After discovery of principles according to which the Universe runs(the process continues) the next logical step was to use them to make human life more comfortable, safety is also part of that. All these inventions have caused loss of human life and will regrettably continue to do so. It is perhaps the price of those comforts. Medicines that are discovered to save lives have taken lives, get banned and newer safer ones are discovered. Aviation is no exception to this. Car brakes fail you don't switch to horses but make better brakes. It is perfectly reasonable to expect better safety from the gadgets but can one be paranoid about them?
