The goal of abstraction is not to prevent you from knowing what's going on underneath the covers. It's generally to allow you to work on the whole with higher level constructs.
It makes a great deal of sense to understand the complexity you're abstracting away, first. Otherwise, you never really know what you're doing. At the end of the day, you're executing on a computer and you're doing yourself a serious disservice if you're ignoring that fact and hoping either Moore's Law or horizontal scaling are the answer.
