Imagine for a moment you are a child in 1941, sitting the common entrance exam for public schools with nothing but a pencil and paper. You read the following: "Write, for no more than a quarter of an hour, about a British author." Today, most of us wouldn't need 15 minutes to ponder such a question. We'd get the answer instantly by turning to AI tools such as Google Gemini, ChatGPT or Siri. Offloading cognitive effort to artificial intelligence has become second nature, but with mounting evidence that human intelligence is declining, some experts fear this impulse is driving the trend.

A March 20 article in The Atlantic served as the letter's impetus. It reported that Meta had used LibGen, a pirated collection of over 7.5 million books, to train its AI models. Anyone on the internet over the last few weeks has likely seen videos of distraught authors learning that their work is available on the database (and potentially used by Meta without their permission). A lawsuit in the US alleges Meta CEO Mark Zuckerberg approved the use of LibGen's data to train its AI. The lawsuit's plaintiffs include writers Sarah Silverman and Ta-Nehisi Coates.
