Awesome post. Let me add one thing, though: If you like BASIC, you will love FORTRAN. It is procedural, so it is similar in concepts to BASIC; and it is extensible, so you can start with a Hello World program in Fortran with a PRINT *, "Hello World", similar to BASIC's PRINT "Hello World".

You can then gradually introduce concepts, such as loops and conditionals in the same way with BASIC; then, you can take on more complex ideas, such as variable typing and allocation (IMPLICIT NONE ftw!), pointers, modules/classes, and you can go all the way to object oriented fluff with the latest standards.

Moreover, FORTRAN is still being used in industry, and not just as a legacy language. There is extensive development of parallel code in Fortran, and the language still reigns king in High-Performance Computing. Thus, the language can grow and be anything from a crayon to a calligraphy quill as desired.

At that point, you're fucked...

And we have a winner!

Most people do not want to write their eigensolvers, Poisson system solvers, matrix multiplication routines, and the like. They just want to use code that already does that, and that has been tested to do its job well. Code verification is important. So, the libraries that do so need to be ported before anyone in HPC switches to GPU architectures seriously. (Remember: this is the land where FORTRAN is still king...)
