Computer Science job security

Which aspects of computer science are profitable and worthwhile? Help a high schooler going off to college...
Hello,
Playing with Windows, applications, and tweaks has always been my passion since elementary school. This past year, I started gaining a beginner's proficiency in Java. Though I am not crazily in love with programming, I do think it is neat.

I would like to study computer science next year. I was accepted to UC Berkeley (College of Letters and Sciences) and Penn State University (Schreyer Honors College).

In our day, where so much code-writing is outsourced almost like "manual labor, " is learning to program still worthwhile? While I am solving my little Java recursion puzzles, I just feel like I am so far away from doing any "useful" programming.

The job climate scares me. For some reason, I've got it in my head that a pre-med student has a guaranteed source of income, whereas a B.S. in computer science isn't as much of a sure thing.
