It's remarkable that they would put together this piece, state that they are "test[ing] new systems through the lens of inclusivity" and then immediately, proudly show a chart of their new system that specifically leaves no room for non-binary or transgender people. It's like they are going out of their way to say they will be inclusive with AI in regards to race but gender? No they will exclude people from this, anyone who identifies or presents as neither the binary male or female will be specifically excluded from being able to correctly this system.

Yes it's nice that they write "gender presentation" rather than just "gender", as they know that is what they are trying to measure. But then why not let it train for "nonbinary" as well?

Facebook can try as hard as they want, but their inherent bias against minorities will still show through.
