In reality,the technology will happen incrementally, problems will be experienced, predicted and solved as they happen. Autonomous machinery isn't going to happen all at once. Here's Asmov's three laws:
A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.[1]
