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.，这一点在新收录的资料中也有详细论述
Now, you can get an autonomous dirt-sucker with serious cleaning chops for $500 — sometimes even $300 or less. But you get what you pay for in this space; don’t expect affordable robot vacuum cleaners to have all of the bells and whistles that premium machines do, like self-emptying capabilities or advanced dirt detection. After testing dozens of robot vacuums at various price points, I’ve narrowed down our top picks for the best budget robot vacuums you can buy right now.
