Can a non-human entity accept an agreement? I know there are things like mountains and rivers which have been granted legal personhood. But obviously they have humans who act on their behalf.

The general question of the personhood of artificial intelligence aside, perhaps the personhood could be granted as an extension of yourself, like power of attorney? (Or we could change the law so it works that way.)

It all sounds a bit weird but I think we're going to have to make up our minds on the subject very soon. (Or perhaps the folks over at Davos have already done us the favour of making up theirs ;)
