On twitter yesterday someone asked Alexa what a woman is, and Alexa answered that a woman is an adult human female, when younger than an adult a girl and then went on to explain about X chromosomes.
Since I got my echo a couple of years ago I have periodically asked 'What is the difference between sex and gender?', for years she has told me they are the same, but yesterday she didn't. She said sex refers to characteristics etc and gender is how someone identifies.
It wasn't perfect but she's getting more terfy by the day.
