I love it.  Just about every year, one of my Computer Science students comes to me rather sheepishly and admits they have changed their major.  I had one that is in his sophomore year that just came to me and told me that he switched from Chemical Engineering to CS.

Not that there is anything wrong with Chemical Engineering, but he groked CS so well.

Makes me happy.

And I question the dark side part – as it really is a good way to make a living, but not sure how to describe it otherwise….
