Very rarely will a modern gun discharge if it is dropped or mishandled in someway, particularly if you have something like grip safety.
Most "accidental" shootings are negligent discharges caused by user error and I think people are looking for a technological solution to an educational one. Unlike a lot of gun owners I wasn't raised around them and didn't own my first gun until my early 20's but I took a hunting course and a concealed handgun course (note: I never actually applied for a concealed handgun permit but rather just took the class) and learned a lot about handling a gun that I may have never known any other way, things like; trigger discipline, always assuming the gun is loaded, an unloaded gun is not an empty gun and so forth.
There really needs to be more education about safely handling guns but unfortunately it is considered politically incorrect to talk about guns or to teach children to respect them but despite that our culture accepts being entertained by them while being incorrectly handled by actors in every conceivable way. Even the very basics of gun safety like Eddie Eagle which teaches kids not to touch guns and tell an adult has been pulled out of numerous schools because it's politically incorrect.
