Sure. It excels in cases where 60-90% success rate is better than nothing. If you have a smart mine that doesn't detonate on civilians, 50% success is better than 0. It reduces civilian casualties by 50%, which is still awful, but if you're going to plant mines it's better than entirely indiscriminate. Use cases definitely exist. A false positive means it doesn't detonate on one soldier but might on the next — still an effective deterrent. A false negative means it blows up a kid, which a dumb mine would also do anyway.
It's just generally not in situations most people are generally thinking about. You have to imagine cases where there is some upside and no downside. It doesn't work in a context of say, auto-breaking a car if a pedestrian is detected because a false positive is going to cause accidents and probably kill people even if in other circumstances it does save lives.
