Progress in efficiency of labor is necessary in order for us to pursue more challenging endeavors. If it still took 18 humans to produce food for 20 humans, then we wouldn't be as far along as we currently are. As it stands, due to technological advancements, it takes about 2 humans to produce enough food for 20 humans, which allows the other 18 humans to pursue other interests, like quantum physics or whatever. That is the kind of progress I am talking about.
And we need to see it in the energy sector, and everywhere really.
There's no need for humans to be doing work that isn't necessary.
