I couldn't agree more in fact I think every individual on this planet has to be aware of cyber security but taking the course is not really necessary for everyone, it will be better if we aware of its basics and striking the right balance between convenience and security.
Advanced security measures may involve longer and more complex processes, which can be cumbersome for everyday use. Even if we are completely educated about all the things involved still no security system is foolproof and human errs can lead to vulnerabilities and further complications.
And your statement be like everyone has to become a doctor because they are at the risk of getting sick anytime, Am I wrong?
Everyone should know about cyber security. Because the present age is the age of technology. The next generation will be completely dependent on technology. If someone loses everything there due to his safety, he will be responsible for it himself. But while some may disagree on whether advanced level cyber security is mandatory for everyone, I would say that it is not mandatory for everyone yet, but they will be required in the next few days. But considering the future, it is necessary to know these things.
