I’ve been running a little experiment the past 10 days.
I carried two phones everywhere: my Google Fi device and my GrapheneOS device.
Every night, here’s how the batteries compared:
• Google Fi: about 5% left
• GrapheneOS: about 50–75% left
What’s going on here? Am I really using the Google Fi phone 2–4x more?
Actually it’s the opposite.
My GrapheneOS phone is my daily driver. That’s where I use Signal, Brave, podcasts, audiobooks, email, camera, notes, calendar, my language app, and other things.
Meanwhile, on my Google Fi phone, I’ve installed exactly two apps: Signal and Google Maps, and I also use it as an internet hotspot. I deleted as many preinstalled apps as I could without breaking the phone, but there are countless ones I can’t remove.
At first glance you might think the hotspot is what’s draining the battery. That’s certainly a factor, but for context I turn the device to airplane mode (and shutting off the hotspot) whenever I’m not using it.
Even with “aggressive battery saver” enabled and hours in airplane mode, the Google phone churned through its battery like crazy.
The fact that the Google phone’s battery still dies so quickly is revealing. Battery drain can actually be a useful indicator of how private your device is. Some of this comes down to deliberate privacy choices, and some of it comes from the inherent design of each operating system.
Why battery drain is a privacy clue
Battery life is a rough but useful proxy for what’s happening under the hood.
If your phone is dead by dinnertime even when you barely use it, something else is doing the work. And “something else” usually means:
• Background services constantly phoning home
• Analytics trackers collecting usage data
• System-level apps pinging servers even when you think they’re off
• Push notification frameworks that keep connections alive 24/7
That invisible activity not only kills your battery, it shows how much your phone is reporting back without your consent.
Your privacy choices also matter
The way I use my devices also makes a huge impact on how much background activity is happening.
On Graphene, I silo apps across six profiles. My main profile has all the functionality I mentioned before. And I’m constantly using the device, but a lot of what I do doesn’t require connectivity. I can take pictures, listen to music, write notes, and listen to audiobooks all without needing to be online.
When I want to check messages, email, or browse the internet, I simply turn WiFi on, and when I’m done I turn it off again (like turning off a light switch when I leave a room).
I also have other apps I rarely use, some of which are more privacy-invasive, like Uber or others that require sandboxed Google Play Services. These are kept in secondary profiles, and when those profiles are inactive, they’re effectively powered off. This means there’s no chance of these apps running in the background.
Meanwhile, on the Google Fi phone, even though I tried to delete as much bloatware as possible, there are countless apps I can’t uninstall and processes I can’t turn off.
Google Play Services is the biggest offender: It’s a hugely invasive process with elevated system permissions that is always on. You can think of it as a hidden operating system layered on top of Android, handling push notifications, location data, updates, and telemetry. It’s not optional.
In some cases it can actually make your battery more efficient by centralizing notifications instead of having each app run its own system. But that depends entirely on how you use your device.
For example, I don’t have a ton of apps on that device that need all their processes to be centralized in a single, more efficient system. I just have 2 apps.
And I don’t use notifications at all, which means that the centralization of push notification services isn’t helpful to me. And even if I did use notifications, Signal is capable of handling its own push notifications without Google Play Services. So for my setup, having Play Services constantly pinging servers and running countless background processes is overkill. It makes a data-minimalist setup impossible.
Why GrapheneOS performs differently
Unlike most Android phones, and especially Google Fi, GrapheneOS doesn’t come with bloatware. It doesn’t have the same preinstalled junk running in the background -- it’s an incredibly stripped down OS. If you want Google play services you can install it, but it’s sandboxed just like any other app, without elevated permissions. That means it doesn’t get special system access to spy on everything you do like it does on Android.
On top of that, GrapheneOS lets you isolate apps into separate profiles, each with its own encryption key and background permissions. Apps in one profile can’t see or interact with apps in another.
This not only improves security, it massively reduces unnecessary background chatter. Most of the Graphene phone spends its day idle, instead of phoning home.
Background activity = surveillance
This comparison proved to me that even on a pared-down Google phone with limited use, there are countless processes running behind the scenes that I don’t control and don’t need.
And those processes make a huge difference in how fast the battery disappears.
Other phones show the same pattern
I compared my results with others in my travel group. Their iPhones drained quickly too, even with moderate use. Apple is better than Android on privacy, but iPhones are still packed with system services constantly talking to Apple and 3rd party servers. Background iCloud sync, location lookups, telemetry reporting, Siri analytics etc all adds up.
In short: if your phone battery is always gasping for air, it’s because it’s working for someone else.
Battery life is a window into privacy. If your phone is constantly trying to talk to servers you didn’t ask it to, it’s both:
Bad for your battery
Bad for your privacy
Why this matters
When I travel, I want peace of mind that my phone won’t die halfway through the day. But even more than that, I want confidence that it isn’t secretly working for someone else.
I don’t pretend to know every technical reason that Google Fi and Apple drain so fast, but I do know that I have far less control over their processes than I do on Graphene. On Graphene, I can granularly control which apps access the internet, I can eliminate Google Play Services entirely, I can block apps from accessing sensors they don’t need. I can essentially be a data minimalist, while still having all the connectivity I want on the go.
And the difference in performance is stark. My Graphene phone lasts all day, even with heavy use. It’s calm, efficient, and private. The others are invasive, have hidden connections, and more background processes.
Battery life and privacy are more connected that we might realize, and GrapheneOS is winning on both. It’s another reason why switching to Graphene was one of my favorite privacy choices I’ve ever made.

This week marks the 55th anniversary of the Bank Secrecy Act (BSA), a pivotal law that set us on the road to total financial surveillance. Last week I wrote about ways in which the Patriot Act eroded financial privacy, but the modern shift really began in 1970 with the BSA. Since its introduction, the BSA regime has grown staggeringly, and now touches basically every corner of the financial system. Financial privacy used to be assumed, but today the norm has flipped, and pervasive monitoring is treated as ordinary.
Let’s look back over five decades to see what changed, how much privacy we lost, and how this new baseline of surveillance became "just the way things are".
It appears that the collective memory has faded. We’ve forgotten that just a few decades ago, withdrawing one’s own funds was a straightforward right. There were no probing questions about the intended use of those funds or one’s occupation. The routine sharing of bulk transaction data with countless third parties was not the standard.
Today is a different story. We are required to justify our routine financial activities, authenticate our identity, and defend our choices at every financial turn. There has never been so much friction between us and our own money, with surveillance hurdles at every juncture just to pay for something online, and this new normal is an ingrained part of our expectations of using the financial ecosystem.
On top of that, behind the scenes, data pipelines spray a firehose of personal information to countless invisible players, and the data gets cycled from institutions, to brokers, to government entities, and back the other way.
How individuals interacted with the financial system 55 years ago versus today is night and day. Times really have changed, but they changed slowly, with a lot of these changes creeping in behind the scenes before the public ever realized what was going on.
The great privacy paradox
So we’ve established that financial privacy has never been worse. But here’s the confusing part about the situation: many people still go about their daily lives behaving as if what they do just stays between them and their bank, or between them and a given merchant.
A paradoxical situation has emerged, where most people continue to believe in a notion of financial privacy that has ceased to exist.
This widespread assumption that financial activities remain confidential, safeguarded by banks or credit unions, contrasts starkly with reality. In truth, financial privacy in the United States is more illusory than real.
How do we explain this mismatch between what people believe is true and the actual state of financial privacy?
First, privacy was the standard for so long, and then the systematic dismantling of our financial privacy occurred gradually over time without people really paying attention.
Second, the bulk of this increased surveillance has been intentionally kept hidden from the public.
This is the most insidious part of the situation, which I want to make very clear in this newsletter. The privacy we think we have and the privacy we actually have are very different things. Governments and banks would never have been able to get away with this shift if they hadn’t deliberately kept it out of view.
To explore the history of how financial privacy slowly disappeared, and to unveil the extensive financial surveillance apparatus that remains largely opaque to the general public, we have to go back through history and look carefully at how all of this surveillance crept in.
This analysis primarily focuses on developments within the United States, but the implications are global, thanks to the U.S. exporting its legislative and regulatory frameworks abroad. The trend toward financial surveillance is worldwide, with governments now monitoring payment systems across borders.
Where it all started
The year 1970 heralded a transformative period in financial privacy with the enactment of the Bank Secrecy Act. Its aim was to address concerns over secret foreign bank accounts by gathering more information on people’s financial activities, in order to combat the concealment of wealth in overseas accounts.
The BSA introduced a paradigm shift by requiring financial institutions to maintain records of customers’ transactions and personal information and to report significant transactions, specifically those exceeding $10,000, to the Treasury Department. This legislative move transformed financial professionals into de facto government informants, reporting on Americans for the mere act of engaging with their finances.
The law sparked considerable debate, drawing criticism from various quarters, including Congress, the banking sector, and civil liberties organizations. The New York Times even reported at the time that the law was unconstitutional. A legal challenge ensued, questioning the BSA’s compatibility with the First, Fourth, and Fifth Amendments.
Central to the legal debate was the Fourth Amendment, which safeguards individuals against unreasonable searches. The mandate for financial institutions to divulge personal financial information without a warrant was perceived as an infringement of this constitutional protection.
Despite these concerns, the Supreme Court ultimately upheld the BSA, reasoning that information shared with banks constitutes business records rather than private data, thus not warranting the same expectation of privacy. This completely undermined the expectation of privacy that people had always had with their banks.
The Supreme Court at the time commented that the reporting requirements for the banks were not an undue burden, because they applied only to “abnormally large transactions.” $10,000 in 1970 was indeed seen as abnormally large, because the purchasing power of the U.S. dollar was so much higher back then.
To put this amount in context, in 1970 $10,000 would buy you a new house in some areas. From this perspective, if you were paying all cash for an entire, brand new house, it might be a suspicious enough and rare enough occurrence that it was not seen as a burden on financial institutions to report this, nor an unreasonable intrusion into people’s daily lives.
However, the BSA never included any adjustment for inflation. Year after year, the purchasing power of the US dollar disappears, which means that this financial surveillance has silently and insidiously crept further and further into our lives. Now this threshold has extended into everyday transactions.
Since 1970, the Bank Secrecy Act’s powers have not only expanded silently through inflation but explicitly through all kinds of amendments that increase its scope.
The Annunzio-Wylie Anti-Money Laundering Act
One subsequent expansion of the BSA worth noting was the Annunzio-Wylie Anti-Money Laundering Act of 1992. It broadened the scope of reportable activities through the introduction of Suspicious Activity Reports (SARs). This shift from reporting threshold-based transactions (of $10,000 or more) to any transaction considered “suspicious,” regardless of size, opened the floodgates to a firehose of financial reporting.
Another big change that the Annunzio-Wylie Anti–Money Laundering Act ushered in was around transparency of these surveillance programs. When the Bank Secrecy Act was first introduced, it was countered with something called the Right to Financial Privacy Act, that essentially said that if people’s finances are being looked into, they at least need to be told about it, and that way individuals would have the right to push back and hold overreaching entities accountable if they felt their rights were being violated.
The 1992 Annunzio-Wylie Anti–Money Laundering Act made it illegal for your bank to tell you if it filed a SAR. To this day, you’re not allowed to know if your bank filed a report to the government for you using your own money.
It also introduced “safe harbors” for banks who share information with law enforcement: under the Annunzio-Wylie Anti–Money Laundering Act banks can’t be sued or held liable for giving data to law enforcement. There were no longer repercussions, or accountability measures to protect citizens against overreach of reporting.
This really ushered in a new era of mass surveillance of the financial activity of innocent Americans. The banking sector’s role has evolved from safeguarding depositor privacy to facilitating government surveillance. It’s also a major reason why people have this illusion of financial privacy. They just don’t realize what’s been happening, by design, because the whole surveillance process has been made confidential.
The Patriot Act
Last week I did a deep dive into the Patriot Act and how it was a watershed moment for financial surveillance, but I’ll provide a quick recap of some of the major changes. Basically, the Patriot Act was the Bank Secrecy Act on steroids. Title III of the Patriot Act, The International Money Laundering Abatement and Financial Anti-Terrorism Act of 2001, aggressively cemented financial surveillance as a normalized part of everyday life.
First was the formalization of “Know Your Customer” (KYC) regulations, which have since become a staple in the arsenal of financial surveillance tools.
Before 2001, banks and institutions determined their own risk tolerance, and what customer information they needed to collect. The Patriot Act introduced minimum ID standards. It enforced a Customer Identification Program (CIP) for every bank, broker-dealers, mutual funds, and other similar institute in the US. These entities had to collect and verify government-issued IDs for every customer. They also had to cross-check identities against government watchlists.
This is when financial anonymity became illegal.
The Patriot Act also allowed unprecedented data sharing across agencies and borders. There used to be stringent rules about which government departments are allowed to share data with each other, again to protect citizens from overreach. Sections 351 and 358 broke down specific information-sharing barriers between the FBI, CIA, NSA, FinCEN, and foreign governments.
The Patriot Act also expanded safe harbor laws and allowed banking information to be shared with intelligence agencies. Mass data pipelines from private banks to the surveillance state were legalized overnight. Banks were encouraged to proactively share customer data with intelligence, without fear of being sued by the customer because they would have legal immunity.
It covered liability under “any contract or other legally enforceable agreement.” So if you had a contract with your bank that they’d keep your information private, the government said the bank now had immunity if they shared that information and broke the contract.
The intent of The Fourth Amendment was to stop the government getting your information without a warrant. But right now we have a system where the government has mandated that banks collect this information of their behalf, demanded they hand over the information, and then granted the banks legal immunity for this sharing or data, even if doing so broke “any contract or other legally enforceable agreement” of privacy between you and your bank.
On top of this, Section 314(b) created a safe harbor for financial institutions to share customer and activity information with other financial institutions, when they in good faith suspect money laundering or terrorist financing. It unleashed a torrent of data sharing, all legally protected.
Banks were now both required to report SARs and other information to the government, and they were legally shielded for aggressively and proactively doing so, and were also allowed to exchange intelligence with other banks. It fueled the private-sector surveillance grid that we have today, and deputized the financial system as investigatory agents in it.
The relationship between banks and Intelligence agencies was also formalized and made permanent. For example, it introduced something called government “broadcast lookups” where FinCEN can blast a query to thousands of financial institutions, and and banks must search their records quickly and report back. This shifted the relationship from passive reporting, to creating on-demand, system-wide queries, where banks have been deputized as active responders and participants.
Under the Patriot Act, FinCEN’s mission was also codified as financial intelligence, giving it a permanent mandate and making it a statutory intel hub.
The result is a permanent, legally protected data flow where financial institutions are effectively deputized, and customer information moves quickly to law enforcement and intelligence agencies.
Furthermore, we were told the Patriot Act would be a temporary measure, but it ended up lasting forever.
Omnibus bills for creeping surveillance
The trend of utilizing omnibus bills to quietly introduce or expand surveillance measures is ongoing. The American Rescue Plan Act of 2021, another omnibus bill, introduced surveillance to anything involving a payment transmitter (for example, PayPal, Venmo, or Cash App) that has $600 or more of transactions in a year.
In 2022, Congress floated the Special Measures to Fight Modern Threats Act, which aimed to eliminate some of the checks and balances placed on the Treasury. The Treasury Secretary has a special ability to sanction transactions and because this is such a powerful tool, there’s always been a check on this power — The Treasury Secretary has to report every time they do this in the Federal Register. The Fight Modern Threats Act tried to remove this reporting requirement, which would allow the Treasury to use these powers even more.
This bill hasn’t been passed, but it also hasn’t gone away either. Similar ideas keep resurfacing while Treasury continues to use existing Section 311 authorities through fresh 2025 actions.
There is an ongoing onslaught of bills that try to expand financial surveillance, and each time another one slips by, financial privacy in our lives is chiseled further and further away. It’s an offensive attack on the privacy expectations of innocent Americans.
Financial surveillance at the border
In September 2025, the Treasury’s Financial Crimes Enforcement Network (FinCEN) renewed and expanded a Geographic Targeting Order (GTO) that dramatically lowers the reporting threshold for cash transactions in certain areas, from $10,000 to transactions as low as $1,000.
This means that thousands of routine financial activities, like cashing a check or sending money to family, are now tracked and reported to federal authorities. The order compels businesses to collect personal information, file detailed reports, and retain records for five years.
Several lawsuits brought by the Institute for Justice have won preliminary injunctions, arguing that the GTO is unconstitutional, burdensome, and offers no proven crime-fighting benefit. Despite those court rulings, the government has appealed and continues to enforce the order in most affected areas.
CBDCs
The worst may be yet to come. Across the world, government officials have been increasingly considering central bank digital currencies, or CBDCs. A CBDC is a national currency that is a direct, digital liability of the central bank. You can think of it as a digital form of the dollar, but it’s much more than that. It would put the government in the middle of every financial transaction.
Rather than having to get our financial information from banks, the government would have access to every transaction directly. While right now, cash still affords people a private means of payment, a CBDC would eventually take the place of digital cash and eliminate that final privacy safeguard.
Furthermore, CBDCs aren’t just a digital form of money. They represent what’s known as programmable money. Rules can be coded directly into the money itself, dictating how it can be used. Money could instantly be frozen, savings seized, or certain transactions could automatically be prohibited according to predetermined rules about how money is allowed to move. Politicians are already salivating over such potential use cases.
It’s possible that the government could even do things like erase money that’s not spent fast enough, if they wanted to stimulate the economy.
Unfortunately, CBDCs are not simply theoretical. Basically every country in the world is currently exploring them. You can take a look at the Human Rights Foundation’s CBDC Tracker to see exactly where each country stands, and who has already launched one.
Those who champion CBDCs talk about how it will make our financial system more efficient, and bring it into the new age. Attention is focused on the shiny rhetoric, while yet another financial surveillance tool is slipped silently into our lives, making financial freedom just that little bit harder.
The cost of a zero-crime society
The legislative journey from the Bank Secrecy Act to the present day reflects a steady expansion of financial surveillance, driven by various rationales from combating crime to national security. When you erode financial privacy, critical questions need to be raised about the balance between security measures and individual rights.
Namely, to what extent should we as a society permit pervasive surveillance in the name of stopping crime?
To answer this question, it’s important to first recognize that the optimal crime rate is not zero. It’s a spicy take, but stick with me.
While a world with zero crime may intuitively seem better than a world with some crime, it depends on the costs of getting to that zero-crime world. We can’t bring the world to a halt to stop someone jaywalking, because the cost is too high. You can’t burn down a city to stop someone stealing a pack of gum. The cost is just too high.
We as a society need to have a conversation about which costs we’re willing to bear, and the balance we want between surveillance and privacy.
Traditionally that balance has been the Constitution, and in particular the Fourth Amendment. But the Fourth Amendment has been decimated in the digital age, and we’ve lost sight of that original Schelling point. We’ve tipped the balance scales in the complete opposite direction of the individual by stripping people of their right to privacy and allowing omnipotent surveillance of every financial activity, in the name of stopping anyone from ever committing a crime. And this cost is far too high.
Privacy is essential for a free society. If you eliminate this very thing that makes a free society possible, no matter what righteous cause you profess to be advancing, it’s a cost we can’t afford to bear.
It’s through surveillance that our freedoms are limited. Every totalitarian regime in existence maintained power through pervasive surveillance. Our financial activities reveal intimate details about us, including our religious beliefs, daily habits, and the causes we support that might hold powerful people accountable or challenge political authority.
Without financial privacy, all of these aspects become vulnerable to exploitation, and those involved are susceptible to being targeted. We must be vigilant against creeping surveillance that shifts the balance of power away from the individual.
And don’t get me wrong, removing the mass-surveillance apparatus we’ve created doesn’t mean ending the fight on crime. It just means respecting Fourth Amendment protections. If the government wants your information, they can get a warrant and prove probable cause. It’s not supposed to be absurdly easy for the government to dive into people’s private information. The purpose of the Constitution is to restrict the powers of government and protect the people.
Yet over the past few decades, we have slowly built a system of unchecked financial surveillance that makes it trivial for the government to search your affairs with impunity, and with almost no oversight or accountability. It’s time to question whether this is the world we want to live in.
In summary: This is the new normal, and we need to push back.
The landscape of financial interaction was markedly different fifty years ago. Customers enjoyed greater autonomy in opening accounts and managing their money, often choosing to engage with banks based solely on the cash they possessed. The era was characterized by less scrutinized transactions and, occasionally, the absence of ID requirements for account setup. The discretion once afforded to banks in determining necessary information for account creation has been supplanted by federal mandates, with customer information no longer confined to the private domain of the bank-customer relationship.
Financial institutions now file 30 million reports annually under the BSA, often erring on the side of over-reporting to avoid potential penalties. This practice underscores the pervasive nature of financial surveillance, with significant costs borne by both the industry and consumers.
The BSA marked a fundamental shift in the confidentiality dynamics between individuals and financial institutions, effectively involving the government in financial interactions instead of allowing people the dignity of privacy.
As surveillance mechanisms become increasingly embedded within the financial system, the safeguards of freedom are slowly chipped away, and the worst part is that nobody really recognizes that this is what is happening. Most people continue to hold on to the illusion of privacy, because what’s actually going on has been both hidden from view and normalized.
Changing this is an uphill battle, but it’s one that’s worth fighting. The first step is just making people aware of how far financial surveillance norms have shifted in just a few decades. The narrative of combating terrorism and serious crimes, while compelling, must be weighed against the potential for overreach and the erosion of fundamental liberties. It is through ongoing dialogue, rigorous oversight, and a commitment to upholding individual rights that society can navigate these challenges, especially in today’s increasingly interconnected world.
You should be able to use your own money without being tracked, profiled, and stored forever in a government database, and without banks being allowed to trade your financial data with each other. Let’s fight to bring back dignity to the financial landscape.
Yours in privacy,

Swedish researchers have developed a groundbreaking laser method that can rapidly identify chemical weapons and dangerous bacteria directly in the field – without needing to send samples to a laboratory. The technology is based on the principle that chemicals emit unique light signals when struck by laser.
Hazardous chemicals can be found everywhere – as pollutants in waterways, pesticides in food, or in the form of synthetic substances created to cause harm, such as narcotics and chemical warfare agents. Protecting people from these substances requires fast and reliable detection methods.
A new dissertation from Umeå University in northern Sweden demonstrates how laser technology can solve this problem.
Rasmus Öberg, doctoral student at the Department of Physics and the Industrial Doctoral School at Umeå University, has developed methods in collaboration with the Swedish Defence Research Agency (FOI) that can identify extremely small quantities of hazardous chemicals.
Unique "fingerprint" from each chemical
The principle is based on different molecules reacting differently when exposed to laser light.
— All hazardous chemicals consist of molecules with specific appearances and properties that make them dangerous. When these chemicals interact with light, for example from a laser, they emit a 'fingerprint' – a light signal that is unique to that particular chemical, says Öberg.
The methods can be used in conflict zones or for environmental monitoring to provide a rapid initial assessment of potential hazards. The results can then be followed up with more thorough laboratory analyses if needed.
— Traditional methods for detecting hazardous chemicals are often quite cumbersome and difficult to use outside the lab. With portable instruments and surfaces that amplify the light signals from the chemicals, we can take these methods into the real world. The collaboration with FOI, which has extensive experience working with hazardous substances, has been invaluable in this work, he continues.
Also works against bacteria
The dissertation also shows that similar laser technology can be used to trace dangerous bacteria and bacterial spores. This has great significance for the food industry and healthcare, where antibiotic-resistant bacteria pose a growing threat.
— Biological substances are often more complicated to detect, but by isolating characteristic chemicals from these bacteria and bacterial spores, we can detect even them in relatively small quantities. This is an exciting complement to established biological detection methods such as bacterial culture and PCR, notes the doctoral student.
The researchers now hope for continued development of the technology for use in more contexts where rapid and reliable analysis is crucial. In the long term, the methods could strengthen preparedness and security in areas such as environment, defense, and health.
Google has developed a quantum computing algorithm that, according to the company, opens up practical applications in areas including pharmaceutical research and artificial intelligence. The new algorithm is several thousand times faster than classical supercomputers.
Google announced on Wednesday that the company has successfully developed and verified the Quantum Echoes algorithm on its Willow quantum computing chip. The algorithm is 13,000 times faster than the most advanced classical computing algorithms running on supercomputers.
According to the company's researchers, Quantum Echoes could be used in the future to measure molecular structures, which could facilitate the development of new pharmaceuticals. The algorithm may also help identify new materials in materials science.
Another application is generating unique datasets for training AI models, particularly in areas such as life sciences where available datasets are limited.
— If I can't prove that data is correct, how can I do anything with it?, explained Google researcher Tom O'Brien about the importance of the algorithm being verifiable.
Congrats. Looks like quantum computing is becoming relevant.
Details about Quantum Echoes were published in the scientific journal Nature. Entrepreneur Elon Musk congratulated Google on X and noted that quantum computing is starting to become relevant.
Alphabet's Google is competing with other tech giants such as Amazon and Microsoft to develop quantum computers that can solve problems beyond the reach of today's computers.
The number of users of generative artificial intelligence in China has increased sharply during the first half of 2025. In June, 515 million Chinese people had access to AI services – an increase of 266 million in six months, according to official Chinese figures.
The data comes from a report presented on Saturday by the China Internet Network Information Center. It notes that domestically developed AI models have become popular among users.
A survey included in the report shows that over 90 percent of users say they prefer Chinese AI models.
Generative AI is being used in areas such as intelligent search, content creation, productivity tools and smart hardware. The technology is also being tested in agriculture, manufacturing and research.
The majority of users are young and middle-aged with higher education. Among users, 74.6 percent are under 40 years old, while 37.5 percent hold college, bachelor's or higher degrees.
The report claims that China has become increasingly important in the global AI field. As of April, the country had filed approximately 1.58 million AI-related patent applications, representing 38.58 percent of the global total – the most in the world.
