While it is categorized there, most IS grads aren't qualified to work in Silicon Valley company engineering departments, or even in most engineering/software dev. departments of non-SV companies. To use IS grad unemployment rates in this argument is arguing semantics.
It does qualify for STEM, but the fact is that "Information Science" people don't know how to write code.
Silicon Valley needs people who can code, not people with "5+ years of experience using MS Word"
Not true again. My masters is in Information Science, I have written code for a long time.
