I wrote a short story with something of a transhumanism theme. People can read it here. Actionable feedback welcome; it's still subject to revision.

Note: The protagonist's name is "Key". Key, and one other character, receive Spivak pronouns, which can make either Key's name or eir pronouns look like some kind of typo or formatting error if you don't know it's coming. If this annoys enough people, I may change Key's name or switch to a different genderless pronoun system. I'm curious if anyone finds that they think of Key and the other Spivak character as having a particular gender in the story; I tried to write them neither, but may have failed (I made errors in the pronouns in the first draft, and they all went in one direction).
