Welcome to our annual list of the worst technologies. This year, one technology disaster in particular holds lessons for the rest of us: the Titan submersible that imploded in the shadow of the Titanic

Everyone had warned Stockton Rush, the sub’s creator, that it wasn’t safe. But he believed innovation meant tossing out the rule book and taking chances. He set aside good engineering in favor of wishful thinking. He and four others died. 

To us it shows how the spirit of innovation can pull ahead of reality, sometimes with unpleasant consequences. It was a phenomenon we saw time and again this year, like when GM’s Cruise division put robotaxis into circulation before they were ready. Was the company in such a hurry because it’s been losing $2 billion a year? Others find convoluted ways to keep hopes alive, like a company that is showing off its industrial equipment but is quietly still using bespoke methods to craft its lab-grown meat. The worst cringe, though, is when true believers can’t see the looming disaster, but we do. That’s the case for the new “Ai Pin,” developed at a cost of tens of millions, that’s meant to replace smartphones. It looks like a titanic failure to us. 

Titan submersible

This summer we were glued to our news feeds as drama unfolded 3,500 meters below the ocean’s surface. An experimental submarine with five people aboard was lost after descending to see the wreck of the Titanic.

The Titan was a radical design for a deep-sea submersible: a minivan-size carbon fiber tube, operated with a joystick, that aerospace engineer Stockton Rush believed would open the depths to a new kind of tourism. His company, OceanGate, had been warned the vessel hadn’t been proved to withstand 400 atmospheres of pressure. His answer? “I think it was General MacArthur who said ‘You’re remembered for the rules you break,” Rush told a YouTuber.

But breaking the rules of physics doesn’t work. On June 22, four days after contact was lost with the Titan, a deep-sea robot spotted the sub’s remains. It was most likely destroyed in a catastrophic implosion.

In addition to Rush, the following passengers perished:

  • Hamish Harding, 58, tourist
  • Shahzada Dawood, 48, tourist
  • Suleman Dawood, 19, tourist
  • Paul-Henri Nargeolet, 77, Titanic expert

Lab-grown meat

Instead of killing animals for food, why not manufacture beef or chicken in a laboratory vat? That’s the humane idea behind “lab-grown meat.”

The problem, though, is making the stuff at a large scale. Take Upside Foods. The startup, based in Berkeley, California, had raised more than half a billion dollars and was showing off rows of big, gleaming steel bioreactors.

But journalists soon learned that Upside was a bird in borrowed feathers. Its big tanks weren’t working; it was growing chicken skin cells in much smaller plastic laboratory flasks. Thin layers of cells were then being manually scooped up and pressed into chicken pieces. In other words, Upside was using lots of labor, plastic, and energy to make hardly any meat.

Samir Qurashi, a former employee, told the Wall Street Journal he knows why Upside puffed up the potential of lab-grown food. “It’s the ‘fake it till you make it’ principle,” he said.

And even though lab-grown chicken has FDA approval, there’s doubt whether lab meat will ever compete with the real thing. Chicken goes for $4.99 a pound at the supermarket. Upside still isn’t saying how much the lab version costs to make, but a few bites of it sell for $45 at a Michelin-starred restaurant in San Francisco.

Upside has admitted the challenges. “We signed up for this work not because it’s easy, but because the world urgently needs it,” the company says.

Cruise robotaxi

Sorry, autopilot fans, but we can’t ignore the setbacks this year. Tesla just did a massive software recall after cars set on self-driving mode slammed into emergency vehicles. But the biggest reversal was at Cruise, the division of GM that became the first company to offer driverless taxi rides in San Francisco, day or night, with a fleet exceeding 400 cars.

Cruise argues that robotaxis don’t get tired, don’t get drunk, and don’t get distracted. It even ran a full-page newspaper ad declaring that “humans are terrible drivers.”

But Cruise forgot that to err is human—not what we want from robots. Soon, it was Cruise’s sensor-laden Chevy Bolts that started racking up noticeable mishaps, including dragging a pedestrian for 20 feet. This October, the California Department of Motor Vehicles suspended GM’s robotaxis, citing an “unreasonable risk to public safety.”

It’s a blow for Cruise, which had already been losing $2 billion a year. The company has since laid off 25% of its staff and fired its CEO and cofounder, Kyle Vogt, a onetime MIT student. “We have temporarily paused driverless service,” Cruise’s website now reads. It says it’s reviewing safety and taking steps to “regain public trust.” I’ve got a suggestion: stop trash-talking us humans and keep your eyes on the road.

Plastic proliferation

Plastic is great. It’s strong, it’s light, and it can be pressed into just about any shape: lawn chairs, bobbleheads, bags, tires, or thread.

The problem is there’s too much of it, as Doug Main reported in MIT Technology Review this year. Humans make 430 million tons of plastic a year (significantly more than the weight of all people combined), but only 9% gets recycled. The rest ends up in landfills and, increasingly, in the environment. Not only does the average whale have kilograms of the stuff in its belly, but tiny bits of “microplastic” have been found in soft drinks, plankton, and human bloodstreams, and even floating in the air. The health effects of spreading microplastic pollution have barely been studied.

Awareness of the planetary scourge is growing, and some are calling for a “plastics treaty” to help stop the pollution. It’s going to be a hard sell. That’s because plastic is so cheap and useful. Yet researchers say the best way to cut plastic waste is not to make it in the first place.

Humane Ai Pin

The New York Times declared it Silicon Valley’s “Big, Bold Sci-Fi Bet” for what comes after the smartphone. The product? A plastic badge called the Ai Pin, with a camera, chips, and sensors.

A device to wean us off our phone addiction is a worthy goal, but this blocky $699 pin (which also requires a $24-a-month subscription) isn’t it. An early review called the device, developed by startup Humane Ai, “equal parts magic and awkward.” Emphasis on the awkward. Users must use voice commands to send messages or chat with an AI (a laser projector in the pin will also display information on your hand). It weighs as much as a golf ball, so you probably won’t be attaching it to a T-shirt. 

It is the creation of a husband-and-wife team of former Apple executives, Bethany Bongiorno and Imran Chaudhri, who were led to their product idea with the guidance of a Buddhist monk named Brother Spirit, spending $225 million and filing 55 patents along the way.

 Clearly, there’s a lot of thought, money, and engineering involved in its creation. But as The Verge’s wearables reviewer Victoria Song points out, “it flouts the chief rule of good wearable design: you have to want to wear the damn thing.” As it is, the Ai Pin is neat, but it’s still no competition for the lure of a screen.

Social media superconductor

A room-temperature superconductor is a material offering no electrical resistance. If it existed, it would make possible new types of batteries and powerful quantum computers, and bring nuclear fusion closer to reality. It’s a true Holy Grail.

So when a report emerged this July from Korea that a substance called LK-99 was the real thing, attention seekers on the internet were ready to share. The news popped up first in Asia, along with an online video of a bit of material floating above a magnet. Then came the booster fuel of social media hot takes.

“Today might have seen the biggest physics discovery of my lifetime,” said a post to X that was viewed 30 million times. “I don’t think people fully grasp the implications … Here’s how it could totally change our lives.”

No matter that the post had been written by a marketer at a coffee company. It was exciting—and hilarious—to see well-funded startups drop their work on rockets and biotech to try to make the magic substance. Kenneth Chang, a reporter at the New York Times, dubbed LK-99 “the Superconductor of the Summer.”

But summer’s dreams soon ripped at the seams after real physicists couldn’t replicate the work. No, LK-99 is not a superconductor. Instead, impurities in the recipe could have misled the Korean researchers—and, thanks to social media, the rest of us too.

Rogue geoengineering

Solar geoengineering is the idea to cool the planet by releasing reflective materials into the atmosphere. It’s a fraught concept, because it won’t stop the greenhouse effect—only mask it. And who gets to decide to block the sun?

Mexico banned geoengineering trials early this year after a startup called Make Sunsets decided it could commercialize the effort. Cofounder Luke Iseman decided to launch balloons in Mexico designed to disperse reflective sulfur dioxide into the sky. The startup is still selling “cooling credits” for $10 each on its website.

Injecting particles into the sky is theoretically cheap and easy, and climate change is a huge threat. But moving too fast can create a backlash that stalls progress, as my colleague James Temple wrote. “They’re violating the rights of communities to dictate their own future,” one critic said. Even experimentalists know they’re seen as evil. That may have led one scientist who put up a balloon in the UK to name the test SATAN (for “Stratospheric Aerosol Transport and Nucleation”).

Iseman remains unrepentant. “I don’t poll billions before taking a flight,” he has said. “I’m not going to ask for permission from every person in the world before I try to do a bit to cool Earth.”
