The worst technology failures of 2023

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. 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. Read the full story to find out the seven worst technologies of 2023.

How 2023 marked the death of anonymity online in China

There are so many people we meet on the internet daily whose real names we will never know. The TikTok teen who learned the trendy new dance, the anime artist who uploaded a new painting, the random commenter posting under the YouTube video you just watched. That’s the internet we are familiar with. 

In China, it’s already been impossible to be fully anonymous for a while now, thanks to a sophisticated system that requires identity verification to use any online services. Despite that, there were still corners of the Chinese internet where you could remain obscure. But lately, even this last bit of anonymity is slipping away. Read the full story.

Gene editing took center stage in 2023

Gene editing can be used to delete, insert, or alter portions of our genetic code. We’ve been able to modify DNA for years, but newer technologies like CRISPR mean that we can do it faster, more accurately, and more efficiently than ever before. 

In 2023, we saw the first approval of a CRISPR-based gene-editing therapy. And many more are to come. So let’s take a look at the developments that made news this year. What is the promise of gene editing, and what are the current pitfalls? Read the full story

In 2023, MIT Technology Review published a striking number of stories about gene editing. And really, that’s no surprise. Perhaps no technology has more power to transform medicine.

Is this the most energy efficient way to build homes?

When the Canadian engineer Harold Orr and his colleagues began designing an ultra-efficient home in Saskatchewan in the late ’70s, they knew that the trick wasn’t generating energy in a greener way, but using less of it. They needed to make a better thermos, not a cheaper coffee maker.

The result was the 1978 Saskatchewan Conservation House, a cedar-clad trapezoid that cut energy usage by 85%—and helped inspire today’s globally recognized passive-house standard for building design. It’s a marriage of efficiency and rigorously applied physics, and the associated benefits are vast. Read the full story

The big story

How Bitcoin mining devastated this New York town

GABRIELA BHASKAR

April 2022

If you had taken a gamble in 2017 and purchased Bitcoin, today you might be a millionaire many times over. But while the industry has provided windfalls for some, local communities have paid a high price, as people started scouring the world for cheap sources of energy to run large Bitcoin-mining farms.

It didn’t take long for a subsidiary of the popular Bitcoin mining firm Coinmint to lease a Family Dollar store in Plattsburgh, a city in New York state offering cheap power. Soon, the company was regularly drawing enough power for about 4,000 homes. And while other miners were quick to follow, the problems had already taken root. Read the full story.
