I want to experience something magical, and ideally, be ignorant of any gadgets or technology working in the background. When users are accustomed to a rich experience, they are unlikely to be drawn away by the next shiny object that comes along. When I look at companies, I want to be as enthralled by the experience as I am impressed by the technology. Why the dot product? For those who were awake during high school calculus, it’s the inner product of two vectors, which is small/zero if orthogonal, and greatest when they are codirectional. Translation? You’re most advantaged when your technology is focused along a rich user experience.
