Revolutionary remediation

Over the last decade so much has been remediated. We can look at the telegraph, telephones, books, and literacy itself. The invention of the telephone remediated communication in itself, and has continued to remediate itself over time. This form of communication has transformed from the party line, to dial tone, to push button, to cordless, to wireless. We not only talk on our phones, but we text, watch television, surf the web, compose documents, and the list goes on.
We can also say the same for written communication. Seldom do we sit down and write a letter by hand using pen and paper. Email, the web and social networking sites have replaced pen and paper.
Are there any forms of remediation that are truly revolutionary? I suppose I consider the Internet revolutionary. After all, it has change we conduct business, teach classes and basically communicate. This form of communication has also eliminated some stereotypes and racial and ethnic barriers. We communicate, play games and conduct business real time with individuals across the globe.
As time goes on, I believe the term literacy will be redefined. It will no longer be the ability to read and write, but the ability to navigate, communicate, interact as well as read and write in a new digital world. Only time will tell, but if you are not able to communicate digitally, you are missing out on the transforming world we live in today.
