Hexagons are really not better than triangles.
I kinda do agree with out on fractal geometry though, (although you’re gonna see a lot of tiny triangle shapes). And also for certain applications, things like catenary curves are ideal.
I don’t think 90 degree surfaces are going anywhere though. Having angled walls would be less space efficient, and angled floors would be a safety hazard. And cubes/rectangles are by far the easiest, most compatible shapes to efficiently design with. Although in your hypothetical future I guess we can just use the biocomputer superintelligence to design everything.
Personally, I like they/them better. It’s already been used for persons of unknown gender for a long time, and using it as explicitly non gendered is really seamless.
Wheras neopronouns can feel very attention calling and othering. Then there’s the issue that most of them sound gendered anyway, (‘zhir’ sounds a lot more like ‘her’ than ‘him’)
I do agree about the need for more nb representation, though.
