Technology Reminder

From the archives as I watch the snow fall, this photo taken from the U.S. Army's official WW II history (the Green Books) on the Signal Corps. It was in the section talking about the state-of-the-art training required for the technology being deployed into the theater of war.

Remember, that was only 60 years ago. Outside of an IBM Selectric 251, not much call for these techs today.

So what tech skills are you learning -- or over focusing on -- that will be the subject of history books in 10 years?

Or are you focusing on strategies and concepts of communication and seeing the various modes of communication as simply tools to be mastered?
