During a Thursday performance at Madrid's Mad Cool Festival, singer-songwriter Lorde delivered a blunt verdict on wearable technology, saying between songs, "Can I just say, for the record, fuck the glasses. Don't get the glasses. Not sexy." Lorde did not name Meta, Ray-Ban, or a specific pair of AI-enabled glasses. Representatives for the singer did not immediately respond to Business Insider's questions. The setting gave the remarks subtext, as Ray-Ban sponsored the festival and promoted its smart glasses there, and Blackpink singer Jennie, a Ray-Ban Meta ambassador, performed on the same stage after Lorde. Meta has emerged as an early leader in AI wearables through its partnership with EssilorLuxottica, which said it sold more than 7 million AI glasses across its Ray-Ban Meta and Oakley Meta lines last year. The $299 glasses can answer questions, play audio, and capture live photos and videos, but have faced pushback from privacy advocates. Lorde, who has walked the Met Gala red carpet four times and was on the cover of Vogue in 2021, previously told The New York Times she tried ditching her phone after becoming alarmed by how much time she spent looking at its screen.
