The ultimate goal of Information Technology is to reach the highest level of abstraction possible. If this goal is ever achieved, then it won't just be SQL we won't need to worry about, it'll also be Perl.

Then no-one will be able to understand how anything works. Layer upon layer of abstraction usually decreases efficiency and increases the number of different places you have to look to understand how something works. There is a law of diminishing returns at work and beyond a certain point you end-up with Java lego code, which is how many new students now enter the software industry. I got into Perl after rejecting this facet of Java but Perl can end-up the same if you keep adding more and more layers of abstraction.
