World Usability Day is happening on November 14, 2019, and we in large part have Elizabeth Rosenzweig to thank for it. Listen to Elizabeth describe her journey from taking pictures in Vermont and a rejection from RISD and to the MIT Media Lab. We also talk about the relationship between user experience and customer experience, who stands supreme in that arrangement. Finally, hear us discuss about how usability can change the world, and how the first UX professional was likely Homo Habilis.
