While not related to the topic of women and computing as much, I have noticed the stupidity trend over recent years too. You guys should check out this movie "Idiocracy", where an average Joe from our time is frozen and wakes up in the future where everyone in the world is stupid and he's now the smartest man alive. Or this TV series "Nathan Barley", which pretty much sums up how it is now, and what it's like living in a world of idiots.
As for girls using Amigas, I think the best thingg to do is just find a girl who's open minded and introduce her to Amigas and all the great games and creativity software. Don't get your hopes up finding too many girls who already have Amigas, they exist but they're rare. If we want more girls using Amigas, we just have to make them.
