David, Joanna and Christopher talk about the bizarre non-launch and Joanna's non-review of the Samsung Galaxy Fold, and what it means for the future of foldable phones. Then, WSJ reporter Shalini Ramachandran comes on to talk about her story on how Netflix and other streaming services are putting a serious dent into peoples' sex lives. In this week's Today I Learned, Christopher explains why nobody believes Elon Musk's statements about robot taxis and fancy new chips. Finally, David interviews Oleg Stavitsky, the CEO of a company called Endel that makes algorithmically-generated soundtracks for your life, about how a computer can learn to make music and whether every aspiring rock star should be nervous.
