Just because you decided to call it a "tool" (rather than for example a really powerful optimization process) and would prefer to think of it as a tool does not constrain what it might do. It's going to do what it is going to do regardless of what word you use to describe it. I'd rather not stake my life on the argument that "well, it's fair to call it a tool, and so far in history nothing called a tool has ever tried to cause human extinction."
