I know many fine sysadmins and network engineers that couldn't code anything to save their lives. Coding is one of many ways to contribute in IT, and a lack of coding knowledge doesn't preclude one from understanding how technology works. Conversely, I have met several programmers that have a surprising lack of understanding of anything that goes on outside their code. Teaching everyone to code will not magically prepare them for the future, nor will a lack of coding knowledge prevent them from functioning in a high tech society.
Now, making technology a bigger part of the curriculum? I think that is a good idea.
