Should I change my major to CS?

I'm currently a senior in an Art History program at a private university in the US. I love art and studying it, but there seem to be very few jobs available. Should I change my major to computer science to keep up with the supply and demand of the job market?

there are backdoors in openbsd open source code. there are backdoors everywhere. nobody can read millions of lines of code, let alone understand them. there are hardware backdoors, too. not that it matters.
