Everywhere we look, we see screens. The other day I watched clips from a movie as I pumped gas into my car.

The oral skills of memorization, recitation and rhetoric instilled in societies a reverence for the past, the ambiguous, the ornate and the subjective. Then, about 500 years ago, orality was overthrown by technology.

A Hollywood blockbuster can take a million person-hours to produce and only two hours to consume. But now, cheap and universal tools of creation (megapixel phone cameras, Photoshop, iMovie) are quickly reducing the effort needed to create moving images.

With the rise of life (in our immediate neighborhood) information ascended in influence. The informational process we call life took control of the atmosphere of Earth several billion years ago.

Extropy is neither wave nor particle, nor pure energy. It is an immaterial force that is very much like information. Since extropy is defined as negative entropy — the reversal of disorder — it is, by definition, an increase in order. But what is order? Despite our intuitive sense, we lack a good operational definition of order, which seems to be tied up with complexity (see Ordained Becoming). For simple physical systems, the concepts of thermodynamics suffice, but for the real world of cucumbers, brains, books, and self-driving trucks, we don't have useful metrics for extropy. The best we can say is that extropy resembles, but is not equivalent to, information.

For four billion years evolution has been accumulating knowledge in its library of genes. You can learn a lot in four billion years. Every one of the 30 million or so unique species of life on the planet today is an unbroken informational thread that traces back to the very first cell.
