How did The tractor lead to Large Language Models?

9 steps · 7 domains · 128 years

  1. The tractor1892 (Froelich's gasoline tractor) · 1892 ADA gasoline engine mounted on a self-propelled wheeled chassis with forward and reverse gears, able both to pull an implement across a field and to belt its power to a stationary machine — doing a steam traction engine's work without the coal, the boiler, and the water it had to drag along.
  2. 有赖于它的是—— 使之可能 ↑

    The whole point of the tractor was to swap the steam traction engine's boiler for a compact liquid-fueled engine that started cold and ran on a tankful of fuel; without the internal combustion engine there is nothing to mount on the chassis.

    Internal combustion engine1876 (Otto four-stroke) · 1876 ADAn engine that burns fuel inside the cylinder itself, so the expanding combustion gases push directly on the piston. Nikolaus Otto's four-stroke cycle — intake, compression, power, exhaust — made it practical.
  3. 有赖于它的是—— 使之可能 ↑

    Otto's own engine ran on coal gas; refined liquid fuels — petrol, then diesel — made the engine portable enough for vehicles.

    Petroleum refining1855 (Silliman's report); first commercial well 1859 · 1855 ADBoiling crude oil apart into fractions by temperature — light naphtha and gasoline, then kerosene, then heavy oils and tar — turning a black, useless seep into lamp fuel, lubricants, and eventually the fuel of the modern world.
  4. 有赖于它的是—— 使之可造 ↑

    Refining is distillation applied to crude oil — the same boil-and-condense separation, scaled from the alchemist's still to the fractionating tower.

    Distillation~800 AD (alembic systematized in the Islamic world) · 800 ADBoiling a mixture and catching the vapor, so that the parts that boil easiest come off first and condense back to a purer liquid. Separation by temperature — it makes nothing new, it only sorts.
  5. 有赖于它的是—— 使之可能 ↑

    Clear glass lets the distiller watch the boil and condensation and resists the acids and hot vapors that corrode metal and clay.

    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. 使之可能 ↓
    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. 使之可造 ↓
    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. 使之可造 ↓
    Integrated Circuit1959 AD · 1959 ADAn entire circuit — transistors, resistors, wiring — manufactured as one piece on a single sliver of silicon.
  9. 使之可能 ↓
    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.
  10. 使之可能 ↓

    The training corpus IS the internet; no other artifact contains enough recorded human language.

    Large Language Models2018–2022 AD · 2020 ADNeural networks trained on internet-scale text to predict the next word — and which, at sufficient scale, turn out to translate, code, reason, and converse without being taught any of those skills directly.
