Memory has definitely changed with the advent of technology. The ability to acquire information almost instantaneously has definitely reduced the need to remember more information. Also, I feel that social interaction has changed due to instantaneous communication. People expect others to instantly reply at any time and be available at all times. I know this is a cause of increased stress (http://scholarsarchive.jwu.edu/mba_student/12/) in the work place and a blurring of tradition work/home life boundaries.
I think the permanence of technological communication is also causing problems and changes in social skills. With the internet, anything that is posted can potentially be recovered at any point in the future. Never before has a form of communication been needed what would instantly delete itself (snapchat, privnote), at least in any other setting than a military one.
Technology particularly the internet and the multitude of television channels have made it easier and easier for extreme views to flourish. Even if you have views that would be considered immoral, wrong, or evil by most people it is easy enough to find groups and people who share your own ideas and views, as well as exclude anything that does not fit your view. Take the fact that certain news channels cater to certain ideological standpoints (fox news, Cnn, etc). No longer do companies need to cater to a middle point or showcase opposing views. The internet even changes based on your beliefs without you knowing (http://www.technologyreview.com/view/522111/how-to-burst-the-filter-bubble-that-protects-us-from-opposing-views/).
Technology has also greatly changed how we speak and talk, for instance I hear people saying "lol" or Oh-Em-Gee on serious news channels.
At LW London last week, someone mentioned the possibility of a Google Glass app doing face recognition on people. If you've met someone before, it tells you their name, how you know them, etc. Someone else mentioned that this could reduce the social capital of people who are already good at this.
A third person said that something similar happened when Facebook started telling everyone when everyone else's birthday was. Previously he got points by making an effort to remember, but those points are no longer available.
Are there other social skills that technology has made obsolete? And the reverse question that it only just occured to me to ask, are there social skills that are only useful because of technology?
I'm not really sure what sorts of things I'm looking for here. "Ability to ask for directions" seems like one example, but it feels kind of noncentral to me, I don't know why. But I'm mostly just curious.
