That's not really what they meant. They meant that the weapon is guided by software that decides which targets to pick and autonomously makes that decision without a human in the loop. The device seeks you instead of you going to it.
A landmine has no friend-or-foe-or-noncombatant decision engine, it will kill you or maim you just like it will kill or maim the guy that laid it or any other passer by.
You missed the point. The Mk 60 Captor is not a "land" mine. It is guided by software and autonomously makes the decision to launch a homing torpedo without a human in the loop.
