Creating the human standard for ethical autonomous and intelligent systems (A/IS)

Like most people, I first encountered Artificial Intelligence through movies - The Terminator, Blade Runner, 2001. As a rule, the future in these stories was always dystopian which I found irritating. If humanity was able to create such amazing technology, wouldn't they also have created ethical codes or standards to keep things from going awry? Granted, a film about a code of ethics isn't as sexy as killer robots, but picturing utopian futures powered or assisted by AI seemed like something not enough people were doing in my estimation.
