Computing’s Top Prize Goes to Ethernet Creator Bob Metcalfe

The network technology first linked the computers of schools and offices. Now it connects us all to the internet.

Bob Metcalfe has won the 2022 Turing Award, the computing industry’s top prize, for creating the Ethernet standard that today connects billions of devices to wired and wireless networks.

The idea behind Ethernet emerged in a May 22, 1973, memo Metcalfe wrote to his bosses at Xerox PARC, the Palo Alto Research Center famous for a series of seminal computing inventions. Fifty years later, Ethernet connects virtually every laptop and smartphone to the internet.

The Turning Award, named after pioneer and famed World War II code-breaker Alan Turing, is bestowed by the Association for Computing Machinery and comes with a $1 million prize. It’s often referred to as the Nobel Prize of computing. Previous Turing Award winners include dozens of luminaries who invented chip designs, encryption, programming tools, the web, the internet, and the AI technology that’s become so hot today.

Metcalfe also founded 3Com, a company that profited greatly from the commercialization of Ethernet, and worked as a columnist, professor and venture capitalist, among other careers.

«It’s my sixth career,» Metcalfe said in an interview. He’s writing software to try to use computers to simulate geothermal energy plants and other complex real-world systems. «My attitude is I want to do simulation not to optimize things, but to discover them.»

Metcalfe’s law

Metcalfe also is famous for Metcalfe’s Law — an idea he had, though not a title he came up with. The law states that the value of a network increases proportionally to the square of the number of devices that can use it.

«It was a good way to make a sales pitch at 3Com,» Metcalfe said of the idea. Later, though, he validated the idea by connecting Facebook’s membership total with its revenue. «For the first 10 years of Facebook, there’s a perfect fit.»

Ethernet speed boosts

Wired Ethernet began at Xerox PARC with data transfer speeds of 2.94 megabits per second. Now it’s reached 800 gigabits per second — about 272,000 times faster. Another doubling is in the works, to 1.6 terabits per second.

Wired Ethernet ports have faded from laptops and never arrived on phones. But the technology was adapted to the Wi-Fi standards, bringing new convenience and ubiquity to the internet. (Metcalfe prefers Wi-Fi’s original name, Wireless Ethernet.)

Token Ring grudge

Today, it’s nearly universal in digital devices, but Ethernet had stronger competition in its early days. The top of the list of rivals was IBM’s Token Ring.

«Token Ring was a 20-year pain in the neck. Finally, we killed it,» Metcalfe said.

He’s still sore about it, he said in a half-joking tone.

«I’m only human. I bear a grudge against those bastards,» Metcalfe said. «It’s been 50 years. You’d think by now I would have forgiven them all, but the Token Ring people are not invited to my dinner parties.»

Honor’s Audacious Robot Phone Is Real and I Just Got a First Glimpse

Forget foldables, this might just be the most unconventional phone design I’ve seen in years.

When Honor first announced its quirky Robot Phone back in October, I said I would have to see it and hold it to believe it’s real. Three months later, I’m halfway there at least.

At CES 2026 I got a first glimpse of a prototype of the phone with its pop-out DJI Osmo-like camera and gimbal. Given that part of the body of the phone is given over to housing these elements when they’re folded away, it’s understandably not among the cohort of ultra-thin devices we’ve seen over the past year or so.

I wasn’t allowed to touch or manipulate the phone or its arm, but I watched as a member of Honor’s team moved the camera between different positions. It was interesting to see how neatly the arm packed away, leaving the black phone looking, at a glance, almost like any other generic device with a particularly expansive camera module. But I can’t deny that I’m still keen to get my hands on it to see how well the robotic element of the phone actually operates.

Fortunately, I don’t have long to wait. At Mobile World Congress, which takes place in Barcelona in March, Honor will allow me to touch and hold the phone. At that point, the robotic arm will be working, so it won’t have to be manually adjusted. We know frustratingly little else about the phone at this stage beyond its design, but its full specs will also be announced at MWC.

When it finally launches, the Robot Phone is likely to be something of a niche product that appeals mainly to content creators. But it will also inject a much-needed dose of design daring into an industry that has struggled to show much imagination over the past decade.

Tech journalists, myself included, are guilty of complaining about the homogenous designs of most smartphones, while urging companies to take more risks and give us something to really get excited about. The introduction of foldable phones has been a breath of fresh air, but the Robot Phone is a next-level example of thinking beyond the conventional boundaries of phone design.

I, for one, can’t wait to see — and hold — more.

Finally, I’ve Found a Worthy Successor to the Iconic ’90s Tamagotchi

This virtual pet grows physically bigger the more you play with it.

Back in 1996, when Tamagotchis became the must-have toy, I was 8 years old — the perfect target audience. I remember handing over my crisp British £10 note to the good people at Toys R Us, shaking with anticipation. It was the most money I’d ever spent in one go, but I knew it would be worth it to own one of the magenta virtual pets just like all of my classmates.

Thirty years later at CES 2026 in Las Vegas, I finally found a worthy successor to my treasured pixelated companion. Sweekar is a Tamagotchi-inspired pocket pet, an AI companion that grows physically bigger as it matures.

Sweekar begins life as an egg with ears. In a demo, it lays in my hand, and I tap it gently three times on the head, making its yellow ears glow. The egg opens to reveal a screen displaying a cracking shell. A pair of sleepy eyes pops into view.

On the Las Vegas show floor, Sweekar was ready to go for my demo, but usually, the incubation stage can take up to two days. The egg perches on its base until the shell cracks open, from which point little Sweekar will spend between five and seven days in baby stage. Next up is the teen stage (21 to 45 days), followed by Sweekar adulthood.

With each life stage, Sweekar grows a little bigger. Just like the original Tamagotchi, each stage brings a series of new challenges for you as its owner. The early days mean high-frequency care with basic language learning. The teen years bring greater intelligence and a more distinct personality. Eventually, you can progress to owning a pet that’s autonomous, requiring less care, but which has more fun gameplay options. And… Sweekar can also die if you neglect it.

In all of these senses, it feels remarkably true to the spirit of the original Tamagotchi, but with AI technology that could ultimately provide a more rewarding experience in the long term. Hopefully, it will inspire owners to keep it alive longer than the many little Tamagotchi chicks that perished due to lack of care.

If you want to get your hands on a Sweekar to bring some ’90s-inspired magic to a kid’s childhood (or if you’re just feeling nostalgic — I won’t judge), it will be available via Kickstarter later this year. You’ll need more than a £10 note to secure one, however. Sweekar will be priced at a far more substantial $150.
