I do think that there is an interesting twist for humanity though as we try to move into a virtual space. Much of the social norms that are hard wired into people to allow us to get along involve actual facial and other cues only accessible in person. It will likely take some training and some time figure out how to deal with each other remotely. There is a lot of work in psychology looking at things like "social identity theory" that people have applied to internet interactions (with some colorful summaries [1]).
I do think that many folks will be surprised in the future to find that the internet isn't quite as anonymous as they think. There are only 7 billion or so of us and google and others could process everything we've ever written in an afternoon. Certainly a lot of folks have been surprised to find that their emails aren't very secure and can hang around for a long time. If you wouldn't say something to somebody in person then it usually isn't a good idea to say it online as well with possible exceptions for concern for your own personal safety when constructively criticizing the powerful.
