That. We still don't know what long-term exposure to highly condensed, highly customized information does to our brains and social systems as a whole. For example, there are signs that social network users are actually unhappy - in other words - are experiencing all kinds of mental health issues. It is well known that programmers experience "burn outs", which, from personal experience, is a terrible and debilitating state sometimes even leading to suicide. There is addiction to gaming, chat, porn, social networks. Mobile phones have exposed everyone to the infinite stream of information/communication and I think this will lead to many more mental health issues. I think we are not yet prepared for the kind of impact that current and future tech will have on our minds, so this would be a worthy field to invest in now.
