We are back! Cathi Bond and Nora Young got together (virtually!) to talk future of retail and carbon footprint. Cathi talks about Showfields, a digital/physical hybrid store in New York, and their new Magic Wand app (via PSFK).  Nora talks about this article from two Université de Montréal professor/researchers on the 'hidden infrastructure' required for machine learning: the carbon footprint of training machine learning applications on lots of data.  Hope you're all well and coping ok!
