Life 3.0

Quotes

1. Let’s instead define life very broadly, simply as a process that can retain its complexity and replicate. What’s replicated isn’t matter (made of atoms) but information (made of bits) specifying how the atoms are arranged. When a bacterium makes a copy of its DNA, no new atoms are created, but a new set of atoms are arranged in the same pattern as the original, thereby copying the information. In other words, we can think of life as a self-replicating information-processing system whose information (software) determines both its behavior and the blueprints for its hardware.

2. 

   How is technology changing the hierarchical nature of our world? History reveals an overall trend toward ever more coordination over ever-larger distances, which is easy to understand: new transportation technology makes coordination more valuable (by enabling mutual benefit from moving materials and life forms over larger distances) and new communication technology makes coordination easier. When cells learned to signal to neighbors, small multicellular organisms became possible, adding a new hierarchical level. When evolution invented circulatory systems and nervous systems for transportation and communication, large animals became possible. Further improving communication by inventing language allowed humans to coordinate well enough to form further hierarchical levels such as villages, and additional breakthroughs in communication, transportation and other technology enabled the empires of antiquity. Globalization is merely the latest example of this multi-billion-year trend of hierarchical growth.
