Theremay be bad (or at least inefficient) languages, but there are lots of bad programmers.

Therewill no longer be a need for it. This will make the SQL language simpler and easier to use, understand, and reason
about.
I think you ought to recognize that many people on this list make
money directly from managing that complexity :-).
Processing time remains bounded, and for complex queries how much time
is spend executing vs planning is a very difficult tradeoff. Just
like in math, there are many ways to describe the same thing, and it
is for the clever to pick the best ones that run efficiently and well.
And thank goodness for that; it sends my kids to college.
Relating to your other point relating to implementations, it's not
different than having different browsers that render html and execute
javascript. Having several high quality implementations to choose
from is healthy and good, and allows choice best on cost and feature
needs. I would personally be much more inclined to gripe about
implementations that do not support standard syntax or have other
major standards issues (SQL server, I'm looking at you).
