Demographics might differ for AI researchers or other STEM fields adjacent but in general it seems odd to be surprised when it's literally how things have been for at least decades.
Not saying this is a good thing, that I know why it is like this, or what should be done if anything, I have no idea. But why act surprised? The gender ratio is super off balance for a lot of jobs. My career isn't that long but across four jobs, as far as I can remember, the ratio has remained about as skewed as publicly available metrics suggest it would be, not that I personally pay all that much attention.
I'm not trying to suggest in some roundabout way that this is good or even not bad, but it is rather arbitrary. In truth, "one person" rarely does anything, since in many senses, all of us stand on the shoulders of giants. But, even then, the accomplishments of individual people have been pretty impressive. There are singular people who have discovered the nature of a lot of things despite only having one perspective to bring on their own.

Provide other data if you think that's wrong.

Which doesn't cite its source directly, but it's probably the Stack Overflow developer survey:

Admittedly, that's not a great source for objective information since it is going to be skewed by the demographic that is responding.
However, this is the first time I'm hearing that the number is as high as 20%. In my career, the most women on the same team as me was literally 1, as far as I can remember.
Why does my experience differ so much?
