I hate the idea of smart guns, but politics are a distant secondary concern.
Firearms fail all the time, even the simple reliable ones. Bad primers, failure to eject, failure to cycle, stovepipes, etc. It takes education and then repeated training to know how to deal with failures. In a pressure situation you revert to your lowest level of training; muscle memory will give you the best chance to respond appropriately.
Just dealing with mechanical failures quickly and correctly takes very intentional practice.
The last thing I want to have is another thing that can fail in a pressure situation that can't be resolved via trained response. E.g., for a bad primer or failure to eject I can do what's called a tap/rack/bang drill. But there's nothing I can do to train for some type of software failure or battery being dead or some other type of non-mechanical failure that bricks my firearm.
[1]Former because the NRA"s lobbing efforts and powers are ridiculously overstated. Their entire entire existence as near as I can tell is to sell their member's names to third parties. I've never received as much crap snail mail and email as I did during the year I belonged to the NRA.
