But you don't need computer science to get and perform very well in a programming job. I'm a sample size of one, but I never had any formal comp-sci education and only after about a decade in the industry did I go back and teach myself algorithms, data structures, and all the other comp-sci stuff. I only did this out of interest, not necessity. My experience is not unique.
Likewise... I do find that understanding some of the fundamentals helps, but isn't key to most of the work I do by far... brute force of faster computers and loads of memory goes a long way for line of business applications, which is most of software development (what most work on, not most-used).
