Irreverent account of the invasion of the digital age as seen through the eyes of one small, shell-shocked being. From the early days of room-sized mainframes running on Fortran to present-day addiction to Instagram and Netflix, humanity has gone through mind-blowing changes in its love affair with technology. It's a helluva story and should not be told without a sense of humor. Fortunately Sue Lange lived through it all and brings on the funny. This is not your grandmother's memoir. If you're a fan of Ellen Ullman and "Life in Code," you will love RTFM.
