I think we're mostly in agreement about this.  I find that most of the data
processing I do, including conditionals and such, can be vectorized just fine,
although you're correct in saying that some things just don't vectorize.

I think there's comfort in doing the low-level details yourself.  I'm guilty of
this, and only just figuring out that most of what I spend my time doing has
already been done pretty well in a high-level language.

True, although in my experience, most people don't.  The first language I ever
learned was actually the POV-Ray SDL, and it really stuck with me to do all of
the low-level details yourself, relying only on some basic functions.  It works
pretty well for POV-Ray scenes since most don't involve heavy processing, but
sooner or later you start to run into problems.  It's the classic, "If all you
have is a hammer..." scenario.
