In my opinion the evolution of the emojis has taken a fundamentally wrong turn. The introduction of skin, hair color variations, genders, granular selections in things like a family setup and mixing in humans is, in my view, fundamentally wrong.
To me the simplicity of the emojis were their main strength. You want family? Sure, family emoji. But now you have to select genders of parents, numbers of kids, etc. I think this guides the users into the wrong direction to convey a completely different meaning.
Maybe helping the user identify with the emojis more is a goal that people want to reach? I certainly don't. My emotions and context may be culturally flavored but otherwise quite universal and I think emojis should be the same.
