Scientists and engineers still rely on Fortran software for doing their calculations.
Fortran software from decades ago? How does that refute my point of Fortran being used by a few unfortunate bastards maintaining legacy bullshite? Direct interaction of scientists and programming languages probably ends on something like Python, if we are being generous.
LAPACK is written in Fortran and is a dependency of many science and engineering tools.
One library is the best you could manage? Really? Well, what did it meaningfully advance? I believe if it was really meaningful, it is also widespread and significant to many people worldwide, right?
