In the context of this thread, I thought: if I don't want the machine to presume male or female, than what do I want it to do? he/she was what I came up with, but this does not address non-binary gender or fluid gender, weaknesses which were on my mind.

Curious, I looked for guidelines and the best I could come up with was this, which seems helpful if you know the person in question, but not so much if you're referring to someone completely unknown: https://en.wikipedia.org/wiki/Third-person_pronoun#Transgend...

I welcome advice.
