I don't think it's grossly unfair to assume people know the name of the fastest human being in the world. It's also fine not to know, but your comment assumes

I don't think it's grossly unfair to assume people know the name of the fastest human being in the world. It's also fine not to know, but your comment assumes we know who or what, for example, "allegory", "database", "cats" and "misnomer" are. My point is that every discussion assumes some knowledge, and if you lack it you can just look it up, or ask, without making allegories about cats and databases and huffing and puffing about information technology elites.
