An anonymous reader quotes a report from Ars Technica: Starting this year, the federal government will begin doling out $5 billion to states over five years to build a nationwide network of fast chargers. The plan initially focuses on the Interstate Highway System, directing states to build one charging station every 50 miles. Those stations must be capable of charging at least four EVs simultaneously at 150 kW. Once states have completed the Interstate charging network, they'll be able to apply for grants to fill in gaps elsewhere. The Joint Office of Energy and Transportation, a new agency formed to help the Transportation and Energy Departments administer the program, will allow case-by-case exceptions to the 50-mile requirement if, for example, no grid connection is available nearby.

Funding for the initial Interstate portion of the program will be allocated using a formula that mimics how federal highway grants are distributed. Starting in fiscal year 2022, $615 million will be available to build charging stations, and $300 million will be allocated to set up the Joint Office of Energy and Transportation. Ten percent of each year's funding will go toward filling gaps in the network. After the initial $5 billion program is launched, another $2.5 billion in discretionary grants will be available to build chargers in rural and underserved areas.

As part of their plans submitted to the federal government, states will need to ensure that the charging stations will be reliable -- at least one charger per station needs to be working more than 97 percent of the time -- and that they will limit their impact on the electric grid. States are also directed to design stations so they can be easily expanded and upgraded as demand grows and charging rates increase. The new program also encourages states to site chargers near travel centers, convenience stores, visitor centers, or restaurants. To get credit for their Interstate build-out, states will have to install chargers that use the Combined Charging System, also known as CCS. [...] The new program also prioritizes domestic production of chargers, which has already spurred some manufacturers to begin setting up operations in the US. Secretary of Transportation Pete Buttigieg says the agency is looking at how people will pay for charging. "Part of this program is going to be a shared standard. If we're going to use taxpayers' dollars to help private actors put in charging stations, then of course we need to make sure the citizen is getting good value out of it. There may be any number of network benefits through loyalty programs. That's fine," he said, "but we've got to make sure... everybody can benefit."

Western Digital said on Wednesday certain materials at two of its manufacturing units in Japan, operated by joint-venture partner Kioxia Holdings, were contaminated and will result in reduced availability of flash storage devices. From a report: According to the company's current assessment, there would be a shortage of at least 6.5 exabytes in flash storage availability. One exabyte equals one billion gigabytes. Western Digital is working closely with Kioxia to implement necessary measures that will restore the facilities to normal operational status as quickly as possible.

An anonymous reader quotes a report from Ars Technica: Recently, two computer scientists had an idea: if computers use energy to perform calculations, could stored data be a form of stored energy? Why not use computing as a way to store energy? What if information could be a battery, man? As it turns out, the idea isn't as far-fetched as it may sound. The "information battery" concept, fleshed out in a recent paper (PDF), would perform certain computations in advance when power is cheap -- like when the sun is shining or the wind is blowing -- and cache the results for later. The process could help data centers replace up to 30 percent of their energy use with surplus renewable power.

The beauty of the system is that it requires no specialized hardware and imposes very little overhead. "Information Batteries are designed to work with existing data centers," write authors Jennifer Switzer, a doctoral student at UC San Diego, and Barath Raghavan, an assistant professor at the University of Southern California. "Some very limited processing power is reserved for the IB [information battery] manager, which manages the scheduling of both real-time computational tasks and precomputation. A cluster of machines or VMs is designated for precomputation. The IB cache, which stores the results of these precomputations, is kept local for quick retrieval. No additional infrastructure is needed."

In the model Switzer and Raghavan created to test the concept, the IB manager queried grid operators every five minutes -- the smallest time interval the operators offered -- to check the price of power to inform its predictions. When prices dipped below a set threshold, the manager green-lit a batch of computations and cached them for later. The system was pretty effective at reducing the need for expensive "grid power," as the authors call it, even when the pre-computation engine did a relatively poor job of predicting which tasks would be needed in the near future. At just 30 percent accuracy, the manager could begin to make the most of the so-called "opportunity power" that is created when there is excess wind or solar power. In a typical large data center, workloads can be predicted around 90 minutes in advance with about 90 percent accuracy, the authors write. With a more conservative prediction window of 60 minutes, "such a data center could store 150 MWh, significantly more than most grid-scale battery-based storage projects," they say. An equivalent grid-scale battery would cost around $50 million, they note.

According to tech reporter and Apple leaker Mark Gurman, Apple is preparing to launch four M2 Macs throughout 2022. MacWorld reports: The first models will likely arrive later in the year, with the redesigned MacBook Air leading the way, followed by a new 13-inch MacBook Pro, 24-inch iMac, and entry-level Mac mini. A DigiTimes report on Tuesday said the 13-inch MacBook Pro may launch at Apple's spring event to usher in the new chip. Like 2021, Apple will be releasing Macs with several different chips in 2022. The M2 will be a successor to the M1, likely with the same 8-core design (four performance cores and four efficiency cores), and the M1 Pro and M1 Max will make their way into more high-end Macs. The first of those, the 27-inch iMac, could arrive at Apple's spring event, with a Mac mini coming later in the year. [...] There's also a new Mac Pro due in 2022 as the culmination of the Apple silicon transition. That would mean every Mac line is due for a refresh this year and nearly every model, with only the recently released 14-inch and 16-inch MacBook Pro escaping without a refresh.

A California newspaper covers "pleas" to the state's governor to delay the closure of a nuclear power plant: On Thursday, Dr. Steven Chu, former U.S. Secretary of Energy under the Obama administration and a Nobel laureate, and more than 79 scientists, academics and entrepreneurs sent a letter to [California governor] Newsom urging him to find a way to keep the plant open because of the necessary carbon-free, clean electricity it provides to the state's electricity grid. Diablo Canyon currently provides about 18,000 gigawatt-hours of clean electricity annually, comprising of about 10% of the state's electricity portfolio....

The letter was sent by the nonprofit foundation Save Clean Energy, which was organized primarily to protest the closure of the nuclear power plant.... The letter details how Diablo Canyon is critical to the state's clean energy goals, which the state is legally mandated to meet, and how it seems unlikely the state will be able to meet those goals with the plant's current scheduled decommissioning beginning in November 2024, when the first of its two Nuclear Regulatory Licenses expires.... The movement to keep Diablo Canyon nuclear power plant open has recently gained new traction after a Stanford and Massachusetts Institute of Technology report released in November claimed operating the plant for 10 years beyond its expected closure would significantly help the state meet its clean energy goals.

In a statement sent to The Tribune in December, a spokesperson for Newsom indicated the governor has no intention of delaying the closure of Diablo Canyon. "California has the technology to achieve California's clean energy goals without compromising our energy needs. The pathway is through diverse renewable energy sources, expanded energy storage and grid climate resiliency," Newsom spokesperson Erin Mellon wrote in an email to The Tribune. "Our retail energy providers are already in the process of procuring new energy projects to replace the energy produced by Diablo Canyon."

Toshiba will spend roughly 100 billion yen ($873 million) to build a power semiconductor fabrication facility in Japan, with production expected to begin by March 2025, Nikkei has learned. From the report: The new plant will be built on the grounds of Kaga Toshiba Electronics, a chipmaking subsidiary in Ishikawa Prefecture. Toshiba aims to meet the rise in demand for power chips -- used in automobiles, servers and industrial equipment -- that save energy and contribute to lower carbon emissions. All of the production equipment will be compatible with large 300 mm wafers. Compared with a 200 mm wafer conventionally used for power chips, one 300 mm wafer can produce more chips and boost production efficiency. Kaga Toshiba is also installing a 300 mm wafer production line at one of its existing buildings. The line is expected to begin operation between October 2022 and March 2023. Toshiba's investment for these endeavors totals around 130 billion yen. The 300 mm production lines to be installed in the old and new buildings will more than double the Japanese group's power-chip production capacity.

An anonymous reader quotes a report from Ars Technica: Most companies still haven't shifted their entire NVMe SSD lineups to use PCI Express 4.0, but PCIe 5.0 SSDs for PCs are already on the horizon. Storage company Silicon Motion said in a recent earnings call that it expects its PCIe 5.0-capable SSD controllers for consumer SSDs will be available sometime in 2024, opening the door to a wide variety of high-performance drives from different manufacturers. SSD manufacturer ADATA teased some PCIe 5.0 SSDs at CES last month (albeit without an expected release date), boasting of read speeds up to 14GB/s and write speeds of up to 12GB/s using a Silicon Motion SM2508 controller. Current high-end PCIe 4.0 SSDs like Samsung's 980 Pro top out at roughly half those speeds.

Other reports have suggested that these PCIe 5.0 consumer SSDs are coming later in 2022, but according to the call transcript, that only applies to the latest version of Silicon Motion's PCIe 5.0 controller for enterprise SSDs -- the products that end up in servers and data centers, not what typically ends up in the PC on your desk or lap. Early PCIe 4.0 SSDs for consumer PCs were also demonstrated at CES a couple of years before they became products that you could actually buy. For 2022 and 2023, Silicon Motion will continue to focus on those PCIe 4.0 SSDs. Budget SSDs like Western Digital's WD Black SN770 SE are only beginning to transition to PCIe 4.0, and according to reviews like this one from Tom's Hardware, their controllers and flash memory aren't yet fast enough to benefit much from the extra bandwidth. Silicon Motion also says that PCIe 4.0 SSDs have only become common in pre-built PCs within the last year because of "extensive verification and testing" requirements.

An anonymous reader quotes a report from Phys.Org: A team of researchers from the University of Massachusetts Amherst recently announced in the Proceedings of the National Academy of Sciences that they had engineered a new rubber-like solid substance that has surprising qualities. It can absorb and release very large quantities of energy. And it is programmable. Taken together, this new material holds great promise for a very wide array of applications, from enabling robots to have more power without using additional energy, to new helmets and protective materials that can dissipate energy much more quickly.

"Imagine a rubber band," says Alfred Crosby, professor of polymer science and engineering at UMass Amherst and the paper's senior author. "You pull it back, and when you let it go, it flies across the room. Now imagine a super rubber band. When you stretch it past a certain point, you activate extra energy stored in the material. When you let this rubber band go, it flies for a mile." This hypothetical rubber band is made out of a new metamaterial -- a substance engineered to have a property not found in naturally occurring materials -- that combines an elastic, rubber-like substance with tiny magnets embedded in it. This new "elasto-magnetic" material takes advantage of a physical property known as a phase shift to greatly amplify the amount of energy the material can release or absorb.

A phase shift occurs when a material moves from one state to another: think of water turning into steam or liquid concrete hardening into a sidewalk. Whenever a material shifts its phase, energy is either released or absorbed. And phase shifts aren't just limited to changes between liquid, solid and gaseous states -- a shift can occur from one solid phase to another. A phase shift that releases energy can be harnessed as a power source, but getting enough energy has always been the difficult part. "To amplify energy release or absorption, you have to engineer a new structure at the molecular or even atomic level," says Crosby. However, this is challenging to do and even more difficult to do in a predictable way. But by using metamaterials, Crosby says that "we have overcome these challenges, and have not only made new materials, but also developed the design algorithms that allow these materials to be programmed with specific responses, making them predictable."

In a tech world still hindered by component shortages, choices have to be made. And in the world of laptops, it seems that choice is Windows-based devices over those running Chrome OS. From a report: IDC on Monday released early data from its latest Worldwide Quarterly Personal Computing Device Tracker. It pointed to a sharp 63.6 percent decline in Chromebook shipments, which the IDC defines as "shipments to distribution channels or end users, in Q4 2021 (4.8 million shipments) compared to Q4 2020 with (13.1 million shipments)." In addition to market saturation, supply issues also hurt Chromebook shipments, as the industry still struggles with a deficit of PC components, from CPUs to integrated circuits for Wi-Fi modules and power management. "Supply has also been unusually tight for Chromebooks as component shortages have led vendors to prioritize Windows machines due to their higher price tags, further suppressing Chromebook shipments on a global scale," Jitesh Ubrani, research manager with IDC's Mobility and Consumer Device Trackers, said in a statement accompanying Monday's announcement.

Backblaze, a cloud storage service that's been running hundreds of thousands of storage drives to keep an eye on reliability, has issued its latest report. ZDNet summarizes the major findings: Over 2021, Backblaze added 40,460 hard drives to its pool of drives, making a total of 206,928 drives in total. Of thee, 3,760 are boot drives and 203,168 are data drives. There's a lot of information in the report to look at, but there are two standout parts from the report:

- The oldest drive is the most reliable: 6TB Seagate drives (model: ST6000DX000) have an average age of 80.4 months (almost seven years) yet incredibly these also have the lowest annualized failure rate (AFR) of 0.11 percent.
- Newer drives are also doing really well: 16TB WDC drives (model: WUH721816ALE6L0) and 16TB Toshiba drives (model: MG08ACA16TE) were both added in 2021, and have an AFR of 0.14 and 0.91 percent, respectively.

Backblaze had also been experiencing problems with the 14TB Seagate drives (model: ST14000NM0138) in its Dell storage servers. It seems that following a firmware update the reliability of these drives has improved dramatically. Further reading: Seagate HDDs Top and Bottom Backblaze's 2021 Failure Rates Data (Tom's Hardware)

According to Chinese news outlet Sina, BOE has made breakthroughs in monitor technology and has built the world's first 500 Hz gaming monitor. Tom's Hardware reports: The monitor features a 27-inch, Full HD panel equipped with a high-mobility oxide backplane which is how BOE achieved the blisteringly high refresh rate, with a response time of just 1ms. BOE has ample experience with oxide semiconductor display technology. For example, the company's 500 Hz monitor is significantly faster than the fastest gaming monitors on the market today, from the likes of Asus, Alienware, and Acer, which "only" top out at 360 Hz. Other attributes include accurate 8-bit output and support for an 8-lane eDP signal. Remember that BOE's monitor is a prototype designed for demonstration purposes only. BOE has not stated if it will be making a 500 Hz gaming panel for the mass market anytime soon, so we could be waiting a long until an official monitor arrives in the hands of gamers.

A Charlotte, North Carolina man has pleaded guilty to charges of mail fraud after stealing and reselling merchandise from an Amazon warehouse, the Department of Justice said in a news release. The Verge reports: Between June 2020 and September 2021, Douglas Wright, Jr., an operations manager at Amazon's Charlotte warehouse, allegedly stole products with a total value of more than $273,000, using his access to get computer parts like internal hard drives and processors, according to the DOJ. Wright said in court on Friday that he shipped the products to his home, then sold them to a computer wholesale company in California. He faces a maximum sentence of 20 years in prison and a $250,000 fine. A sentencing date has not been set.

Ohio promised Intel roughly $2 billion in tax breaks and incentives to attract its $20 billion chip-making factory to the state, according to the Associated Press. The state's development director tells them it may be the biggest economic development deal in history.

Intel's hoping it creates a powerful new technology hub in the Midwest, while also eventually addressing an ongoing chip shortage, according to the article. Unfortunately, the factory's production isn't expected to come online until 2025, though "The complex could grow much larger and more quickly, Intel executives said, if Congress approves a $52 billion bill that would invest in the chip sector and help ensure more production in the U.S." Intel CEO Patrick Gelsinger said the total Ohio investment could top $100 billion over the decade, with six additional factories, making it one of the world's biggest chipmaking sites....

Ohio's offer includes $600 million to help Intel offset the cost of building the factories, which is more expensive than it would be in Asia, said Lydia Mihalik, the state's development director. The state also will pay nearly $700 million for roadwork and water infrastructure upgrades, including a system that will allow the plant to reuse wastewater. The state Legislature this summer approved a 30-year tax break that will allow Intel to save $650 million.

The state's share will be money well spent because the Intel facility will not only create jobs, but also make Ohio more attractive to industries such as auto, aviation and defense that rely on chips, Mihalik said. "These investments will not only ensure that this project is successful here, but will also be supporting the region by increasing local infrastructure to support future growth," Mihalik said.
The article also cites the Semiconductor Industry Association's estimate that America's share of the world's chip manufacturing has declined from 37% in 1990 to 12% today.

"Intel will have to defend itself against claims that the semiconductor goliath knew its microprocessors were defective and failed to tell customers," reports the Register: On Wednesday, Judge Michael Simon, of the US District Court of Oregon, partially denied the tech giant's motion to dismiss a class-action lawsuit arising from the 2018 public disclosure of Meltdown and Spectre, the family of data-leaking chip microarchitecture design blunders....

To defend against Meltdown and Spectre, Intel and other affected vendors have had to add software and hardware mitigations that for some workloads make patched processors mildly to significantly slower. The disclosure of related flaws has continued since that time, as researchers develop variations on the initial attacks and find other parts of chips that similarly expose privileged data. It is a problem that still is not entirely solved...

[L]awsuits have been consolidated into a multi-district proceeding known as "Intel Corp. CPU Marketing, Sales Practices and Products Liability Litigation" (3:18-md-02828-SI). And since 2018, Intel has been trying to get them to go away. Twice before the judge had dismissed the plaintiffs' complaint while allowing the plaintiffs to amend and refile their allegations. This third time, the judge only partially granted Intel's motion to toss the case. Judge Simon dismissed claims based on purchases up through August 2017 because Intel was unaware of the microarchitecture vulnerabilities up to that point. But he allowed seven claims, from September 2017 onward, to proceed, finding the plaintiffs' contention that Intel delayed disclosure of the flaws to maximize holiday season sales plausible enough to allow the case to move forward.

"Based on plaintiffs' allegations, it is not clear that Intel had a countervailing business interest other than profit for delaying disclosure for as long as it did (through the holiday season), for downplaying the negative effects of the mitigation, for suppressing the effects of the mitigation, and for continuing to embargo further security exploits that affect only Intel processors," the judge wrote in his order.

The Toronto Star just published a searing excerpt from the book Cobalt: Cradle of the Demon Metals, Birth of a Mining Superpower — written by a member of Canada's Parliament: It argues in part that "The social conflict that existed in the early days of Cobalt has been magnified a thousandfold in jurisdictions where the rule of law is compromised, and incursions into Indigenous territories heighten conflict." The world is searching for cobalt, the miracle ingredient of the digital age. The metal's capacity to store energy and stabilize conductors has made possible the proliferation of rechargeable batteries, smartphones and laptops. More crucially, in the face of catastrophic climate change, cobalt offers the hope of a clean-energy future. But cobalt has a much darker side. The relentless drive to feed the cobalt needs of Silicon Valley has led to appalling levels of degradation, child abuse and environmental damage in the Democratic Republic of Congo (DRC), the world's number one cobalt producer. The situation is so dire that human rights campaigners have denounced cobalt as the blood mineral of the 21st century.

In the 21st century, Canada's relationship to its resource extraction sector is coming under increasing scrutiny as we contemplate a world of melting ice and burning forests. So what can the story of Cobalt teach us in an age of pandemic, impending climate catastrophe, racial division and class strife? It may be that the shape-shifting metal will prove to be the miracle ingredient that leads us to a more sustainable way of life. Or it may be that we need to find a less rapacious balance between environment, social justice, human rights and the world's depleting resources.
The article points out that big tech companies "would love to cut their ties with the abuses in the Democratic Republic of Congo, but cobalt is an extremely elusive metal, and the struggle to secure cobalt supplies is taking place within the context of a much broader geopolitical struggle with China."

CBS News reports that foreign cyberattackers aren't the only potential threat to America's electrical power grid: Domestic violent extremists have been planning to try to disrupt the U.S. power grid and will probably keep doing so, according to a Department of Homeland Security intelligence bulletin shared with law enforcement agencies and utility operators Monday and obtained by CBS News. "Domestic violent extremists have developed credible, specific plans to attack electricity infrastructure since at least 2020, identifying the electric grid as a particularly attractive target given its interdependency with other infrastructure sectors," the bulletin reads. It warns that extremists "adhering to a range of ideologies will likely continue to plot and encourage physical attacks against electrical infrastructure."

Still, the bulletin notes that, "Absent significant technical knowledge or insider assistance, small scale attacks are unlikely to cause widespread, multi-state power loss but may result in physical damage that poses risks to operations or personnel."

"Former heads of nuclear regulatory bodies across Europe and the US put out a statement this week voicing their opposition to nuclear energy as a climate solution," reports The Verge's Justine Calma. The publication spoke with Gregory Jaczko, former chairman of the US Nuclear Regulatory Commission, to learn more about why some nuclear experts oppose the energy source as a climate fix. Slashdot reader Ol Olsoc shares an excerpt of the interview: Former NRC Chair Gregory Jaczko in an interview with the Verge notes: "I think there's been a lot of misinformation about the role that nuclear power can play in any climate strategy. A lot of attention has been put on nuclear as somehow the technology that's going to solve a lot of problems when it comes to dealing with climate change. I just think that's not true. And it's taking the debate and discussion away from the areas that can have a role and that do need focus and attention." He added: "I think it's money that's not well spent. Nuclear has shown time and time again that it cannot deliver on promises about deployment and costs. And that's really the most important factor when it comes to climate." Jaczko goes on to note how many of the nuclear plants when he was chairman were supposed to come online but have experienced delays and exceptional cost overruns. Two of the four new design reactors that were licensed when he was chairman, which were supposed to be starting production in 2016 and 2017, were canceled, "and that involved federal indictments for fraud among the heads of the company running that reactor development." The other two, he says, "continue to be pushed back and now are scheduled to start in 2022 or 2023" with a price tag that's over $30 billion.

If you're using either Dropbox or Microsoft OneDrive to sync files on a Mac, you'll want to pay attention to the release notes for today's macOS 12.3 beta: the update is deprecating a kernel extension used by both apps to download files on demand. Ars Technica reports: The extension means that files are available when you need them but don't take up space on your disk when you don't. Apple says that "both service providers have replacements for this functionality currently in beta." Both Microsoft and Dropbox started alerting users to this change before the macOS beta even dropped. Dropbox's page is relatively sparse. The page notifies users that Dropbox's online-only file functionality will break in macOS 12.3 and that a beta version of the Dropbox client with a fix will be released in March.

Microsoft's documentation for OneDrive's Files On-Demand feature is more detailed. It explains that Microsoft will be using Apple's File Provider extensions for future OneDrive versions, that the new Files On-Demand feature will be on by default, and that Files On-Demand will be supported in macOS 12.1 and later.

In addition to integrating better with the Finder (also explained by Microsoft here), using modern Apple extensions should reduce the number of obnoxious permission requests each app generates. The extensions should also reduce the likelihood that a buggy or compromised kernel extension can expose your data or damage your system. But the move will also make those apps a bit less flexible -- Microsoft says that the new version of Files On-Demand can't be disabled. That might be confusing if you expect to have a full copy of your data saved to your disk even when you're offline.

MattSparkes shares a report from New Scientist: Quantum computers would need to become around one million times larger than they are today in order to break the SHA-256 algorithm that secures bitcoin, which would put the cryptocurrency at risk from hackers. Breaking this impenetrable code is essentially impossible for ordinary computers, but quantum computers, which can exploit the properties of quantum physics to speed up some calculations, could theoretically crack it open.

[Mark Webber at the University of Sussex, UK, and his colleagues] calculated that breaking bitcoin's encryption in this 10 minute window would require a quantum computer with 1.9 billion qubits, while cracking it in an hour would require a machine with 317 million qubits. Even allowing for a whole day, this figure only drops to 13 million qubits. This is reassuring news for bitcoin owners because current machines have only a tiny fraction of this -- IBM's record-breaking superconducting quantum computer has only 127 qubits, so devices would need to become a million times larger to threaten the cryptocurrency, something Webber says is unlikely to happen for a decade. The study has been published in the journal AVS Quantum Science.

Manufacturers and other buyers of computer chips had less than five days' supply of some chips on hand late last year, leaving them vulnerable to any disruptions in deliveries, the Commerce Department reported Tuesday as it pushed Congress to endorse federal aid for chip makers. The Washington Post reports: Manufacturers' median chip inventory levels have plummeted from about 40 days' supply in 2019 to less than five days, according to a survey of 150 companies worldwide that the Commerce Department conducted in September. "This means a disruption overseas, which might shut down a semiconductor plant for 2-3 weeks, has the potential to disable a manufacturing facility and furlough workers in the United States if that facility only has 3-5 days of inventory," the Commerce Department concluded in a six-page summary of its findings.

The lack of chip inventory leaves auto manufacturers and other chip users with "no room for error," Commerce Secretary Gina Raimondo said Tuesday as she presented the findings. "A covid outbreak, a storm, a natural disaster, political instability, problem with equipment -- really anything that disrupts a [chip-making] facility anywhere in the world, we will feel the ramifications here in the United States of America," she said. "A covid outbreak in Malaysia has the potential to shut down a manufacturing facility in America."

"The reality is Congress must act," Raimondo added, urging lawmakers to pass a proposal for $52 billion in federal subsidies to incentivize construction of chip factories. "Every day we wait, we fall further behind." The Senate passed the measure last year. The legislation has been tied up for months in the House, though House Democrats are expected to introduce their version of the legislation as soon as this week. Industry executives say federal funding is likely to create more long-term supply of chips but not to alleviate the short-term shortages because chip factories take years to build.
