I wonder about the same thing. When I graduated in 1985 Fortran was already described more or less like you just did. However, when I recently dug down through the NumPy/SciPy stack to understand some details I saw a lot of Fortran code. Some popular algorithms seem to exist only as Fortran with various language interfaces on top.

So I don't think there are very many new projects being started but the presence of so much critical code in Fortran will extend its lifetime some more.
