Recently I came across this post in LinkedIn and it is interesting that they show how NumPy leverages Fortran code for compute-intensive kernels like MATMUL:
I did not find the link to the technical article yet. I will post it here!
Are you aware of other evidence of Fortran powering the GenAI tools?
