Tipstaff, I know where you're coming from, because I think like that as well. Everything is relative. However, with that in mind, I also have the life experience to know the probability of a context and what people are most likely asking me. When someone asks you what a browser is, the hands-down, more-than-likely context will be an internet browser such as Firefox, Chrome, and the devil spawn IE. Not to mention if someone on the street did actually mention something such as a "data browser" or file browser, they would have probably asked or had been given some clarification. Certainly if any of that came up at all, Google wouldn't have put it into the final cut that we just watched, as it would confuse anyone watching it and muddle the flow of the video. Yes, everything is contextual. I've gotten into straight-up arguments with people on many occasions and, in my opinion, I was right, because I played that card. But at the core of things, most people only think of one context when asked "What is a browser". Always go with best-case.
