In 2016, the Japanese government announced a plan for the emergence of a new kind of society. Human civilization, the proposal explained, had begun with hunter-gatherers, passed through the agrarian and industrial stages, and was fast approaching the end of the information age. As then Prime Minister Shinzo Abe put it, “We are now witnessing the opening of the fifth chapter.” This chapter, called Society 5.0, would see made-on-demand goods and robot caretakers, taxis, and tractors. Many of the innovations that will enable it, like artificial intelligence, might be obvious. But there is one k ..read more

It’s late in the afternoon of 2 April 2023 on the island of Kauai. The sun is sinking over this beautiful and peaceful place, when, suddenly, at 4:25 pm, there’s a glitch: The largest generator on the island, a 26-megawatt oil-fired turbine, goes offline. This is a more urgent problem than it might sound. The westernmost Hawaiian island of significant size, Kauai is home to around 70,000 residents and 30,000 tourists at any given time. Renewable energy accounts for 70 percent of the energy produced in a typical year—a proportion that’s among the highest in the world and that can be hard to s ..read more

The idea of powering civilization from gigantic solar plants in orbit is older than any space program, but despite seven decades of rocket science, the concept—to gather near-constant sunlight tens of thousands of kilometers above the equator, beam it to Earth as microwaves, and convert it to electricity—still remains tantalizingly over the horizon. Several recently published deep-dive analyses commissioned by NASA and the European Space Agency have thrown cold water on the hope that space solar power could affordably generate many gigawatts of clean energy in the near future. And yet the dr ..read more

No matter where professionals are in their tech career—whether just starting out or well established—it’s never a bad time for them to reassess their skills to ensure they are aligned with market needs. As the professional home for engineers and technical professionals, IEEE offers a wealth of career-development resources. To showcase them, from 14 to 20 April the organization is holding its annual Education Week. The event highlights the array of educational opportunities, webinars, online courses, activities, and scholarships provided by IEEE’s organizational units, societies, and councils ..read more

Although the race to power the massive ambitions of AI companies might seem like it’s all about Nvidia, there is a real competition going in AI accelerator chips. The latest example: At Intel’s Vision 2024 event this week in Phoenix, Ariz., the company gave the first architectural details of its third-generation AI accelerator, Gaudi 3. With the predecessor chip, the company had touted how close to parity its performance was to Nvidia’s top chip of the time, H100, and claimed a superior ratio of price versus performance. With Gaudi 3, it’s pointing to large-language-model (LLM) performance w ..read more

I’ve enjoyed reading magazine articles about Ethernet’s 50th anniversary, including one in the The Institute. Invented by computer scientists Robert Metcalfe and David Boggs, Ethernet has been extraordinarily impactful. Metcalfe, an IEEE Fellow, received the 1996 IEEE Medal of Honor as well as the 2022 Turing Award from the Association for Computing Machinery for his work. But there is more to the story that is not widely known. During the 1980s and early 1990s, I led Digital Equipment Corp.’s networking advanced development group in Massachusetts. I was a firsthand witness in what was a per ..read more

You can’t see, hear, taste, feel, or smell it, but software is everywhere around us. It underpins modern civilization even while consuming more energy, wealth, and time than it needs to and burping out a significant amount of carbon dioxide into the atmosphere. The software industry and the code it ships need to be much more efficient in order to minimize the emissions attributable to programs running in data centers and over transmission networks. Two approaches to software development featured in Spectrum‘s April 2024 issue can help us get there. In “Why Bloat Is Still Software’s Biggest V ..read more

The stretchable battery is gaining momentum in the electronics industry, where it might one day serve as an energy storage medium in fitness trackers, wearable electronics, and even smart clothing. Researchers believe the concept will become more valuable in the next decade, as electronic devices migrate closer and closer to human skin. “For many applications, such as wearables, stretchability is necessary since our skin stretches as we move,” said James Pikul, a professor of mechanical engineering at the University of Wisconsin–Madison. “A battery that only flexes would feel uncomfortable t ..read more
