I have, I think, a different view: there is too much CS and not enough engineering in IT. The numerous CS grads have a bag of hammers as their toolset and so every engineering problem is a DS&A "nail." At least, here in the valley it seems that way. Outside of it there is at least in my experience much more of a nod toward software development as an engineering endeavor rather than as an exercise in pure CS.
Yes, the theoretic / scientific part does not percolate enough into the engineering practice. Thus the practice is starving without a good conceptual view, while CS may be lacking in engineering department and thus practicality.
