They can write good short bits of code. But they also often produce bad and even incorrect code. I find it more effort to read and debug its code then just writing it myself to begin with the vast majority of the time and find overall it just wastes more of my time overall.
Maybe in a couple of years they might be good enough. But it looks like their growth is starting to flatten off so it is up for debate as to if they will get there in that time.
I am not sure you can conclude that. Environmental factors likely play a large role here as well as genetic factors. I feel we tend to idolize and sexualize the female form far more then the male form these days. But if you look back and different cultures that did the same with the male form I suspect you would see an opposite trend to both genders preferring the male form more often.
