A recent conversation with a friend had landed on an interesting topic: the effects of gender-equal hackathons. Several views were presented:
Computer Science contains a substantial subset of individuals who are attracted to the field because of their increased power over the machine and free entrance to communities that pride thoughts and not looks and behavior. This creates a set of people who are lacking in intra-personal social skills. This set of people intimidate and scare of female developers from the field.
The fact that the current CS community is placed alongside a new group of females creates a new community which will eventually overtake the old one. This is a driving force for gender equality in CS.
