In the coming decade I am expecting to see a whole revolution in how a lot of tech works and its social impacts. And the main leader for so much of this change is carbon. Not the stuff that you shove on the fire to stay warm, but the nano-scaled versions of it. Carbon nano-tubes promise to improve everything from how we construct huge buildings, to how computers work, and even how we collect electricity. Flexible screens will be the true beginning to the "everything is interactive" world that society is trying to reach. Whilst 3D TV's will only make us itch more to get true holographic devices (the holographic displays will probably take a while longer...).
I am also hoping to see further improvements with robotics, to the point where they really would be able to integrate into human society. Medical advances will be made possible through prosthesis, and may even become the norm to have a prosthetic organ replaced instead of a donor's organ.
If all of the above sounded out of the question (next year not next decade) its because next year is the beginning of all of this. Along with some more "down to Earth" issues and questions. For example, the Wikileaks issues are asking the tough questions as to where the law stands in the internet, and how information is processed on the internet because of legal changes. The integration of more popular organisations (google, facebook, youtube, twitter, etc) will increase further, whilst other physical devices will try to do the same. We should also expect improved internet connectivity, namely in the environment of wireless technologies.
So long as the political and financial sides of things can catch up, keep up, and accelerate the improvements of tech, next year, and the rest of the decade itself, should be a fun time to ride through.
