Lorde criticized AI smart glasses at Mad Cool Festival in Madrid on July 9, calling them "not sexy" and saying "Fuck the glasses." While the context strongly suggests she was referring to Ray-Ban's Meta AI smart glasses, she didn't explicitly name the product. This reflects broader backlash against Meta's smart glasses, with some users changing how or whether they wear them amid privacy concerns and the devices' unpopularity at cultural events. The comment matters because major artists criticizing consumer tech products in public venues can influence adoption rates and brand perception, especially among younger audiences who attend festivals.
