U.S. officials are worried about hacking and insider theft of AI secrets, which China has denied. From a report: On a July day in 2018, Xiaolang Zhang headed to the San Jose, Calif., airport to board a flight to Beijing. He had passed the checkpoint at Terminal B when his journey was abruptly cut short by federal agents. After a tipoff by Apple's security team, the former Apple employee was arrested and charged with stealing trade secrets related to the company's autonomous-driving program. It was a skirmish in a continuing shadow war between the U.S. and China for supremacy in artificial intelligence. The two rivals are seeking any advantage to jump ahead in mastering a technology with the potential to reshape economies, geopolitics and war.

Artificial intelligence has been on the Federal Bureau of Investigation's list of critical U.S. technologies to protect, just as China placed it on a list of technologies it wanted its scientists to achieve breakthroughs on by 2025. China's AI capabilities are already believed to be formidable, but U.S. intelligence authorities have lately made new warnings beyond the threat of intellectual-property theft. Instead of just stealing trade secrets, the FBI and other agencies believe China could use AI to gather and stockpile data on Americans at a scale that was never before possible. China has been linked to a number of significant thefts of personal data over the years, and artificial intelligence could be used as an "amplifier" to support further hacking operations, FBI Director Christopher Wray said, speaking at a press conference in Silicon Valley earlier this year.

"No massive cooling towers, miles of concrete, expansive evacuation zones," writes the Washington Post, describing modular nuclear reactors instead as "space-age plants that can be small enough to fit in a large backyard," using "downsized" reactors like the ones on nuclear-powered submarines.

And America's coal country "is a ripe target for this experiment, with infrastructure that can be repurposed, capable workforces and communities eager to reclaim prominence in the energy economy." More than 300 retired and operating coal plants in the United States are good candidates for a nuclear conversion, according to a recent Department of Energy report that has touched off a frenzy of activity. Communities that previously rejected nuclear power as unsafe or a threat to the coal industry are now clamoring to be a part of what might be branded nuclear 2.0. "See that hilltop over there?" said Michael Hatfield, a former coal company engineer who is now the administrator for Wise County [in Virginia]. "If you put a nuclear plant someplace like that, it is not going to be near anybody's backyard. This would keep us in the forefront of the energy business. We see it as our future...."

It was only a year ago that nuclear power was banned in West Virginia, under a state law intended to protect the coal industry. The state is among several to either lift such a ban or pass a law encouraging development of small nuclear reactors over the last few years. Political leaders see opportunities to boost regional economies and to get a piece of the billions of dollars in subsidies for generating "advanced nuclear" power available through the recently enacted Inflation Reduction Act.... Virginia is among at least eight states pursuing a small reactor. At least another eight have launched feasibility studies, according to federal energy officials.
And back in Washington D.C. there's also high hopes for the technology: U.S. climate envoy John F. Kerry said in a recent interview with The Post that the technology's success is vital for meeting the world's goal of avoiding the most catastrophic fallout from climate change by limiting warming to 1.5 degrees Celsius.

"I don't think we get there without it," Kerry said.

The Washington Post describes it as "the next internet." Wikipedia defines it as "a collective virtual shared space...including the sum of all virtual worlds, augmented reality, and the Internet." But it was Neal Stephenson who named it "the metaverse" in his 1992 science fiction novel Snow Crash.

Are we closer to seeing it happen? The Washington Post reports: In the past month, office culture has coalesced around video chat platforms like Zoom, while personal cultural milestones like weddings and graduations are being conducted in Nintendo's Animal Crossing: New Horizons. The Metaverse not only seems realistic — it would probably be pretty useful right about now. The Metaverse reality is still years, possibly decades, away. But Epic Games CEO Tim Sweeney has been publicly pushing for its creation, and he isn't alone in his desire to push for the Metaverse, where the online world echoes and fulfills real-world needs and activities. Constructing the virtual Internet space is Silicon Valley's macro goal, many of whom are obsessed with Neal Stephenson's 1992 book, "Snow Crash," which defined the term.

In recent years, Facebook, Google and Samsung have all made heavy investments in cloud computing and virtual reality companies in anticipation of a Metaverse... But it's Epic Games, with Fortnite, that has the most viable path forward in terms of creating the Metaverse, according to an essay by venture capitalist and former Amazon executive Matthew Ball... [The article also notes other "traits" of the metaverse in Minecraft and Roblox.] The most widely agreed core attributes of a Metaverse include always being live and persistent — with both planned and spontaneous events always occurring — while at the same time providing an experience that spans and operates across platforms and the real world. A Metaverse must also have no real cap on audience, and have its own fully functioning economy... Fortnite hasn't reached Metaverse status yet. But Fortnite as a social network and impossible-to-ignore cultural phenomenon, Ball says, provides Epic Games a key advantage for leading in the Metaverse race. Fortnite draws a massive, willing and excited audience online to engage with chaotically clashing intellectual properties... "This organic evolution can't be overemphasized," Ball writes in his essay. "If you 'declared' your intent to start a Metaverse, these parties would never embrace interoperability or entrust their IP. But Fortnite has become so popular and so unique that most counterparties have no choice but to participate... Fortnite is too valuable a platform...."

The current swarm to an online-only social and capitalist economy has only highlighted the current Internet's failings, and what the Metaverse needs to do, Ball said. Big sites like Facebook, Google and Amazon continue to dominate online activity, as do larger streaming services like YouTube and Netflix. But each location requires its own membership and has separate ecosystems. "Right now, the digital world basically operates as though every restaurant and bar you go to requires a different ID card, has a different currency, requires their own dress codes and has their own units [of service and measurement]," Ball said. "It is clear that this really advantages the biggest services. People are just sticking to the big games, really. However there's a clear argument that reducing network lock-in can really raise all boats here."

Sweeney said as much in his DICE Summit keynote speech February. If the game industry wants to reshape the Internet and move away from Silicon Valley's walled gardens, Sweeney stressed that publishers need to rethink economies in the same way email was standardized... "We need to give up our attempts to each create our own private walled gardens and private monopoly and agree to work together and recognize we're all far better off if we connect our systems and grow our social graphs together.
Neal Stephenson answered questions from Slashdot readers back in 2004.

An anonymous reader writes: Academic research has been busily trying to pin down how a changing climate will affect our planet over the long- and short-term. But a new study in the journal Nature attempts to forecast not the changes in weather, but the changes in our economy as a result of climate change. "The study (abstract) finds that climate change can be expected to reshape the global economy by reducing average global incomes roughly 23 percent by the year 2100. This study is important because it solves a problem that has existed in prior models of climate change effects on economics: discrepancies between macro and micro level observations." Notably, the paper provides evidence that regional economies can be linked to global climate effects. "This modeling allowed them to examine whether country-specific deviations from growth trends were related to country-specific differences in temperature and precipitation trends, while accounting for any global shifts that would be experienced to affect all countries."
