Are men there not impacted in the same way?

Point being it is too complicated to nail down a biological factor that was determined from birth.

No culture is completely free from environmental influence. As we age, the influences from our youth act like compound interest. These can change the way we think. Nurture impacts nature, and vice versa. The generally accepted view these days is the process is cyclical,

"neurological traits develop over time under the simultaneous influence of epigenetic, genetic and environmental influences. Everything about humans involves both nature and nurture" [1]

Men are impacted the same way. The argument in the memo is that (1) tech jobs are passion jobs for men to a greater degree than women, hence in societies where people are more able to follow their passion you'd see relatively more men in tech (2) men compete on financial success to a greater degree than women, even if this is not required for survival, so in affluent societies you'd see relatively more men in tech. This would explain why the difference is greater in societies where there is less economic pressure, even though those societies are on average more egalitarian.
