When this applies
when the core demand driver for your product/asset is being disrupted by a new technology
The takeaway
Own the underlying resource/capability rather than just the current application, so you can survive the death of the application and capture whatever application replaces it.
Why it works
Owning the underlying raw-material assets (oil fields) rather than just the specific use-case (kerosene lighting) meant that when a new use-case emerged (automobiles), the existing asset base was automatically repositioned to capture the new demand, without needing to have predicted it.
One level up
Durable advantage often comes from controlling a fundamental asset whose uses can shift, rather than from betting correctly on which specific use will persist.
Where it stops holding
This stops working when the underlying asset itself becomes obsolete (not just its current use), or when the owner lacks the capital/willingness to keep inventing/adapting alongside new technologies.
Detail
situation: Rockefeller's oil empire was built on kerosene for lighting, which was being destroyed by Edison's electric lighting.
decision: Rockefeller's company retained ownership of the oil fields and kept inventing new technologies rather than being purely tied to the kerosene use-case.
outcome: The automobile created a larger and more durable use for oil than kerosene had been, and oil prices rose for decades; Rockefeller's business is arguably the only one from that era 'still standing'.
lesson: You can argue it was partly luck ('God gave them a better business'), but owning the asset base is what let them benefit from that luck instead of being wiped out.
In their words
And they had the possessions of all the big oil fields to ride out. And they kept inventing new technologies. So, whatever value they thought was there, it was really a little more.
