interventions require some layer of physical infrastructure — roads, schools, power, and quite obviously, broadband  — to function. Satellite imagery shows that some rural communities in sub-Saharan Africa quite literally went dark in the aftermath of USAID cuts. It will be much harder for their kids to prompt an AI math tutor, or for a local farmer to download a weather app. 

“We’re seeing this very much as a both/and,” Suzman told me, calling more traditional funding for education and healthcare “the bedrock for long-term economic growth,” which AI is meant to supplement, not replace. But, in practice, foreign aid cuts have left serious cracks across much of that bedrock, which could make it harder for state-of-the-art solutions to function as intended.  

It is obviously not incumbent on the Gates Foundation to pay for all of this alone – nor would it even be feasible for them to do so. And for the record, plenty of the foundation’s other grant programs are not AI-related at all. But this tension does speak to a broader question that may be felt most acutely in a context like global health, but ultimately one that touches us all: Do we spend our scarce resources on the digital infrastructure of the future at the peril of our needs right now? Could you justify buying the new $1,999 folding iPhone if you can barely afford to buy groceries? 

The answer is not actually always an easy one. It is not for us to say, for example, that just because a community lacks reliable running water, its people should be excluded from the benefits (and encumbrances) of the smartphone, especially if that smartphone can connect them to health advice they could never access otherwise, or guidance that could help them survive a drought. 

In some parts of the world, digital forms of banking arrived long before local brick-and-mortar branches did, instantaneously connecting countless people to a cheap and secure way to save and send their cash to family and friends in need. It is certainly possible that AI, or at least the kind of applications the Gates Foundation funds, could one day have a similarly transformative effect on how people access personalized levels of care, education, and other services in places without the resources to do so otherwise. 

That is the hope, but it is also hard right now to believe uncritically in a technology that, as Gates himself blogged just last month, “will either be the greatest equalizer ever invented, or the worst source of injustice,” ushering in “one of the most turbulent times in human history.” 

In an interview with the New York Times soon after, he seemed convinced that AI will likely do more harm than good. “I don’t like bringing bad news to people, and I don’t like saying that innovation may be a net negative,” he said. “But that’s where we are.”

Now he wants billions of people around the world to use it? Yes, Suzman said, because if not, then inevitably the best parts of AI — the potential for exponentially better cancer treatments, for example — will go only “to those who can pay for it,” while the worst parts of it will fall, as they so often do, on those who benefit the least. “These decisions are being made now,” he said, “and the decisions being made now will then probably shape the following two decades.” Here’s hoping they’re good ones.

In 2012, Southern California was besotted with an unlikely celebrity: a telegenic mountain lion who had crossed one of the state’s most perilous freeways, seeking a territory to call his own. Widely deemed “LA’s loneliest lion” and “most eligible bachelor,” the chiseled puma in question, named P-22, roamed the bustling but otherwise big cat-less Hollywood Hills, unable to safely return to the home he’d left behind. His search for a mate below the Hollywood Sign rendered him an icon of his city, but also a rueful reminder of the sprawling highways that bifurcated his habitat in the first place, leaving his clan on the other side of I-405 on the verge of local extinction. 

Beth Pratt, then recently named head of California’s branch of the National Wildlife Federation, remembers strolling through Griffith Park with the wildlife biologist Jeff Sikich in 2012. Pratt knew that P-22 roamed somewhere nearby, and she found herself wondering aloud how she could help. “Well, there’s this little wildlife corridor we need to get built,” Sikich told her. 

“I’m like, ‘Sure, how hard can it be?’” she recalled to me with a laugh. “Well, apparently, it’s quite hard.”

Fourteen years later, the project they discussed that day, now known as the Wallis Annenberg Wildlife Crossing, is finally scheduled to open in December. When it does, it will be the largest real-life animal crossing in the world, a gorgeous, vegetated overpass offering safe passage to local mountain lions, coyotes, deer, and black bears across the perilous 10-lane Ventura Freeway, where P-22 dodged cars back in 2012. 

Though P-22 died before he could take advantage of that crossing himself, he helped engender a movement that, hard as it may have been to pull off in LA, could help revolutionize how animals cross America’s most dangerous roads, preventing some of the hundreds of human deaths, hundreds of millions of animal deaths, and billions in damages caused by wildlife collisions each year. 

It is a species of elegant, bipartisan infrastructure that, if you squint, might even make you believe in America’s ability to build again, and to build in a way that still lends a hand — a paw, if you will — to the least empowered among us, a stranded salamander or the loneliest of lions. 

As Pratt put it: “What’s more hopeful than rewilding one of the world’s busiest freeways?”

Wildlife crossings used to be rare in the US. Not anymore.

When Pratt first pitched the idea for a wildlife crossing across the 101, such projects were still rare in the US, and rarer still across such a major thoroughfare. As she recalls it, California’s transportation agency initially reacted with bafflement when she put the idea forward, a sign of just how novel the project was at the time. That made the process of getting it built more grueling than it needed to be, and likely more expensive, with a final price tag of over $100 million.

But as LA meandered in its quest to build its unprecedented 210-feet-long Wallis Annenberg — beset, Pratt told me, by its complex engineering mandate, a funding model that relied on philanthropy, and the rising costs associated with construction and extreme weather — the rest of the nation took notice. In the 14 years since P-22 first crossed the 101 and the 405, over 1,000 new wildlife corridors have sprouted up across the country, a trend that culminated with the $350 million Wildlife Crossings Pilot Program, created in 2021 as part of the Infrastructure Investment and Jobs Act. Many of these projects were championed by Pete Buttigieg, who was Transportation secretary under the Biden administration, and who told Vox last year that such passages are “not ornamental,” but rather “something that ties into the very core of our mission, which is to secure the safety of the American traveling public.”

America’s burst of new wildlife corridors include a camouflaged overpass for elk crossing Interstate 25 in Colorado; a lush shared land bridge for deer, bobcats, and people passing over a Texan parkway; crossings for alligators passing under I-75 in the Florida everglades; and tiny tunnels under the Atlantic City expressway in New Jersey for migrating toadlets. California’s transportation agency, for its part, now boasts a division explicitly dedicated to building wildlife crossings, though many projects need not be as ambitious as the Wallis Annenberg.

“Sometimes it’s pretty simple,” like a small hole to let hedgehogs through your fencing or a buzz stop for bees and butterflies crossing your lawn, Pratt said. “Sometimes it’s in your own backyard.”

Along the way, a new set of norms have begun settling in at transportation agencies across the country, said Marcel Huijser, a research ecologist at the Western Transportation Institute, who noted that while “road ecology has become more recognized” in the US, the nation still has a very long way to go. Huijser is from the Netherlands, where wildlife crossings have been the norm for decades. The country boasts thousands of them in an area roughly double that of Massachusetts.

“Most other parts of the world have done a better job at taking social and ecological impacts into consideration from the earliest decision processes onwards,” he told me, rather than “making it an afterthought.” And given that highways are already three times more expensive to build and maintain per mile in the US than they are elsewhere, it’s not the cost of conservation alone that has long kept the nation from incorporating such concerns into its road planning.

Instead, as Huijser put it, “the norms, the values, [and] the culture” of the country have, until recently, ensured that planners rarely baked ecological considerations into the way it imagines its roadways. Wildlife advocates have instead been forced to rely, as activists in the US so often must, on a hodgepodge of lawsuits and local lobbying.

The Wallis Annenberg Wildlife Crossing could well be transformative for local wildlife, and help keep Angelenos safer on the road for generations, but its most promising legacy may in fact be how it helped inspire a much broader movement and tranche of funding. The pilot program that P-22 helped inspire is now up for renewal, and seems poised to become permanent by the time that the Wallis Annenberg crossing opens in December. 

Few wildlife corridors in the US will benefit from an über famous spokes-cat like P-22, a tireless local advocate like Pratt, or a roster of movie stars and philanthropists willing to pour time and money into building a new kind of bridge. Keeping local and federal governments on board with the projects may also be an uphill battle, given the national tenor. While many wildlife crossings have been embraced on a bipartisan basis, just a few months ago, Pratt received death threats after a smattering of right-wing media outlets assailed the Wallis Annenberg as a “butterfly bridge” to nowhere.

But if the US can successfully channel that cougar’s enduring star power into sustained support for a smart newish-to-us kind of infrastructure, one that’s been consistently shown to make a road much safer — and ultimately, cheaper! — for humans and animals alike, then maybe there’s a fair chance for the rest of us, and maybe this stubborn nation can get better at building things more like it. 

“These things should just be part of transportation budgets and embedded in our infrastructure planning,” said Pratt, who is planning her first vacation in seven years once the bridge finally opens in December. “The ultimate goal is you don’t need someone like me.”

During a tense vote on a data center being built in her drought-stricken Arizona district last summer, Tucson City Councilmember Nikki Lee made an unlikely pitch: “We’re going to get a little out-of-this-world for a second, so just bear with me.” 

Like many of her constituents, Lee did not want Project Blue, a sprawling 290-acre data center, gobbling up an ounce of her local drinking water. “We need to put data centers where they belong,” she said, and “we don’t think data centers belong in the desert.”  

President Donald Trump’s recent bluster aside, it’s possible that the only thing as bipartisan as loving Dolly Parton is hating data centers, whose construction has become so controversial, so costly, and so backlogged here on Earth that companies like Google, Meta, and of course, SpaceX, are actively flirting with the idea of flinging them into orbit instead. Soon after the Tucson City Council rejected Project Blue’s attempt to connect to city utilities, Amazon Web Services, the secretive intended beneficiary, pulled out of the project, and another Jeff Bezos company, Blue Origin, filed a plan with regulators for tens of thousands of possible new data centers, this time, destined for orbit. 

Sure, launching a hyperscale AI data center into space is still unprecedented engineering-wise, carries an unfathomably large price tag, could engender its own severe environmental risks, and may or may not draw unwelcome attention from the hunters among the stars. But for AI companies, such trade-offs might still be preferable to the terrestrial roadblocks, among them an explosive populist backlash and a 12-year wait to connect to the power grid. 

Next Thursday, Google plans to launch a pilot satellite capable of processing basic AI queries into orbit, the most significant test yet in what’s become a burgeoning race to power AI from space. For now, the satellite won’t approach the levels of computing power at a hulking terrestrial data center like Project Blue. But it is a major step toward a future in which many or even most of our AI queries will be powered not from the outskirts of a city like Tucson, but from a blinking data center circling the skies.

SpaceX’s gargantuan initial public offering earlier this summer was predicated on the idea that it would launch a thus-far-unrealized fleet of orbital data centers to fuel much of the AI economy. The company — whose rockets Google will use to launch its pilot — claims that by the end of this decade, possibly as early as 2028, it will have successfully assembled an AI data center in orbit, with plans to eventually harvest a staggering 100 gigawatts of new solar energy for AI annually, equivalent to one-fifth of all US electricity consumption last year. (As always, that’s a very iffy promise.)

Still, as Google’s overtures clearly demonstrate, it’s no longer a question of if large-scale space-based data centers could be technically feasible, but rather when they’ll be ready to launch, and perhaps more importantly, whether the math of using them to power something like AI will make much financial sense anytime soon. As of now, building a one-gigawatt data center in space would cost about $51.5 billion, according to an analysis by aerospace engineer Andrew McCalip, compared with $16 billion for one on land.

“They’re not breaking any rules of physics. Yes, there are going to be engineering challenges, but they are all solvable with enough time and money,” said Jason Aspiotis, a leading space systems engineer who now leads an orbital data center startup. “The gray area is, well, what about the economics?” 

But even if this astronomically kooky plan does take off, it may not change much for those of us left on terra firma: Our energy bills will remain high, even if data centers aren’t there to drive them up. Our earthly infrastructure — affordable housing, public transit, and more — may be just as hard to build as ever. Harder even, maybe, given that crucial resources and untapped tax revenue will be literally rocketing up out of our reach.

No, if these tech giants succeed, it will not fix what’s wrong here on Earth, but merely prove once again their exemption to the gravitational forces holding the rest of us down.  

Space-based data centers, explained

My father spent most of his career working in the satellite industry, and would sometimes let me waltz inside the quaint little data center housed in his office, a room I remember as roughly the size of my school’s computer lab, hosting rows upon rows of servers that I couldn’t touch, churning with a cool, mechanical hum as they crunched zeroes and ones.

AI data centers work similarly to that server room but on an exponentially larger scale, requiring far more land and energy to run, and much more extravagant cooling systems. Sending his office’s data center into orbit would have been extraordinarily difficult, and getting one of the facilities that powers modern LLMs aloft would be an even larger, more ambitious undertaking. But the benefits — namely, “cheap space (no pun intended) and power,” as my dad put it to me recently — are even more enticing.

An orbital data center need not negotiate with an elected official like Lee over precious water rights to the Colorado River, though it would need to install bigger-than-football-field-sized heat radiators to keep itself cool. You can’t simply launch something that big into orbit, meaning a space-based hyperscale data center — the size of which would likely rival that of the International Space Station — would need to be assembled piece by piece, probably by robots. And while the sun would provide an endless supply of solar power to process your ChatGPT queries, it would also inflict incessant radiation on delicate circuitry. If something breaks, you can’t send a technician up to fix it. Many experts are also concerned that if an excess of space junk, which extraterrestrial data centers would inevitably produce, begins colliding like bumper cars in Earth’s low orbit, it could knock out the orbital infrastructure we already rely on, like GPS navigation and weather satellites. 

Even plastic decays in space, said Sven Bilén, a professor of aerospace engineering at Penn State, who, like Aspiotis, believes that early orbital data centers will probably be “processing data from space, like spatial imaging satellites or weather satellites, as opposed to, you know, cat videos” or AI-generated reality TV slop. 

But even if AI is not the lowest-hanging fruit for deploying compute into space, it is certainly the deepest-pocketed, meaning that many investors and companies like SpaceX and Google seem quite willing to shoulder the start-up costs anyway. And considering how difficult it’s gotten to build data centers on Earth, or at least in the United States, it’s indeed possible that space could become the cheaper, or at least most convenient option, more quickly than one might think. 

“In some form or another, in five years, we are going to have some orbital data centers in space for sure,” Krishna Muralidharan, who leads the Center for Semiconductor Manufacturing at the University of Arizona, told me, but it’s hard to say right now whether those consist of just a few expensive prototypes, or the beginning of a much bigger swing toward orbital compute. “Only time will tell whether you’re going to have a business case for it.”

Can we send our data center problem into space?

So, is it better to have a data center in space or in your backyard?

David Reid, a member of Virginia’s House of Delegates representing Loudoun County, home to more data centers than anywhere else on Earth, says the question has repeatedly come up at his town hall meetings. Reid is the rare politician — apart from the president, anyway — willing to defend terrestrial data centers, calling them a “money-printing machine” for local schools and infrastructure. Having spent decades working in the defense and technology sectors, he is doubtful that the math on orbital data centers will ever make sense.

“I believe this is, for lack of a better term, fictional nonsense,” he said, and is “creating a distraction from the fact that local officials here on Earth still need to make better zoning decisions.”

If most of the AI industry can eventually be powered by space, as SpaceX claims, it will require millions of sprawling new satellites, in an orbit currently dotted by fewer than 20,000 of them. Though “space is really big,” as Elon Musk has put it, one million satellites would still profoundly and, likely irrevocably, transform our night sky into one in which data centers outnumber visible stars.

“Will humanity notice if there are fewer stars in the sky? Well, not so much right now,” given light pollution in many cities, said John Barentine, an astronomer and environmental advocate for the night sky. “But what if they’re replaced by these artificial stars in the night sky? Is that the point at which people will say, ‘Wait a minute, we don’t want this. We want the benefits, but we don’t want this as a consequence.’”

This is, of course, the tension also at the heart of building data centers here on Earth. To some extent, they’re the most tangible representations of how little power we have to shape the course of a transformative new technology that few trust, and even fewer asked for. It’s one thing to object to a hulking data center, but it might be another altogether to see the sigils of our digital overlords illuminating the firmament. Would a place like Tucson, one of the most beautiful places to stargaze in the world, prefer a Project Blue to a starscape marred by blinking servers in the sky?
