“If all goes well, human history is just beginning. Humanity is about two hundred thousand years old. But the Earth will remain habitable for hundreds of millions more—enough time for millions of future generations; enough to end disease, poverty and injustice forever; enough to create heights of flourishing unimaginable today. And if we could learn to reach out further into the cosmos, we could have more time yet: trillions of years, to explore billions of worlds. Such a lifespan places humanity in its earliest infancy. A vast and extraordinary adulthood awaits.”
― Toby Ord, The Precipice

“The economy of early hominids and that of twenty-first century society have enormous differences, but they do share one important feature: in both of these economies, humans accumulate information in objects. Our world is different from that of early hominids only in the way in which atoms are arranged.”

“all societies have certain needs or desires and they meet these needs by utilizing the resources in their environments. The ability to utilize those resources changes as their knowledge of their environment changes. In particular they develop knowledge of the properties of the resources in their environment and how the resources in their environment can be used to meet human needs and desires. Human knowledge of the resources is dynamic; it changes over time. Greater knowledge of the properties of the resources in the environment allows new ways in which human needs can be meet by exploiting resources in the environment. Our knowledge of our environment grows in a particular order; certain knowledge will inevitably be discovered before other knowledge. The order of our discoveries about nature determines the order of technological change and scientific discoveries in human society. The order of our discoveries of both the properties and structure of nature depend upon the relationship between nature and us. We discover these things in an order from that which is closest to us, to that which is further away, or perhaps in an order from the simplest to the more complex. It is the structure of the universe and our place in it, which determines the order in which our knowledge of nature will grow and this determines what technological and scientific options are available to meet our needs and desires.”

“The key to understanding the course of history is to divide history into two parts. One part follows a predetermined direction and the other part is random and unpredictable. The part that follows a predetermined direction is the part that results from ever increasing human knowledge of the world we live in. The world we live in is structured and understandable and is explained by the laws of physics, chemistry and biology and the known properties of the particles, elements and compounds that make up our world. Our ever increasing knowledge of these laws and properties of matter comes to us in a predetermined and rational order from the easiest discoveries being made first to the more difficult discoveries being made later.”

“Ever increasing human knowledge is the ultimate cause of the development of human societies from hunter gathering to agrarian to industrial societies. However as human societies change from one form to another, there are substantial changes in the social and cultural institutions of those societies. The different types of societies tend to develop with different population structures, class systems, belief systems, government and legal systems, and different types of economies. The changes to these social and cultural systems are dependent on the prior changes to technological systems and so occur in a particular order as the technological changes occur in a particular order.”
― Rochelle Forrester

“Changes in human knowledge causes changes in technology and through the effect that technology has on the social and cultural systems of a society, the change in human knowledge will affect all elements in that society. Changes in human knowledge may also directly affect the social and cultural systems in human society. Ideas such as biological evolution and cultural relativity have affected human society, without producing any technological innovations. Human history in all its elements will be effected by the increase in knowledge that gradually accumulates in human culture.”
