Today on the AI Breakdown, a former Google engineer has been arrested for stealing and sharing trade secrets around AI with a Chinese company. Before that, on the Brief, Microsoft deals with a whistleblower who says that Copilot Designer is not safe for the public.

Welcome back to the AI Breakdown Brief. All the AI headline news you need in around five minutes. As AI gets more advanced, the range of divergent opinions about AI and its role in business, commerce and society gets wider and wider. And that happens not just in society, but also in the context of specific companies. A couple times over the last few years we've seen people leave a big AI lab that they were working with because they started to disagree with that company's approach to how they were handling AI related issues. The latest story like that is an engineer who has left Microsoft and who claims that its AI Image Generator creates harmful imagery too easily. Shane Jones was an AI engineer at Microsoft who had worked there for about six years, and at the end of last year in November and December, he was part of a red teaming effort on Copilot Designer. Copilot Designer is an AI image generator. Red teaming is a process by which people try to actively root out vulnerabilities and ways to get around guardrails to better understand how an AI is going to behave in the wild. Jones claimed that the images that came up were not something that should be available to the public. CNBC writes the AI service depicted demons and monsters alongside terminology related to abortion rights, teenagers with assault rifles, sexualized images of women in violent tableaus, and underage drinking and drug use. All of those scenes generated in the past three weeks have been recreated by CNBC this week using the Copilot tool, which was originally called Bing Image Creator, said Jones. It was an eye opening moment. It's when I first realized, wow, this is really not a safe model, writes cnbc. Jones was so alarmed by his experience that he started internally reporting his findings in December. While the company acknowledged his concerns, it was unwilling to take the product off the market. Jones said Microsoft referred him to OpenAI, and when he didn't hear back from the company, he posted an open letter on LinkedIn asking the startup's board to take down Dall E3 for an investigation. Microsoft's legal department then said to remove that post immediately. But then in January, he wrote a letter to US Senators on the matter and later also met with Senate staffers from the Committee on Commerce, Science and Transportation. Then this week he went even farther, sending a letter to FTC Commission Chair Lina Khan and another to Microsoft's Board of directors, also sharing those letters with cnbc. Basically, Jones said that he wanted first for Copilot Designer to be removed until they could put in better safeguards, but then, barring that, he wanted to add disclosures to the product and change the rating on Google's Android app to make it just for mature audiences. Microsoft, for their part, said, we are committed to addressing any and all concerns employees have in accordance with our company policies and appreciate employee efforts in studying and testing our latest technology to further enhance its safety. When it comes to safety bypasses or concerns that could have potential impact on our services or partners, we have established robust internal reporting channels to properly investigate and remediate any issues which we encourage employees to utilize so we can appropriately validate and test their concerns. Which is of course a very brush off sort of answer. And the question will be whether the story actually picks up any more traction from here. Meanwhile, on the other side of the company has announced the quote, New Era of Work event designed for the company's business customers and will show off new Surface Pro 10 and Surface Laptop 6 devices. Of course, there will be a big focus on the AI improvements that are coming to Windows 11 over in another tech giant's world, Tom Allison, the head of Facebook within Meta, said that the company is investing heavily in the development of an AI system designed to power Facebook's entire video system. Allison said that the technology roadmap that goes into 2026 involves the development of an AI recommendation model that powers short videos like Instagram reels as well as longer videos. Allison held this discussion at a Morgan Stanley tech conference in San Francisco, noted that in the past, the various different video products within Facebook and Meta had all been powered by different systems. Now, part of why AI has been so captivating to the markets is that it's not just theoretical and is actually producing results now. For example, Alison discussed that implementing a new type of AI powered model architecture helped Facebook increase an 8 to 10% gain in reels watch time, which of course translates to more ad dollars, said Allison. Instead of just powering reels, we're working on a project to power our entire video ecosystem with this single model and then we can add our feed recommendation product to also be served by this model. If we get this right, not only will the recommendations be kind of more engaging and more relevant, but we think the responsiveness of them can improve as well. We wanted flying cars, we got a better video recommendation engine. Salesforce, another tech giant, continues its relentless push into AI, announcing a new AI tool for doctors. The tool is called Einstein Copilot Health Actions and is designed to try to help automate a slate of manual administrative tasks that can be a real drag on productivity and increase burnout. They say that the tool will allow doctors to book appointments, summarize patient information and send referrals, all by prompting AI in natural language. They say that the tool will also allow organizations to digitize health assessments without having to manually type or code them. Now in VC land, Voqal AI proponent Andreessen Horowitz is aiming to raise 6.9 billion for a new set of funds, including two that will be focused on artificial intelligence. A16Z is targeting a $6.9 billion for a master feeder fund that's expected to close in early April. Half of that is supposed to go to the firm's growth fund, which would represent a size decline from its $5 billion predecessor, but then spending 15% on an AI infrastructure fund and 15% on an AI apps fund. In other words, friends, the AI funding rush is not likely to slow down anytime soon. However, that is going to do it for today's AI Breakdown brief. Next up, the main AI breakdown Today's podcast is brought to you by Plum.

One of the defining relationships on the global stage right now is the relationship between China and us. It is a great power struggle of a different flavor in a way that we haven't had for a couple decades now. Interestingly, if you pay any attention to artificial intelligence, you'll know that this has become a major vector of that competition. That's manifested, of course, in prohibitions around the type of technology that American companies can share with their Chinese counterparts and sell into the Chinese market. This has left companies like AMD and Nvidia constantly working to produce lower power chips that get in under US thresholds in order to keep that as a valuable market for themselves. But it also looms large as a question of policy when we are debating things like open source AI versus closed source AI. People's thoughts about competition with China tends to influence that conversation, although fascinatingly that can head in two very different directions. Some people see open source AI development as the lifeblood of American innovation and the way that we out compete China we, whereas other folks see it as just a way for China to get access to our most advanced models. However, there is also just the plain old question of espionage and that's where our story begins today. A former Google teamer, Lin Wei Ding, has been arrested in California and accused of stealing Google's AI secrets and sharing them with China, writes the New York Times. A Chinese citizen who recently quit his job as a software engineer for Google in California has been charged with trying to transfer artificial intelligence technology to a Beijing based company that paid him secretly, according to a federal indictment unsealed on Wednesday, the indictment reads. A federal grand jury indicted Lin Wei Ding, AKA Leon Ding, charging him with four counts of theft of trade secrets in connection with an alleged plan to steal from Google LLC proprietary information related to AI technology, according to the indictment returned on March 5 and unsealed earlier today. That's Wednesday, March 6. 38 year old Ding, a national of the People's Republic of China, transferred sensitive Google trade secrets and other confidential information from Google's network to his personal account while secretly affiliating himself with PRC based companies in the AI industry, said Attorney General Merrick Garland. The Justice Department will not tolerate the theft of artificial intelligence or other advanced technologies that could put our national security at risk. In this case, we allege the defendant stole artificial intelligence related trade secrets from Google while secretly working for two companies based in China. We will fiercely protect sensitive technologies developed in America from falling into the hands of those who should not have them. Deputy Attorney General Lisa Monaco added that the defendant had stolen over 500 confidential files and that, quote, the Justice Department will relentlessly pursue and hold accountable those who would siphon disruptive technologies, especially AI, for unlawful export. Also quoted in the announcement was FBI Director Christopher Wray, who said today's charges are the latest illustration of the lengths affiliates of companies based in the People's Republic of China are willing to go to steal American innovation. The theft of innovative technology and trade secrets from American companies can cost jobs and have devastating economic and national security consequences. The FBI will continue its efforts to vigorously pursue those responsible for stealing U.S. companies Intellectual property and most closely guarded secret secrets. The arrest was carried out under the auspices of something called the Disruptive Technology Strike Force, said Assistant Secretary Matthew Axelrod of the Commerce Department's Office for Export Enforcement. Quote, in the one year since its inception, the Disruptive Technology Strike Force has been relentless in protecting advanced US Technologies like artificial intelligence from malign actors. Let today's announcement serve as further warning. Those who would steal sensitive US Technology risk finding themselves on the wrong end of a criminal indictment. So let's pause here before we get into the specifics of what was actually stolen. There are two things that are notable to me about this announcement. The first is the aggressiveness of the posture. This is probably a reflection of the state of the relationship between the US And China, but it is really notable. This is not soft language at all. This is you've brought down the wrath of the one remaining superpower in the world kind of language. The other thing, though, that's notable is how much AI is viewed as a national security and defense priority. This is not just a question of American companies and their economic competitiveness. This is about the inviolability of the sanctity of the United States as a whole. It seems to me very clear that they are trying to make an example of Leon Ding. They want this to be as loud as humanly possible to show how aggressive they're going to be when it comes to AI. And that's fairly notable. It sends a signal about where AI ranks in terms of priorities, and it seems to be pretty high. Now, what was the information that was actually stolen? The Verge writes. Much of the stolen data allegedly revolves around Google's Tensor Processing Unit, or tpu chips. In the indictment, for example, we see that between June 1, 2022 and April 17, 2023, the defendant allegedly stole chip architecture and software design specifications For TPU version 6 hardware software, system management and performance specifications for GPU chips deployed in Google supercomputing data centers, and software design specifications for Google CMS that managed machine learning workloads on TPU and GPU chips in Google supercomputing data centers. Now, this was not some sophisticated hack, the Verge writes. The government accuses Ding of transferring those files to a personal Google cloud account between May 2022 and May 2023. He allegedly did so by copying data from the Google source files into the Apple Notes application on his Google issued MacBook laptop and then converting them from Apple notes to PDFs to avoid detection by Google's data loss prevention systems. So Google, one of the five biggest companies in the world or six, whatever you get the point was stymied by a guy copy pasting into Apple Notes and then turning Apple notes into PDFs. Now one of the other crazy parts of the story is that it seems like for a period of six months while he was technically at Google, still he was also joining and starting Chinese startups. The Verge again writes, the government says that less than a month after he began stealing files, a Chinese machine learning company named Rongxu offered to make him cto. He flew to China for five months to raise funds for the company and he subsequently founded and led a machine learning startup named Zhe Xuan, all while still working for Google. He resigned from Google in December 2023 and reportedly booked a one way ticket to Beijing, scheduled to depart two days past his end date after the company began asking him about his uploads. Apparently at one point he faked being present at Google in the US by having a different employee scan his badge. So we know a little bit about what he was stealing, but what was Ding actually doing at Google? The indictment reads. The focus of Ding's work was the software platform developed in Google's network of supercomputing data centers. Ding's job responsibilities included development of software that allowed GPU to function efficiently for machine learning and AI applications or other purposes required by Google or Google Cloud clients. Due to Ding's job responsibilities, he was authorized to access Google confidential information related to Google's supercomputing data centers, including the hardware infrastructure, the software platform, and the AI models and applications they supported. It also sounds like although they missed the activity for a while, Google eventually did catch wind of the idea that something was going on, the indictment again reads. On or about December 2, 2023, Ding uploaded additional files from the Google network to another personal Google Drive account while Ding was in the PRC. On December 8, 2023, after Google detected this activity, Ding told a Google investigator that he had uploaded the files to his personal account to use the information as evidence of the work that he had conducted at Google. Ding assured the investigator that he had no intention of leaving Google. Ding signed a self deletion affidavit dated December 8, basically saying that he had destroyed the information. This was of course not true. It finally came down, however, when on December 26 Ding resigned via email and on December 29 quote, Google learned that Ding had presented as the CEO of zhuan at the Miracle plus investor conference in Beij in November 24, 2023. Google then suspended Ding's network access and remotely locked his Google laptop. Google searched Ding's network activity history and discovered Ding's unauthorized uploads from May 22 through May 2023. That's also when they discovered another employee swiping Ding's badge. And on January 4, security personnel retrieved Google's Ding laptop and mobile device from his residence. On January 6, the FBI got involved. And then finally, he was arrested yesterday. On Wednesday morning in Newark, California, the New York Times points out that this is a big and ongoing issue. Even outside of this case, they write, accusations of intellectual property theft have been a major sticking point in US China relations for years. A Chinese national was arrested in 2015 for selling some of IBM's source code to parties in China. In 2018, a former Apple employee was apprehended as he tried to board a flight to Beijing with the company's autonomous driving trade secrets. The same year, the Chinese firm Sonova Wind Group was convicted of stealing wind turbine technology from a Massachusetts based company, AMSC, which incurred more than 800 million in losses. In October, Christopher Wray, the FBI director, said that intellectual property theft from China was a danger to U.S. economic and national security, describing it as the, quote, defining threat of this generation. It seems like this is an issue that is poised to just increase in significance. The South China Morning Post, for example, this morning reported that in meetings at the Chinese People's Political Consultative Conference, or cppcc, a delegate who leads a Chinese AI company said, quote, objectively speaking, despite the great efforts we have been making, our difference with the US is still huge in a certain sense. As new developments in AI emerge exponentially, if no decisive and groundbreaking measures are taken, we are at risk of seeing an even wider gap. Problems in the development of information technology cannot be solved by creating applicable scenarios, nor through breakthroughs in specific technologies. It is not even a problem about talent and basic research. It is about many things from all aspects. We are all very anxious. The SCMP goes on. While China's AI industry was generally seen as more competitive in the very tech rivalry between the two countries, the latest launch of OpenAI, Sora and ChatGPT has raised questions about China's progress in catching up with the US to cope, Chinese tech companies, which have insisted that chip restrictions would not affect their development in the short term, have relied on their existing inventories or have turned to domestic AI chip makers. But after SORA was launched last month, the State Council's State Owned Asset Supervision and Administration Commission urged firms under direct control by the central government to, quote, embrace the profound changes brought about by AI. In other words, SORA has China even more convinced that they're behind and needing to take drastic steps to keep up. Fascinating stuff going on out there in the world. AI is very clearly at the center of the geopolitical conversation. That, however, is going to do it for today's AI breakdown. Till next time, peace.
