The Download: The Merge arrives, and China’s AI image censorship

Must Read

What’s happened: “The Merge”, a major upgrade to the Ethereum cryptocurrency platform, was finally completed early this morning after a six-year buildup. Ethereum now uses proof of stake, a way to approve new transactions that promises to cut the blockchain’s energy requirements by 99.9% and usher in a new era for the second-largest cryptocurrency. 

Why it matters: It would be hard to overstate how much industry excitement there has been around this shift. Many hope it can both rehabilitate the reputation of crypto for skeptics and improve the efficiency of Ethereum’s enormous ecosystem of businesses and developers, cutting fees and helping it to scale.

What’s next?: We won’t know right away whether the Merge lives up to its transformative promise. Power dynamics are still a concern, and some of the scaling efficiencies that supporters are most excited about may not arrive until well into 2023. But there’s no doubting the fact that one of crypto’s biggest players investing in a less destructive, more efficient ecosystem is, in itself, a huge achievement. Read the full story.

There’s no Tiananmen Square in the new Chinese image-making AI

With ERNIE-ViLG, a new AI developed by the Chinese tech company Baidu, you can generate images that capture the cultural specificity of China.

But there are many things—like Tiananmen Square, the country’s second-largest city square and a symbolic political center—that the AI refuses to show you. 

It’s not rare for similar AIs to limit users from generating certain types of content. Open AI’s DALL-E 2 prohibits sexual content, faces of public figures, or medical treatment images. But the case of ERNIE-ViLG underlines the question of where exactly the line between moderation and political censorship lies. Read the full story.

The big story

The Soviets turned the Volga River into a machine. Then the machine broke.

December 2021

About 2,300 miles long, the Volga—sometimes referred to as “Mother Volga”—is the longest river in Europe and the biggest by water flow. The history of the Big Volga project is, in a sense, the history of Soviet industrialization. It is also a history of rivalry with the US, which for decades raced the Soviets to build bigger, more impressive dams.

But the project tried to do too much. The river has become polluted, silted up, and overwhelmed by invasive species. Water flows at a tenth of the speed it did before the dams were constructed, and widespread toxic algal blooms are now common. 

And now that the Volga basin has been identified as one of the regions most at risk of climate change-induced drought, it’s not an exaggeration to say that Russia’s mother river is broken. Read the full story.
