Do you see the circularity in your reasoning? A machine can't be held responsible because it's not a legal person..and it's not a legal person because it can't be held responsible.

You also claim that some legal persons are persons simply because society benefits from allowing groups of persons to act as one. If this is the threshold for personhood - society benefits - then I am confused why this threshold would not also extend personhood to machines.

I guess I'm looking for a clear bright line for defining personhood that includes humans, rivers, and corporations while excluding machines, and I'm not seeing it.
