Leading global firms Intel, Toyota and Airbus have all expanded their presence within the developing flying taxi market following recent announcements from Joby Aviation and Airbus’s Vahana unit.

Santa Cruz-based Joby Aviation revealed that it received $100mn in a Series B financing round led by Intel Capital, with Toyota AI Ventures also investing into the startup.

Joby Aviation will use the funding to aid the development of its innovative all-electric vertical takeoff and landing (eVTOL) passenger aircraft that is designed to offer regional and local air transportation.

The company claims that the Joby Aviation 5 seat vehicle will both be faster than existing products from its competitors, including the Airbus Vahana, whilst also offering a 150 mile range from a single charge.

“We have spent the last ten years developing the technologies that have made our full-scale technical demonstrator possible and are now ready to build a commercial version of the aircraft,” said Joby Aviation founder and CEO JoeBen Bevirt. “We’re excited to have attracted the backing of leaders in auto manufacturing, data intelligence, and transportation sectors.”

Meanwhile, Airbus revealed that its Vahana electric autonomous aircraft successfully completed its first full-scale flight test, lasting 53 seconds and reaching a height of 16 feet.

“In just under two years, Vahana took a concept sketch on a napkin and built a full-scale, self-piloted aircraft that has successfully completed its first flight,” said Zach Lovering, Project Executive of Vahana.

The companies join the likes of Uber with its Elevate unit and Boeing, having recently unveiled its own unmanned air vehicle prototype, in making inroads into the emerging industry, with competition expected to increase, similarly to how it has done in the autonomous vehicle market.

Google AI Designs Next-Gen Chips In Under 6 Hours

Google AI’s deep reinforcement learning algorithms can optimise chip floor plans exponentially faster than their human counterparts

In a Google-Nature paper published on Wednesday, the company announced that AI will be able to design chips in less than six hours. Humans currently take months to design and layout the intricate chip wiring. Although the tech giant has been working in silence on the technology for years, this is the first time that AI-optimised chips have hit the mainstream—and that the company will sell the result as a commercial product. 


“Our method has been used in production to design the next generation of Google TPU (tensor processing unit chips)”, the paper’s authors, Azalea Mirhoseini and Anna Goldie wrote. The TPU v4 chips are the fastest Google system ever launched. “If you’re trying to train a large AI/ML system, and you’re using Google’s TensorFlow, this will be a big deal”, said Jack Gold, President and Principal Analyst at J.Gold Associates


Training the Algorithm 

In a process called reinforcement learning, Google engineers used a set of 10,000 chip floor plans to train the AI. Each example chip was assigned a score of sorts based on its efficiency and power usage, which the algorithm then used to distinguish between “good” and “bad” layouts. The more layouts it examines, the better it can generate versions of its own. 


Designing floor plans, or the optimal layouts for a chip’s sub-systems, takes intense human effort. Yet floorplanning is similar to an elaborate game. It has rules, patterns, and logic. In fact, just like chess or Go, it’s the ideal task for machine learning. Machines, after all, don’t follow the same constraints or in-built conditions that humans do; they follow logic, not preconception of what a chip should look like. And this has allowed AI to optimise the latest chips in a way we never could. 


As a result, AI-generated layouts look quite different to what a human would design. Instead of being neat and ordered, they look slightly more haphazard. Blurred photos of the carefully guarded chip designs show a slightly more chaotic wiring layout—but no one is questioning its efficiency. In fact, Google is starting to evaluate how it could use AI in architecture exploration and other cognitively intense tasks. 


Major Implications for the Semiconductor Sector 

Part of what’s impressive about Google’s breakthrough is that it could throw Moore’s Law, the axion that the number of transistors on a chip doubles every five years, out the window. The physical difficulty of squeezing more CPUs, GPUs, and memory on tiny silicon die will still exist, but AI optimisation may help speed up chip performance.


Any chance that AI can help speed up current chip production is welcome news. Though the U.S. Senate recently passed a US$52bn bill to supercharge domestic semiconductor supply chains, its largest tech firms remain far behind. According to Holger Mueller, principal analyst at Constellation Research, “the faster and cheaper AI will win in business and government, including with the military”. 


All in all, AI chip optimisation could allow Google to pull ahead of its competitors such as AWS and Microsoft. And if we can speed up workflows, design better chips, and use humans to solve more complex, fluid, wicked problems, that’s a win—for the tech world and for society.
