"People, for the most part, are not playing with their software because they want to. They're using the software as a tool to accomplish something else that they would like to do. Maybe they are using a chat program to try and seem witty, in hopes that the person they are chatting with will want to spend time with them, so that, ultimately, they have a better chance of getting laid, so that, ultimately, their selfish DNA will get to replicate itself."
