If you use your Ray-Ban Meta smart glasses all the time you might want to be careful of what you're snapping pictures of, and what you're asking Meta AI, through them, as Meta has confirmed that it may use these visual and audio inputs to train its smart assistant.

Two Harvard students have created an eerie demo of how smart glasses can use facial recognition tech to instantly dox people’s identities, phone numbers, and addresses. The most unsettling part is the demo uses current, widely available technology like the Ray-Ban Meta smart glasses and public databases.

Other updates coming to Ray-Ban Meta Smart Glasses include the ability to voice control Spotify and Amazon Music through the device as well as new integrations with apps like Audible and iHeartRadio.
