@maxdancona,
A force applied over a distance refers to energy spent to achieve a goal complete a task get into an objective. So "energy efficient" totally applies.
Same goes for computation, the least amount of steps to complete a task, again energy efficient. How come you just don't relate words??? Its just like an impossible task for your brain architecture...could it be some form of linguistic autism? I wonder seriously...
Now lets make these crystal clear so that children can understand it!
You could build a space rocket over a sequence of many lifetimes and that includes gathering the resources and making the materials, project assemble, and a 1000 years of thinking about how to do it alone in the desert without any social background on ideas or cultural tech wisdom to back you up. For the purpose of the thought experiment lets say I give you a youth pill so you can live that long.
We could gather 10.000 thousand men and put each one alone to work and compete and wait 1000 years to see which one would come up with the best project in the end if we could get one at all to get it done which I highly doubt.
A more productive way to do it goes with cooperation and a social contract that ensures a minimal amount of fairness so people are willing to trade cooperation and specialized know how to achieve the task if they feel the pay off is fair enough and benefits everyone in the end.
To complete the task which one of these methods is more energy efficient eh?
And there you go now you know why cities look like computers seen from an air plane and why civilization is not an accident and why Moral behaviour is the cement that keeps us all alive.
A society that does not cooperate in an energy efficient manner is doomed to fail dissolve and go extinct!
Moral Realism simply states what Science always defended in all other fields. That there are objectively more efficient and less efficient attempts at cooperating in a very complex system. Which in turn means that there will be natural selection and convergence on the most efficient algorithms for proper cooperation. The ones that endure tend to have the same overarching structure. Done, you have Universality without loosing diversity!
