What’s the logic behind having plans for taking down an evil version of yourself? Who watches for that to carry out the plan when the time comes? What’s the plan if that person becomes evil and now has the means to combat non-evil Batman? Does he have a plan for that too? Because if so, evil Batman will also have it.
I understand the concern, but I don’t think you’re asking the right question. I would consider goldfish to be sentient, but I’m not afraid of goldfishes. I don’t consider the giant robotic arms used in manufacturing to be sentient, yet I wouldn’t feel safe going anywhere near them while they’re powered on. What you should be concerned about is alignment, which is the term used to describe how closely the AI agent’s goals match up with that of humans. And also other humans, because even if the AI has the same goals, you still want to make sure that the humans they’re aligned with aren’t malevolent.
It’s possible that someone out there is trying to do it, but in academic settings, if you even hint at sentience, you’re going to get laughed out of the room.
