from an article in Slate Magazine:

“Asimov’s faith in the rule of robots was genuine and based on his faith in the rule of reason. He viewed his now-canonical Rules of Robotics—the code for robot behavior used in his books—as a roadmap for human ethics. Just as Asimov’s machines are better than people at calculating mathematics, they’re superior at coming to moral judgments as well. Susan Calvin, the book’s protagonist, calls robots a “cleaner better breed” than humans because they’re “essentially decent.” Superior logic produces superior ethics.

“The movie takes the exact opposite approach and thereby betrays Asimov’s vision. It elevates feeling and emotion over reason as a tool to determine the right moral decisions. Will Smith’s character, Del Spooner, sneers at robots as “slaves to logic.” When another character pleads, “Whatever you feel, just think,” the audience is meant to take his preference for reason over sentiment as a sign of his villainy. And when the main antagonist outlines the Dastardly Plan unveiled during the film’s climax, the villain defends the treachery by asserting, ‘My logic is undeniable.’”

Many people said I should see the movie. “It’s not what you think it’s about,” they told me. “It’s very faithful to Asimov’s ideas, if not the book.”

My reply: “Have you read Asimov?”

Their answer: “No.”

Me: “Then you have no idea what you’re talking about.”
