"The good news about computers is that they do what you tell them to do. The bad news is that they do what you tell them to do"
About this Quote
The subtext is an early, sharp warning about automation’s literalism. Computers don’t “understand” intent; they enact instructions with a kind of weaponized sincerity. That creates a specific modern dread: not that machines will rebel, but that they’ll comply. Bugs, security holes, biased models, catastrophic scaling errors - these aren’t betrayals. They’re the bill coming due for ambiguous specs, sloppy assumptions, and incentives that reward shipping over sense-making.
Context matters: Nelson is a pioneer of hypertext, a figure who spent decades arguing that the way we structure information shapes how we think and how power flows. So the quote isn’t merely programmer humor; it’s a critique of bureaucratic thinking translated into code. “Do what you tell them” is also how institutions behave when rules become the substitute for judgment.
It still reads like a diagnosis of our AI era: the danger isn’t malicious sentience, it’s high-speed literalism at scale. The line dares us to stop anthropomorphizing machines and start interrogating ourselves - our instructions, our priorities, and our refusal to own the consequences of our own commands.
