There are many digital identities that are available to Americans, for example facebook, twitter, tumblr etc. These sites allow you to share personal info about you and your life or can be used as a forum to promote causes in which millions of people can connect and in a sense become your 'virtual friends'. These sites have allowed our world to become interconnected and we can be instantly up to date with the latest news. So in a way social network sites have managed to help America create a 'unified identity' as they are constantly aware with the issues in their society and have more chance of getting the message across.
For future Americans the increase of technology is extremely important as their world will literally revolve around it. In terms of education there are already arguments that the way the children develop have changed and that education needs to be directed to these new patterns of thinking i.e. games that help you learn. In terms of job prospects everything is moving towards the internet and so the types of jobs could change. Therefore technology has changed Americans lives in the fact its more fast paced and social networking has helped with promoting issues and helping increase support in those - for example gay marriage.
