About a year ago I came across the work of the historian and archaeologist Ian Morris, who observed that "change is caused by lazy, greedy, frightened people looking for easier, more profitable, and safer ways of doing things". This Morris Theorem essentially presents human sloth, greed, and fear as the key drivers for our society's appetite for change – change of our environment to our own benefit. That is what we call innovation: the purpose is an easier, richer, safer life for all of us.
