He can use it as a defense, but trust me, I am not defending him.
What I am trying to say is that in some industries the inequality is in the market. Whoever manage to balance it is doing it by putting down a lot of money and providing extra benefits (such as quick career progression). This means that whoever is not ready to do so will end up with a very imbalanced distribution. Musk has demonstrated that his focus is saving money, which is probably also one of the reasons he is ending up with only men. There are for sure others, but I believe it makes sense to consider the overall market.
To “overcome” the imbalance, you cannot really do it on the current market, because it is already imbalanced. What you have is companies that fight for a small pool of available employees, some will meet a decent diversity (with effort and money) others won’t be able to do so.
The problem has to be solved before, at a cultural level. As I said in another comment, for instance this imbalance is not a problem in pharma, where data science is probably majority women (I don’t know the stats, but this is my anecdotal experience). There is a cultural issue with women in tech that can be solved only with cultural changes and with generational change. Already z gen is in a better position than millennials or x gen. But more needs to be done
