Change is occurring at a pace unprecedented in history.
For example, the Roman Empire essentially used the same military strategy to create its empire over 700 years with little modification, a successful model that had longevity. By contrast, military technology today is changing at lightning speed. It’s not that long ago that ‘drone warfare’ entered our vocabulary and enabled a ‘pilot’ to sit in an office in Arizona and fly missions anywhere in the world. The next step will be ‘drone warships,’ removing the need to have crewed ships.
Change is no longer a matter of choice. If you fail to change you will be left behind.
