Dont get me wrong, they sure exist, however not enough of them to fill any sort of meaningful quota. I have one female colleague in the department and she is very annoyed to be begged to be the token female. And not at all interested.
It was somewhere along that road that it dawned on me that i have yet to meet any female colleague in computer engineering who thought any sort of quotas to be a good idea. They are obvious nonsense implemented by people who never in a thousand years would think about about going into that profession themselves. You cant use them to force people into existence. And outside of kidnapping first semester Psychology or MBA students there isnt much reason to be optimistic for quotas in the future.
