What does GPT-3 “know” about me?

One of the biggest stories in tech this year has been the rise of large language models (LLMs). These are AI models that produce text a human might have written—sometimes so convincingly they have tricked people into thinking they are sentient.

These models’ power comes from troves of publicly available human-created text that has been hoovered from the internet. If you’ve posted anything even remotely personal in English on the internet, chances are your data might be part of some of the world’s most popular LLMs. 

My colleague Melissa Heikkilä, our AI reporter, recently started to wonder what data these models might have on her—and how it could be misused. A bruising experience a decade ago left her paranoid about sharing personal details online, so she put OpenAI’s GPT-3 to the test to see what it “knows” about her. Read about what she found.

How ammonia could help clean up global shipping

The news: Foul-smelling ammonia might seem like an unlikely fuel to help cut greenhouse-gas emissions. But it could also play a key role in decarbonizing global shipping, providing an efficient way to store the energy needed to power large ships on long journeys.

What’s happening: The American Bureau of Shipping recently granted early-stage approval for some ammonia-powered ships and fueling infrastructure, meaning such ships could hit the seas within the next few years. While the fuel would require new engines and fueling systems, swapping it in for fossil fuels that ships burn today could help make a significant dent in global carbon emissions.

What’s next: Some companies are looking even further into the future, with New York–based Amogy raising nearly $50 million earlier this year to use the chemical for fuel cells that promise even greater emissions cuts. If early tests for ammonia work out, these new technologies could help the shipping industry to significantly reduce its emissions. Read the full story.

The big story

Humanity is stuck in short-term thinking. Here’s how we escape.

October 2020

Humans have evolved over millennia to grasp an ever-expanding sense of time. We have minds capable of imagining a future far off into the distance. Yet while we may have this ability, it is rarely deployed in daily life. If our descendants were to diagnose the ills of 21st-century civilization, they would observe a dangerous short-termism: a collective failure to escape the present moment and look further ahead.

The world is saturated in information, and standards of living have never been higher, but so often it’s a struggle to see beyond the next news cycle, political term, or business quarter. How to explain this contradiction? Why have we come to be so stuck in the “now”? Read the full story.
