The 21st Century’s Most Important Idea… & Older Natural Algorithmic Forces

1. “The 21st century will be dominated by algorithms,” says Yuval Harari. That makes “‘algorithm’ arguably the single most important concept in our world.”

2. He’s almost right. Natural algorithms have ruled every century with life in it. He means unnatural algorithms (which have been called “weaponized math“) now matter.

3. Daniel Dennett says, “Darwin discovered the fundamental algorithm of evolution.” Of course Darwin couldn’t have seen natural selection as algorithmic, but technomorphic analogies to our unnatural computers mean we’re beginning to recognize “algorithmic forces.”

4. For instance, Gregory Chaitin says, “the origin of life is really the origin of software,” and “DNA is multibillion-year-old software.”

5. Algorithms are sequences of step-by-step instructions for complex processes (like recipes, or software). They describe how dumber sub-steps compose complex tasks.

6. Evolution’s survival-of-the-fittest algorithm is very loosely “survive, replicate with variation, repeat.”

7. Out of that dumb process-logic arises all the intelligence and complexity of all living systems. Including what Dennett calls “competence without comprehension.”

8. Consider “termite castles” that look like a monumental Gaudí…
