If people can't cope with the fact, that technology based on statistics correctly classifies males and females, maybe they should just stop using it (and/or create their own thing), rather changing the technology. AI is not biased, but clearly - people are.

I would say that anything has bias (even AI, they exists because of us and our initial preconceptions), but at some point you can't deny the fact that we are all biologically born either a man or woman even if you don't feel like one or feel trapped into the wrong gender.

And even if you're a man or woman, we live in the present where some fashion items or appearances are commonly associated to a specific gender. Those change over time, but don't expect people to associate a style to another gender overnight and AI still have to make these common associations to be useful or relevant to the current time, and they'll evolve too.

Actually, one problem is that it doesn’t consistently classify them correctly. For instance, often classifying men with long hair as women.
