Structural inequality and sexism
Not from what I've seen. I've worked in STEM for over a decade, all of my superiors have been woman. There are many initiatives supporting women in STEM (financially and other wise). The majority of advertised positions in STEM mention having a fair and diverse workforce.
There may still be sexism but it is mocked openly. You know, like in this comic. The very fact that is comic exists and is being upvoted is evidence that the tide has truly changed.
Doors open, come on in.
