How did Division of Labor lead to The Internet?

8 steps · 7 domains · 8,983 years

  1. Division of Labor~7,000 BC (craft specialists) · 7,000 BCSplitting work so each person does one thing well instead of everything badly — the arrangement that turns food surplus into every other profession.
  2. これを必要としたのが—— それを可能にした ↑
    Agriculture~9,500 BC · 9,500 BCTurning a patch of land into a repeating calorie machine by planting and tending chosen crops — the surplus that made cities, writing, and everything after them possible.
  3. それを可能にした ↓

    A dependable surplus of sugar-rich grain, fruit, or honey is the feedstock; foragers rarely had enough in one place to spare for brewing.

    Fermentation~6,000 BC (widespread); chemically attested by ~7,000 BC · 6,000 BCLiving microbes — chiefly yeast — eating the sugars in grain, fruit, or honey and excreting alcohol and carbon dioxide. Humanity's first controlled chemistry, run entirely by organisms no one could see.
  4. これを必要としたのが—— それを作れるものにした ↑

    Fermentation needs a vessel that holds liquid for weeks and can be sealed against air — the first job of the sealed jar.

    Pottery~18,000 BC · 18,000 BCClay shaped by hand and hardened in fire — among the first materials humans transformed permanently into a new, durable substance, giving them sealed vessels that could store food and, above all, boil it.
  5. それを作れるものにした ↓
    Glass~1,500 BC (vessels) · 1,500 BCSand melted with a flux of soda or plant ash until it fuses into a transparent solid — shapeable while hot, rigid and chemically inert forever after.
  6. それを可能にした ↓
    Lenses~1286 AD (spectacles) · 1286 ADGlass ground into curved surfaces that bend light to a focus — correcting aging eyes, and, stacked in tubes, revealing worlds too far or too small to see at all.
  7. それを作れるものにした ↓
    Photolithography1957 AD · 1957 ADPrinting with light: project a circuit pattern onto a light-sensitive coating on a silicon wafer, so billions of microscopic transistors can be made in a single exposure.
  8. それを作れるものにした ↓
    Integrated Circuit1959 AD · 1959 ADAn entire circuit — transistors, resistors, wiring — manufactured as one piece on a single sliver of silicon.
  9. それを可能にした ↓
    The Internet1969–1983 AD · 1983 ADA network of networks with no center: any computer can reach any other by passing packets through whoever is in between.
