Change isn't always good.In order to progress you have to change but that doesn't make change progress.Things can change to the worse.
Let's take robots as an example.Robots are a change.They can lead into a world that people won't need to work or a world where a crazy man creates and army kills everyone and becomes the undisputed master of all of us.
Changes gives progress but not always.
Communism was a change.Did it help the nations who embraced it?
I don't think so.
