>As humankind spread throughout the known universe, technology advanced and eventually machines were made that would make decisions for people. This propelled the creators of these machines into a new technocratic class, effectively controlling the worlds of the common people.

It's right there in the opening paragraph of OPs post. It's the people who controlled the machines that could not be trusted. We're not worried so much about about AI going rogue. We're worried because people who control it have aleady gone rogue. It is too powerful and dangerous a tool to be trusted in the hands of primates.
