I fear sf reflects the attitudes of the society that produces it, so it's hardly surprising that Professor Keiko Ishikawa O'Brien gets demoted to wife, mother & primary school teacher, not to mention thing in the way of Miles' friendship with Julian. I do get bitten with Keiko bunnies from time to time, but they tend to die for lack of understanding the roots of the Japanese culture from which she originates. I wish she'd had screentime with Dax, as they're both exo-biologists.
