Ultimately I think there ought to be a fundamental debate about what "changing the world" even means in the context of the tech space. In other words, how big does a company have to get to "change the world"? How much reach? Can it be drawn to a hard number? A specific metric? Or is it this nebulous sort of thing that doesn't really mean anything?

I think we’d see a pretty wide range of opinions if we polled folks here as to which of the current crop of both established companies & startups they felt were companies that really, truly “changed the world" or were in the process of doing so.
