I do not think that EMP would be something like end of days, but I agree that lot of people will die. Lot of people will have great problems in dealing with new reality, it would be different maybe 30 years ago, but today too many people simply can not care about themselves without help of modern society around them.

There are exceptions of course, i know some people who are living in rural settings, and if something like EMP happens, that is not going to be too much tr4ouble for them, they still know old way of living, they still have skills, or remember skills that they older ones used 30 or 40 years ago.
They would just continue to live, little bit harder, but still they would survive easily.
