Bullshit. Most people doesn't know a shit about electronics and they are surrounded with electronic equipment. And this is an example, there are a lot of things I don't know almost anything about them and I can successfully operate with them.
How many people die every year for not understanding the basics of electricity?
Evidently if you try to repair your TV (without knowing how to repair it), change the electrical installation of your house (without knowing anything), touching a high intensity cable or something like that it is a dead by accident or by stupidity.
