Digitally targetted firearms NOV 28 2012
A company called TrackingPoint is developing guns equipped with digital scopes that enable automated precision firing. Here's how it works: you "tag" a target with the digital scope and then only when the gun is aimed directly at the target, it fires. Essentially, it lets you practice pulling the trigger any number of times before the gun actually shoots the target perfectly for you.
I'm alternating between being really impressed by this and really freaked out by the implications. That's technology, I guess. (via @jomc)
