The absolute primary function of a gun, the reason it’s owned, is for it to go BANG in a life-and-death situation.
The #1 failure mode users most want to avoid is “pull trigger, no bang”.
That’s the whole purpose of this tech: cause exactly that to happen.
If this tech fails, as in a legit user tries to fire in defense of innocent life, it won’t.
The CORRECT failure mode is to fire on demand, even if the user isn’t authenticated.
Their failure mode is, and I predict, an expensive paperweight.
I worked at a bank some time ago. Part of my job was installing and repairing the millions of locks there. The locks were set to “fail/open” ... if the power went out all the doors and vaults would automatically open so as not to trap people. I suspect these smart guns will also be set to misfire under many circumstances; i.e. within 500 yards of a school.
