CODASYL's COBOL (1959) — designed by committee in six months — made business computing English-readable: ADD, COMPUTE, PERFORM. Grace Hopper's FLOW-MATIC was its closest ancestor.\n\nIt is still the largest deployed codebase on Earth — an estimated hundreds of billions of lines in production — and 65+ years later Y2K-era fears about its maintainers' retirement remain current.
