Can you share why these statements are controversial?
They might be misguided or misinformed, but the underlying fact is that women are not as well represented in stem. Just because the reason it's more likely to be misogyny rather than any biological inclination, doesn't make it an outrageous statement in my opinion.
Because as a statement is functions to excuse the representation in the field.
It completely neglects the actual history of the field of computing, even just the 20th century, where the field was filled with women.
It’s only once it became a prestigious field that women suddenly developed a “biological” inclination against it.
The difference in participation within STEM between men and women is not well explained by biological differences. Blow has repeatedly claimed that it is actually the primary factor and seems actively disinterested in other explanations.
This is "controversial" in that it's a position that is not well supported by evidence and he has repeatedly used his platform in the past to make unsupported claims to the contrary.
