I couldn't tell if that was a moron rant or a trolling article. Sounded like a trolling article.
I was surprised that the article did not mention biometrics. That seems like the only tech that is possibly within reach that would make guns "safer". If your gun would fire only for you, or for others that you allow to use it, that could prevent some of the tragedies we've seen. The hardware and software for such things already exist, but integrating them into a firearm is a serious engineering challenge. It would have to be reliable, fast, and at least somewhat tamper-proof, and more importantly something that people would be willing to use. I don't see even this (relatively speaking) simpler technology happening anytime soon.
