> those machines that used to be brutally efficient at doing what you asked of them. In a way, that's a natural thing to happen. Computer systems are weird in that we have an extremely good model of how they work at a certain level: "processor will (almost) always process assembly exactly as it should, etc." When computers first came around, this "computer does exactly as you say" thing was weird to people because there weren't really any such things before computers. People would make small mistakes in their code and wonder why the computer can't "just do the obvious correct thing like any sensible person". However, as multiple complex software systems interact and build on top of each other, this ability to "understand everything" at one of these "perfect model" levels (e.g assembly, logic gates, state machines...) becomes useless. To work with them, fuzzy models (like those we use for other humans or animals) are more appropriate. Complex software systems will routinely not do the same thing when given the same command. They will change over time, break in incomprehensible und unpredictable ways, and, as the newest addition, argue with you instead of doing what you say. That development makes total sense. At least those systems can now "take a hint".
