Some people (optimists like some economists) are confident (overconfident?) about human . They think that human can solve any problem as long as there is a need. This perception formed may be due to the industrial advancement (standard of living, science and technology, better institution) since the last few centuries. But can we attribute it solely to the human ingenuity? Why human did not achieve the great leap earlier (note that human has already been evolved to this current form since at least 50,000 BP, before the last fews centuries human history keeps showing rise and fall of the civilizations)? Some other people argue that rising of current civilization is mainly due to high EROI of fossil fuel. I cannot judge because I think it is hard to identify the root causes in an unrepeatable process like this.

While I have no plan to talk about reasons of rising of current industrial civilization in this post, it is a good example to show that how poor our knowledge be. While we can send people to the moon, we cannot eradicate war, hunger, AIDS, traffic jam; we still struggle in developing technology that can recognize people’s face un-intrusively and flexibly under natural environment like human does; or we cannot even predict how the water level of a bathtub change. There are lots of examples you can think of about what human still cannot do presently, even there is a will (e.g. forecast direction of winds that bring the volcano ash).

The most critical evolutionary constraint on human is to understand complexity (complex means difficult to understand, so a thing will not be called complex if we can understand it). For example, no one know for sure what will happen in the current Euro financial crisis. What if we let Greece bankrupt? What is the consequences (especially unintended consequences) of current decision to bail it out? We grow our civilization to this state of complexity but we don’t know how to manage it. In a world of changing faster and faster and becoming more and more interconnected (interdependence), we just realize how poor our ability to control it to achieve the vision we want.

This is my thought after reading this post:

The ultimate challenge for humanity, then, is to figure out how to make insight about complex systems evolutionarily successful.

At least, we need to recognize that we still ignorant of many things. We should be more humble. We should be more careful. We should be watchful about where our current direction leads us to be, and rethink the actual relationship between economic growth and human development. So I think the first step should be raising awareness about our poor ability to learn complexity (especially dynamic complexity).

If you think this is not an issue, then ask yourself: Are you happy? Do you feel your life is full of happiness? If not, why? Do you think you are happier than people before the industrial civilization? Or more simple question, happier than people who died before the internet has invented? You enjoy so many modern innovations, you should be much happier than them. If not, this is a sign of unhealthy development. Development should increase people’s happiness, not less. Let’s think about it.
