Smart guns are a neat idea on paper. They'll never survive reality

Kloepfer's smart gun works on the basis of a fingerprint reader. Press your dabs against the grip and ping! After a small delay for authentication you can blat away to your heart's content. The reader is set into the grip, so your fingers bear against it as you hold the firearm normally, and is powered by a battery.

Unfortunately, the main obstacle to smart guns is consumer willingness to adopt the technology; without that, all the good intentions and product demonstrations in the world won't get it to take off. Governmental regulation is likely to be ignored and sidestepped, particularly in a country with tens of millions of non-smart guns already in circulation.

As if there aren't enough "smart IoT" devices around already. When you own a gun for self-defense, you want the device to be as simple and reliable as possible so it works even under the worst circumstances. Empty batteries or buggy sensors are simply not an option.
