COBOL
Batch processing lingua franca of mainframes. Despised in conferences; irreplaceable in unemployment and banking ledgers.
COBOL stuck because rewriting forty years of audited batch logic is a career-limiting migration with no upside. Admiration is near zero; adoption is enforced by law and fear. Every "COBOL crisis" headline ends with paying retirees triple market rate.

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.
