Speculation was not inevitable. Seymour Cray’s vector machines demonstrated that speculation was never the only path forward. They rejected it entirely, relying instead on predictable memory stride patterns, explicit vector lengths, and deterministic scheduling. Parallelism was exposed directly to the hardware, not inferred through guesswork, and latency was something to plan around rather than hide.
