C
The substrate language. Kernels, compilers, embedded — still the lingua franca when you need the metal.
C won because it maps cleanly to hardware and compiles everywhere without ceremony. Every "safer" successor still talks to C at the boundary. It stuck not from hype but from being the lowest common denominator that actually ships.

Context
Machines learn to share a language
This era built the substrate. Process models, pipes, files-as-interfaces, and relational algebra were not fashion — they were constraints that happened to scale. C and Unix made portability a real goal; SQL made data queryable without rewriting the world. Later decades mostly decorate or redistribute these ideas. When something from this era still looks “boring,” that usually means it won.
