Artificial intelligence (AI) has become one of the defining technologies of what economists and policymakers describe as the Fourth Industrial Revolution. This is an era in which digital, physical, and biological systems are increasingly intertwined. In practical terms, AI refers to computer systems capable of performing tasks that typically require human intelligence, such as recognizing patterns, learning from data, making predictions, and assisting in complex decisions.

The internet is rife with anonymous accounts as users adopt pseudonyms, sometimes for genuine reasons like speaking freely, and other times for nefarious ones. But this era of online privacy could be coming to a close. In a study available on the arXiv preprint server, researchers demonstrate that large language models (LLMs) can identify the people behind these accounts at scale.

Artificial intelligence models can now clone a voice with just a few seconds of audio, fueling a surge of deepfake songs online and creating a growing crisis for musicians who don't want their voices hijacked. Beyond the obvious intellectual property rights issue, this can lead to lost revenue and take an emotional toll on artists who put their heart and soul into their songs. But researchers now have a solution.

Anthropic, a leading AI company, recently refused to sign a Pentagon contract that would allow the United States military "unrestricted access" to its technology for "all lawful purposes." To sign, Anthropic CEO Dario Amodei required two clear exceptions: no mass surveillance of Americans and no fully autonomous weapons without human oversight.
