The more I read about Fortran the more fascinated I become with it. Its treatment of arrays is similar to Pandas/Numpy. The performance is close to C without any optimizations. Without the pointer laden complexity and gotchas that come with C/C++.
In my opinion, Julia is a good successor of Fortran. In my opinion it behaves as a child of Python/Numpy and Fortran ;-)
I took a coin flip in grad school to decide whether to focus on Python and Fortran. Python won the flip, but I've always loved Fortran generally.
