The more I use this software, the more I begin to consider how it will impact reading and writing instruction in the future. So on one hand you have an evolving tool to assist writers. On the other you will have software that reads for you.
I am not sure exactly when the transition will take place, but I can't imagine a classroom in 2100, or MUCH sooner, that will address literacy the way we do today. Most of the barriers to literacy should be overcome by then. It seems as though most of the emphasis will shift to reading comprehension and ultimately the application of knowledge since the acquisition of knowledge will be a given.
Just as Gutenberg's printing press led to the Enlightenment, I believe technology that provides literacy for all will lead to a 2nd Enlightenment where, for the first time, no child will be left behind.
