Look at how much time, money, and energy you have for prepping. Assess your risks. Prep for the more likely disasters first. If you have resources left over for prepping for EMP, why not. As for me, I've got a whole list of things that are much more likely to happen, that my budget doesn't permit me to prepare for. For instance, if I get stuck on the toilet seat So I put prepping for EMP in the same bucket as prepping for an alien invasion. Maybe I'll get around to it one day.
