Plus: Elon Musk has met with US politicians to discuss Twitter fairness

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

A watermark for chatbots can spot text written by an AI

What’s happened: A new method could help us to spot AI-generated texts. Watermarking buries hidden patterns in the text that are invisible to the human eye, but lets computers detect that the text probably comes from an AI system or a human.

Why it matters: ChatGPT is one of a new breed of large language models that generate fluent text that reads like a human could have written it. These AI models regurgitate facts confidently, but are notorious for spewing falsehoods, which makes it worrying that they’re already being adopted for everything from essays to workout plans. To the untrained eye, it is almost impossible to detect whether a passage is written by an AI model or human. 

And it works? In studies, these watermarks have already shown that they can identify AI-generated text with near certainty. If they’re embedded in large language models, they could help prevent some of the problems that these models have already caused. Read the full story.

How do I know if egg freezing is for me?

The decision to freeze your eggs is incredibly personal, and not always easy. While egg freezing is often sold as a fertility insurance policy, we’re still not entirely sure how successful the procedure is likely to be for any individual person, or how success rates vary by age.

We do know that it is expensive—we’re talking potentially tens of thousands of dollars for hormonal treatments, egg collection procedures, and years of cryopreservation. And we know that it’s not without risks. 

That’s why the team behind a new decision-making tool hope it will help to clear up some of the misconceptions around the procedure—and give would-be parents a much-needed insight into its real costs, benefits, and potential pitfalls. Read the full story.

The big story

How Worldcoin recruited its first half a million test users

April 2022

In December 2021, residents of the village of Gunungguruh, Indonesia, were curious when technology company Worldcoin turned up at a local school. The company described Worldcoin as an Ethereum-based “new, collectively owned global currency that will be distributed fairly to as many people as possible,” in exchange for an iris scan and other personal data.

Gunungguruh was not alone in receiving a visit from Worldcoin. MIT Technology Review has interviewed over 35 individuals in six countries—Indonesia, Kenya, Sudan, Ghana, Chile, and Norway—who either worked for or on behalf of Worldcoin, had been scanned, or were unsuccessfully recruited to participate.

Our investigation reveals wide gaps between Worldcoin’s public messaging, which focused on protecting privacy, and what users experienced. We found that the company’s representatives used deceptive marketing practices, and failed to obtain meaningful informed consent. Read the full investigation
