I agree wholeheartedly that it's about getting things done, and is what the universe cares about. As individuals we enjoy being in flow, and when the nature of the work changes we may lose our flow and shake our fists in frustration...

Change can be painful, but that's because it takes energy.

From particles to atoms to cells to people to civilizations, it seems like the whole point is to get more stuff done. Why? Probably because getting stuff done is more interesting than the alternative.
