Sleep wearables are training AI on your brainwaves without explicit consent

An investigation by Science with the Pulitzer Center's AI Accountability Network found that neurology companies have accumulated tens of millions of hours of EEG recordings from sleep wearables and some are using them to develop brain foundation models, despite initially failing to spell out that use in their privacy policies. Interaxon, maker of the Muse sleep and meditation headband, has trained an AI model on about 50,000 hours of EEG recordings and says it removes identifying information such as names, emails and addresses before use. Its Chief Marketing Officer Nadia Kumentas said the company aims "to use as much of that eligible corpus as possible."
