GRANDMA’S HOUSE, Saigon, VN. Day 4. Finally arrived in Vietnam in the early morning. One of the things that surprised me the most was how much the digital infrastructure has changed in Saigon, yet the buildings themselves have remained unchanged since my parent’s childhood (1940s-50s). The last time I visited was in 2007, when Facebook had just started, when I didn’t even own a cellphone and had to resort to internet cafes to get access to the rest of the world. Fast forward eight years to 2015 and everyone now has a smartphone with handheld internet, Uber for taxis and mopeds, and the ability to FaceTime thousands of miles anywhere in the world in the palm of your hands!
