Where is the human in the loop for typical mine deployments? We already have autonomous killing machines, it's just that they are not very sophisticated, often having trouble to tell children from tanks.
I'd expect that mine manufacturers jump on the A.I. bandwagon to suggest that weapons are designed to be less harmful to civilians, and should not be subject to bans on certain types of mines.
The US already uses self-deactivating mines when deployed (after a couple days or months they go inert on their own). The trouble is like any system the mechanism can fail to deactivate (1 in 100 was an estimate I remember from 10 years ago).
