When people tell me robots cannot be copyright holders of works they created because robots are not persons, I just notice that the rivers became legal persons in India. Rivers! That's right, rivers can have rights.
And it's ok.
Law is just an instrument to make the world a better place. We can imagine and establish any legal institutes we want. So if it is useful to grant rivers, robots or even spoons with rights, we can just do it.
@posrev "Not all laws are right" - unfortunately, that's right.
"Giving legal rights to rivers similar to humans is ridiculous" - why? Even non-existent entities that live on paper (I mean legal entities and states), have rights. And it works. I think it works because the very rights don't exist. We build our world on imagination! So I don't understand why now people are so concerned about the nature of robots. That is what actually ridiculous! :)
