This is hilarious, but also: how could anyone develop such a tool and not at least test it out on their own images? Someone with a public persona no less! Boggles my mind.
I mean, I bet they did, but you can't test it with all the photos ever taken of you. Someone probably tried dozens of photos to get this result. Which, to be clear, I admire.
They did, they know it doesn't work, but they are already too far down in the money hole. Gotta grift and bullshit and spread bigotry until they make back the money.
The false result is from some unrelated gender detection tool that has nothing to do with the app. Nothing here indicates the actual app makes the same error.
The post is basically saying "this thing doesn't work because I tried something else and it didn't work".
