"For example, it would have been interesting to see 20 pictures drawn by girls and 20 pictures by boys, instead she only presented one each." Well, yes, but to me it looked like she was trying to show a typical example from each category. This is a presentation, so the emphasis is necessarily on story-telling, rather than detailed analysis. I would imagine she could have shown a whole load of charts and graphs, but I that would have been rather boring.

"Honestly, I don't believe that girls are always only thinking socially, nice and eco-friendly, while boys dream of guns and bombs." Neither do I. But I think there's a useful point she was making about thinking about the way things interact / what they allow users to do, rather than programs that work fine by themselves but do not play well with others (every morning I load a bunch of stuff and watch them steal focus from each other) and implementing features because it's quite cool that you can do this thing we'll find a use for it later (yay, bloat!).

"Also, where are the campaigns to make more men become school teachers and kindergarden workers?" I don't know. We should probably ought to have some, but expecting them to be provided by the tech industry is a little optimistic.
