1. The 21st century will be dominated by algorithms, says Yuval Harari. That makes algorithm arguably the single most important concept in our world. <\/p>\n
2. Hes almost right. Natural algorithms have ruled every century with life in it. He means unnatural algorithms (which have been called \"weaponized math\") now matter. <\/p>\n
3. Daniel Dennett says, Darwin discovered the fundamental algorithm of evolution. Of course Darwin couldnt have seen natural selection as algorithmic, but technomorphic analogies to our unnatural computers mean were beginning to recognize algorithmic forces. <\/p>\n
4. For instance, Gregory Chaitin says, the origin of life is really the origin of software, and DNA is multibillion-year-old software. <\/p>\n
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. <\/p>\n
6. Evolutions survival-of-the-fittest algorithm is very loosely survive, replicate with variation, repeat. <\/p>\n
7. Out of that dumb process-logic arises all the intelligence and complexity of all living systems. Including what Dennett calls competence without comprehension. <\/p>\n
8. Consider termite castles that look like a monumental Gaud church. Termites collectively have the competence to build complex castles without comprehending what theyre doing. Smart-seeming higher-level competence and complexity are caused by following dumb lower-level steps. <\/p>\n
9. Here, its worth noting that evolution exists in a different way than gravity (they differ ontologically). Both cause changes in the world, but forces like gravity operate directly via intrinsic physical properties (having simple algebraic relationships), but evolution is a complex algorithmic force (that emerges and operates indirectly, systemically). <\/p>\n
10. Algorithmic forces exist and exert their powers in systemic and relational ways; theyre not driven by isolatable and intrinsic traits. They require sequential steps, and are built from iterative if-then-else logic. <\/p>\n
11. Another way to say this is that algo-forces are driven by richer information processes than physical forces. In physics a few isolatable numeric variables (like electric charge) capture the relevant phenomena. But abstract (imagined) attributes like fitness in biology cant be measured (and dont exist) in isolation from their context. <\/p>\n
12. Evolutions natural algorithm ran for ~4 billion years to generate us. But Hararis human-generated unnatural algorithms (the kinetic logic built into our culture and technology) are now shaping the biosphere (see the anthropocene era). <\/p>\n
13. That puts us in the termite role. Were building complex higher-level collective structures that we neither intend nor understand. (Thats why were facing a global marshmallow test, and why mindless market algorithms make musical toilets while people starve.) <\/p>\n
14. Evolution and economics are both driven by algo-forces. Theyre both in the productivity selection business, but the currently dominant profit-maximization algorithm often isnt prudent (or survivable). <\/p>\n
