What existed / what was created · what was killed / what was spawned · the principle functional schematic (the abstraction)
Three new cross-sections layered over the full value chains: (A) upstream markets — what existed before vs. what was created; (B) downstream — at finer grain + new/transformed/killed/spawned; (C) the principle functional schematic (the ladder of abstraction).
| Supplier industry | Status | Comment |
|---|---|---|
| Coal mining | ⚪ existed → reconfigured | already existed (heating, rail, metallurgy); power generation became a large NEW customer |
| Copper mining | ⚪ existed → reconfigured | already existed; electricity doubled demand (~½ of all copper) and added a refining process |
| Steel (structural) | ⚪ existed → reconfigured | already existed; towers/casings — a new demand segment |
| Porcelain/ceramics | ⚪ existed → reconfigured | existed (tableware/sanitary ware); HV insulators — a new product |
| Rubber | ⚪ existed → reconfigured | existed; cable insulation — new demand |
| Machinery/metalworking | ⚪ existed → reconfigured | existed; turbine-building — a new branch |
| Rail and logistics | ⚪ existed → reconfigured | existed; coal for power stations — the largest freight |
| Banking capital | ⚪ existed → reconfigured | existed; utilities/holding companies — a new asset class |
| Electrical equipment manufacturing (GE/WH) | 🔴 CREATED | no such industry existed — it was born for electricity |
| Electrolytic copper refining | 🔴 CREATED (process) | a new processing stage that emerged from electricity |
| Silicon electrical steel | 🔴 CREATED (product) | a new material-product within the steel industry |
| Bakelite / plastics | 🔴 CREATED | born of the need for insulation → a separate industry |
| Varnish/enamel for magnet wire | 🔴 CREATED | a new material for winding wire |
| Meters/instrumentation, grid construction | 🔴 CREATED | measurement/metering + grid construction — new industries |
| Electrical engineering (talent) | 🔴 CREATED | a new profession/education/unions (IBEW 1891) |
| Technology node | Market | New / Transformed | What it KILLED / displaced | What it SPAWNED (cascade) |
|---|---|---|---|---|
| Lamp | Lighting | 🟢 transformed (gas→electric) | gaslight (migrated to heating/cooking), candles, kerosene, whale oil, lamplighters | night economy, evening retail, the lit city/factory |
| Electric motor (unit drive) | Manufacturing/factories | 🟢 transformed (steam/water→electric) | the steam engine in the shop, the line shaft, the water wheel | factory replanning, productivity growth (lag 20–40 years), electrified machine tools |
| Traction motor | Urban transit | 🟢 transformed | horsecar, cable car | — |
| ↳ (same) | Suburbs/real estate | 🔴 NEW | — | streetcar suburbs, land-value capture, interurban |
| Elevator + pump (secondary, on the motor) | Skyscrapers/vertical real estate | 🔴 NEW | the low-rise ceiling (~5 floors without an elevator) | the dense city, vertical rent, a new asset class |
| Electrolysis | Aluminum | 🔴 NEW (the industry did not exist) | — (aluminum was semi-precious) | aviation/transport/packaging later; "frozen electricity" |
| ↳ | Chlor-alkali | 🔴 NEW | old chemistry (Leblanc) | the base of the chemical industry |
| ↳ | Carbide/carborundum/graphite | 🔴 NEW | — | abrasives, acetylene |
| Electric arc | Specialty steels/ferroalloys | 🟢 transformed | — | high-quality metallurgy |
| Refrigeration compressor (secondary) | Refrigerator/household | 🔴 NEW | the icebox | — |
| ↳ | Cold chain/food industry | 🔴 NEW | ice harvesting (the 9th-largest U.S. industry) | national food distribution, meatpacking at scale |
| ↳ | Supermarket | 🔴 NEW format | the corner store (partly) | self-service (Piggly Wiggly 1916) |
| ↳ (air conditioner) | AC → Sun Belt | 🔴 NEW (geography!) | — | settlement/manufacturing across the U.S. South |
| Triode/vacuum tube | Long-distance telephony | 🟢 transformed | — (it amplified) | transcontinental communication |
| ↳ | Radio broadcasting | 🔴 NEW | — | media/advertising/mass culture |
| ↳ | Electronics | 🔴 NEW | — | the path to semiconductors/computers |
| Household appliances | Home/household (durables) | 🔴 NEW | part of manual labor/domestic service | consumer credit for appliances |
Behind the concrete nodes sits a ladder of abstraction. Electricity is a phenomenon; it provides a set of primary functions (by physical nature); from these, devices are assembled; from devices, composites; then applications and industries. This is an "ontology of what the technology CAN DO."
AI is likewise a phenomenon with a set of primary functions; the value lies not in the function but in the composite.
Strategic takeaway: do not sell the "primary function" (the model = the motor — that is a commodity); assemble the composite "elevator" (the way a refrigerator is built from a motor + a cycle) that removes a limit / creates an environment in a specific industry — and own it. The question for every industry: "where is the elevator here that lifts the height ceiling?"
