What the electronic companies are selling is not so much safety, as instant empowerment. You don't have to take months of courses followed by years of going out with others. Just buy a gps, a chart plotter and radar! And if you still mess up you can call for help with epirb and your dsc radio.
When you are taking your courses and learning from others over a period of time, you are also acquiring wisdom, and learning the unwritten code of behavior called courtesy and honor.
If you can't be bothered to take the time to learn the law & lore of the sea...stay home, buy a video game.
