In a market where people commonly remove magazine safeties from their pistols to improve the triggers, decry electronic sights because batteries are too unreliable, choose to buy guns without manual safeties because of their simplicity of operation, and rail against, or even completely refuse to buy, guns with mechanical locks, the idea that electronically controlled firearms are going to catch on is anything but smart.
The bottom line is that most people will only buy "smart" guns if they are forced to do so. Which is probably fine with many of the people who claim that "smart" guns are a good idea since it appears that their primary goal is forcing gun owners to comply with their wishes, not making guns safer or smarter.
