There are two thoughts I had while reading this very thoughtful (and entertaining) answer: * The corollary that comes to mind is that the absence of time travelers indicates the relative unimportance of today in history. The author addresses this in her claim that we likely live in the temporal equivalent of flyover country. * Alternatively, time travelers are highly skilled at not revealing their roots as time travelers. My guess is that the second is more likely to be true, but that they are not mutually exclusive (and odds are good that both are true).
