20-Year Prospect
One thing that the world will need twenty years from now is CEOs to run companies. Can you imagine a classroom without a teacher, with you and your classmates deciding what to learn that day? It'd be great, right? Until it came time for final exams, when the unanimous decision to spend the semester choreographing and filming lip-sync battles may end up seeming like a waste of time (kidding, that's never a waste of time).
The same goes for businesses. Someone has to have the vision and give the directions for the rest of the company to follow. The only thing that will change is how a CEO can remain effective as the business climate changes.
Technology continuously changes the expectations for free enterprise leaders—consider the ways social media creates a new necessary skillset for a CEO, for example. On the bright side, maybe that semester making lip-sync videos wasn't wasted time after all.
Oh, and let's not forget chicken. Chicken passed beef as the number one meat more than twenty years ago and continues to lead (source). In fact, per-capita consumption of chicken is nearly equal to beef and pork combined.
So yeah, both your job and industry seem to be pretty secure.
