On the windy afternoon of March 17, 2017, I opened my mailbox and saw a white envelope from the San Francisco Unified School District. The envelope contained a letter assigning my younger daughter to a middle school. This letter was a big deal; San Francisco's public schools range from excellent to among the worst in the state, and kids are assigned to them through a lottery. The last time we put her name into the lottery, for kindergarten, she was assigned to one of the lowest-performing schools in California. Then we got a break: A private school offered a big discount on tuition.

SYDNEY – Australia will invest 7 billion Australian dollars ($5.2 billion) to develop and buy high-tech U.S. drones for joint military operations and to monitor waters including the South China Sea, it said Tuesday. Canberra has been embarking on its largest peacetime naval investment through a massive shipbuilding strategy that includes new submarines, offshore patrol vessels and frigates to shore up its defense capabilities. As part of this, the government will spend AU$1.4 billion to buy the first of six MQ-4C Triton maritime surveillance drones, with the aircraft to enter service from mid-2023, complementing seven P-8A Poseidon planes currently in use. "Together these aircraft will significantly enhance our anti-submarine warfare and maritime strike capability, as well as our search and rescue capability," Prime Minister Malcolm Turnbull said in a statement. "This investment will protect our borders and make our region more secure."

Flocks of robotic birds are taking to the skies of China equipped with high-tech surveillance technology, according to a report. The so-called "spy bird" programme, first reported by the South China Morning Post, is already in operation in at least five provinces and provides another tendril in the country's already advanced surveillance network. The dove-like drones are being developed by researchers at Northwestern Polytechnical University in the Shaanxi province, who have previously worked on stealth fighter jets used by China's airforce. One of the researchers involved said the roll out of the technology was still in its early stages. "The scale is still small," said Yang Wenqing, an associate professor at the university's School of Aeronautics who worked on the programme.

In a 2016 address to propaganda cadres and state-run media personnel, Chinese President Xi Jinping expressed dreams of instilling a new international media order "wherever the readers are, wherever the viewers are; that is where propaganda reports must extend their tentacles." As Xinhua News, China's largest state-run news agency, equips itself with "Media Brain," an artificial intelligence (AI) newsroom to assist all stages of reporting, these "tentacles" of propaganda may extend faster. Bringing AI to newsrooms can improve accuracy, enhance data analysis, and increase efficiency. According to a video released by Xinhua in January, the AI newsroom will do everything "from finding leads to news gathering, editing, distribution, and, finally, feedback analysis." Last week, Xinhua announced an update to Media Brain called "MAGIC," which will use machine generated content (MGC) for "fast-speed news production" and can automatically generate a news video in as fast as 10 seconds.

China is currently testing unmanned, miniaturized assault boats that could be used by the People's Liberation Army (PLA) to attack enemies at sea. Artificial intelligence technology that has traditionally been implemented in aerial drones will be used in the boats. "Once equipped with weapons, unmanned small combat vessels can attack the enemy in large numbers, similar to drones," said Li Jie, a Beijing-based naval expert. The prototypes, which resemble shark fins, were developed in a collaboration between a Guangdong-based tech company and the PLA. China isn't alone in developing unmanned vehicles, as the United States and other Western counties are working on creating "ant swarms" for operations on the ground, "drone swarms" for aerial operations and "shark swarms" for the sea.

I remember when Yves Béhar first showed me the August smart lock. It was years ago, before the product--which replaces the conventional combination of a metal key and mechanical tumbler with an authenticated mobile device and WiFi-connected electronic unit--was announced to the world. The designer dropped by my office at the Time & Life Building in Midtown Manhattan to give me a sneak peek. He demonstrated its utility by using his smartphone to digitally grant me access to his California beach house, right then and there. With a tap of his finger, he revoked it. Today I live a short walk from the Pacific Ocean and could actually take him up on the offer.

BEIJING – China's navy carried out drills in the South China Sea to simulate fending off an aerial attack, state media said on Friday, as China and the United States trade barbs over who is responsible for heightened tensions in the disputed waterways. U.S. Secretary of State Mike Pompeo expressed concern during a visit to Beijing on Thursday over China's efforts to militarize the seas. His remarks came after a flurry of U.S. activity in the region, including reports last week that U.S. Air Force B-52 bombers had flown near disputed islands that drew a sharp rebuke from China. China's navy carried out a simulated missile attack in an unspecified area of the South China Sea using three target drones making flyovers of a ship formation at varying heights, the official army newspaper said. The drills were part of efforts by an also unspecified training base to prepare for real-life combat against aerial targets after China's leadership said some training failed to prepare troops effectively, the paper said.

The New York City subway is a miracle, especially at 3 a.m. on a Friday night. But the system is also falling apart, and it's going to cost billions to keep the old trains running: $19 billion, at least according to one estimate from city planners. The time has come to give up on the 19th-century idea of public transportation, and leap for the autonomous future. Right now, fully autonomous cars are rolling around Pittsburgh, the San Francisco Bay area, and parts of Michigan, shuttling people from here to there with minimal manual intervention. Instead of fixing the old trains, let's rip out the tracks and fill the tunnels with fleets of autonomous vehicles running on pavement.

Today's leading minds talk AI with host Byron Reese In this episode, Byron and David discuss AI, jobs, and human productivity. Today's leading minds talk AI with host Byron Reese Byron Reese: This is Voices in AI brought to you by GigaOm, I'm Byron Reese. Today our guest is David Barrett. He is both the founder and the CEO of Expensify. He started programming when he was 6 and has been at it as his primary activity ever since, except for a brief hiatus for world travel, some technical writing, a little project management, and then founding and running Expensify. Welcome to the show, David. David Barrett: It's great of you to have me, thank you. Let's talk about artificial intelligence, what do you think it is? How would you define it? I guess I would say that AI is best defined as a feature, not as a technology. It's the experience that the user has and sort of the experience of viewing of something as being intelligent, and how it's actually implemented behind the scenes. I think people spend way too much time and energy on [it], and forget sort of about the experience that the person actually has with it. So you're saying, if you interact with something and it seems intelligent, then that's artificial intelligence? That's sort of the whole basis of the Turing test, I think, is not based upon what is behind the curtain but rather what's experienced in front of the curtain. Okay, let me ask a different question then– and I'm not going to drag you through a bunch of semantics. But what is intelligence, then? I'll start out by saying it's a term that does not have a consensus definition, so it's kind of like you can't be wrong, no matter what you say. Yeah, I think the best one I've heard is something that sort of surprises you.
