Toddlers, children and teenagers and people suicidally depressed do it all the time. That’s why doctors ask about guns in the home.
I wonder if the police would find this useful when apprehending violently dangerous gun toting criminals.
If it is online-accessible or requires to plug it into your connected system for support/maintenance/update… you may wind up with an unsolicited U2 album on it 
Which pretty much means your owner-ID modules would have to rely on something that is not accessible/spoofable via RF from any distance other than essentially on you.
This would have the issue that if they use a general ranged jammer, thet’d be likely to interfere with their own smartguns. And makers would want the individual units to be “keyed” either uniquely or to a very small number of possible ID modules.
At least you would have an immediate remedy at hand to avoid having to be subjected to it.
You probably need to rethink this as it happens all the time. And I’m not talking about once a week. How many kids are shot by, or shoot themselves with, a parents gun? How about suicides using a parent or partners gun? Not rare and especially not very rare.
As for digital locks on guns, I think a big no. Too complicated a answer for the problem they would solve. I would rather have more responsibility put on gun owners to secure their weapons. It’s you weapon, you are responsible for it. If the gun is out of your personal control, secure it with a gun lock or better yet a safe. Your kid gets your gun and shoots themselves or someone else? You go to jail. You pay all damages. You don’t get to own guns again, since you have proven you are irresponsible with them. It’s your weapon, you are totally responsible for it, step up and take that responsibility instead of blaming everyone else.
