Non-developer recruiters who really want to understand technology can learn it. My girlfriend is one, I've got her this book - http://www.amazon.com/gp/product/B004V9HC48/, which her boss since made mandatory for all recruiters in their company.

Of course, that's not enough by itself, and it's a long process, but there are recruiters who do go through all the trouble of learning technology.
