*nods* I think some of this is a language thing, English now only has "It, Them, One, and They" as pronouns that aren't gender specific. In contrast with some other languages where there is a lot more flexibility in this area. Then the inner unknown bias to associate people with one gender or another without thinking it.
But yeah, Watching the entire video it's more about trying to make a more "vague" gender option, which ironically (or maybe intended) the end clip shows how far away from that we as English speaking people are.
