So what, though? "The Intel® Fortran Compiler 2025" just uses the

to perform much the same as anything else using LLVM.
FORTRAN was a dead end, both in syntax
(line-oriented, line
numbers) and
semantics (common blocks, static arrays, very poor string
support).
Fortran 2025, the sixth edition, is rather different from 1956.
The only good reason to use Fortran today is if you
have a large
legacy
codebase in Fortran, or are targetting a platform which is not
supported by
LLVM. Arguably the same applies to C.
I guess that explains why the NASA climate models being developed at
Goddard are all in Fortran, and all of the data analysis codes for many
Earth-observing satellites are developed in Fortran
A bad reason to pick Fortran or C is having been
taught it at school
and
then making no effort to update one's skills at any point in the
intervening
decades.
This assumes that your professors are teaching Fortran 66 instead of
Fortran 2025. I'd be interested to know what you believe its defects to
be.
