TCP/IP
The network stack that won. Every "revolutionary" protocol still rides these packets.
TCP/IP won by being good enough, debuggable, and incrementally deployable — not by committee perfection. Alternatives arrived with better slides and worse adoption paths. The internet is the proof that boring protocols outlive elegant ones.

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.
