Surprisingly dramatic & awesome.
As much as it is a grand idea, it's giving an opportunity for people who are already lax on personal responsibility to be lax further. I offer the same argument against "effiency" software that disables internet access or blocks certain websites during "working hours." Grow some discipline and self-control already!
Very interesting concept, and I understand its intended purpose of cutting down on unnecessary deaths. However, I feel that the real issue here is people not adhering to proper gun safety, mainly keeping them out of a child's reach. And while the safety features are nice, a child should not have access to the gun regardless. I fear that the extensive safety features may cause an even larger lack of safety regarding firearms. This technology is very cool though and I find the fact that we even have a "smart gun" fascinating.
