"It's hardware that makes a machine fast. It's software that makes a fast machine slow"
About this Quote
The specific intent is less “software is bad” than “software is where complexity hides.” Hardware improves along relatively legible lines: faster chips, better buses, broader bandwidth. Software, by contrast, accumulates. Features stack. Dependencies multiply. Abstractions pile up until the machine is spending cycles on bookkeeping, telemetry, UI gloss, and compatibility promises instead of the job you thought you bought it for. That’s the subtext: progress doesn’t just add capability; it adds overhead, and overhead is political. Someone, somewhere, decided the extra layer was worth it.
Context matters: Bruce is writing from the late-20th-century onward, when Moore’s Law made performance cheap and the software industry learned it could trade efficiency for speed-to-market, richer interfaces, and relentless updates. The joke is also an accusation: “fast” isn’t a property of the device alone, it’s an outcome of discipline. Hardware can be purchased. Restraint has to be engineered.
