Several things surprised me, both in the blog post and the other comments. (Though hpcjoe's and enriquot's comments took care of the "What? Fortran is dead?" reaction.)

- (Comment) "array operations, ... are slower than explicit loops" May be related to the following:

- No mention of vectors.

- No mention of LINPACK, LAPACK, etc.

- No mention of GPUs.

Fortran arrays are indexed as you choose.

Vectors would be arrays. Array operations will lose if the compiler doesn't scalarization/deforestation properly (if deforestation is an appropriate word when dealing with arrays rather than lists/trees). Subroutines libraries and GPUs are irrelevant.
