Revolutionizing?

A comment was raised earlier in relation to one of the presentations that got me thinking. One of the participants wondered what was revolutionary about one of the presentations.

The point of this post is not to judge the merits of that comment in relation to the content that it critiqued, but rather to look at the nature of revolutionary events.

The question I would ask is, does a revolution occur only when the wheel is reinvented? Must we have entirely new things (things that have never been seen before) in order to have a revolution? I don't know the answer to that, but I firmly believe that we don't need to throw out everything that was done before to be successful going forward - in fact, I suspect that this would be extremely counterproductive. The revolution may be in taking lots of little things that have been successful in the past, and bringing them under an umbrella that allows them all to work more efficiently together.
