On today's show: sleep gadgets, AI DJs, and sneaky TVs. Victoria Song joins the show to talk about her experiences with the Eight Sleep mattress pad, the Oura Ring 4, and other sleep gadgets. Can you really measure your way to a better night of sleep? After that, Allison Johnson gives us her take on Spotify's AI DJ, and we wonder exactly how an AI tool is supposed to help us find and listen to music. Finally, Nilay Patel comes on to answer a question from the Vergecast Hotline about the Samsung Frame TVs — and how to figure out whether you need a TV at all.
