Crazy ridiculous safety saw can detect fingers and shut off

I’m in awe of this SawStop safety saw. Basically, it has a fancy capacitance sensor in it, that can detect when the blade makes the slightest contact with a finger, and immediately stop it’s rotation and pull the blade out of reach. The standard safety arguments (potentially great benefit, but adds cost, complexity, possible complacency) probably apply here, but it sounds like a great idea- does anyone here have experience with them?
