Earlier quoted context omitted.
Sometimes people claim that women are biologically, statistically, just not as good/interested as men at programming/technology, and point to current gender balance in tech as evidence of this ("There's a reason there's lots of male programmers, men must be just better!") Remembering some of these women, and the early history like this, is very relevant today to show that that's nonsense.
It's not nonsense. Modern women are statisticaly less interested in programming. That's because boys 20 years ago got c-64 or PC because they wanted to play games, and girls 20 years ago got barbies. Turns out barbie doesn't have the same side effects.
Though while this might be large enough to be considered statistically relevant, nothing I've seen suggests a natural bias strong enough to account for more than a fraction of the mis-balance we see in later life in the science & technology arenas, so social pressure (even "accidental" pressure due to, as you suggest, the "toys" parents and other family buy), both at a young age and as kids progress through school, are presumably the larger factors by quite some margin.
There are natural gender biases, mental as well as physical, that are not caused by external cultural pressure, and to completely disregard that would be a mistake. But I think (caveat: going by my experiences here rather than any scientific study) in most cases that the difference between the average man and the average woman is smaller than the range of differences within each gender (so if you consider only the bulk of the population it might be valid to consider us identical overall).
