The thing is, we’ve had unstoppable, zombie-like, intelligent actors capable of taking out a single human for at least a century. They have legal status, can own property, can file lawsuits, own weapons, have security forces, and they self-replicate based on available resources.
They’re called “corporations”.
I remember watching Bicentennial Man, and the part where the rights of the robot was under question in the movie struck me.
Reading this, I wondered if it was possible to build a robot, and to give it rights under the present legal system, simply create a corporation assigned to the robot?
