I'd personally like to see more gender non-conforming roles in societies.
In a society with magic or space tech, why does there need to be a coded gender for certain jobs?
This goes for 'character classes' too. I'd love to see more healer archetypes that are cis male, or wizard types that are black or brown without relying on stereotypes.
I'd also like to see more of that in occupations too. Why not have a union of earth magic construction workers who happen to be mostly women in one city?
What about the rest of you? What cool things would you live to see in sci-fi/fantasy?
Iirc in the Culture "human" is just a series of checkboxes for your morphology and there's loads of aliens that don't look that way and have their own morphological kindred.
