Assembly
The metal under every abstraction. You do not write it for CRUD; you write it when cycles, size, or boot ROM matter.
Assembly stuck at the bottom of the stack because someone still writes kernels, firmware, and hot loops. It failed as a product language when compilers got good enough. The costly fad was hand-tuning everything while the business needed shipping.
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.

C
The substrate language. Kernels, compilers, embedded — still the lingua franca when you need the metal.

Fortran
Formula Translation for scientists who needed numbers before "software engineering" was a job title. Still runs the weather, the bomb labs, and half of HPC.

Unix / POSIX
Process model, pipes, and files-as-interfaces. Linux and macOS still speak this dialect every day.
