Think of it this way: mines installed in the seabed in wars past were "dumb", in that a passing ship had to happen into it. Imagine systems deployed underwater that were mobile, contained multiple torpedoes, and could strike warships with little to no warning given their small acoustic signature. It's the same principal as a mine (you leave it one spot, hope an enemy ship comes by), but the capabilities are far more advanced. If the system is not at least semi-autonomous than it might as well be a dumb mine again.

In an existential conflict no one cares about human rights. That's something for the winners to worry about after the shooting stops.
Modern tools lend themselves more to information warfare and deobfuscation.
