My two pence worth, my experience is across python, C++ and fortran (and a few other languages) and the posts here are interesting and relevant. I think that the true value of any of these languages is knowing any of them well, if you happen to work with other folks who share the same skills more the better. No more than that.

As a user of a very old large very fortran codebase as well as engineer of more structured approaches, I would take the OO toolset everytime, for reasons already covered.

The real challenge I see every day in scientific community is the lack of software craftmanship skills, code archiving, unit testing. End of two pence.

I think the main point being made by most here though is that *in 
combination with Python*, Fortran can be quite helpful. If one is using 
Python anyway for the high-level stuff, the relative strengths of C++ 
w.r.t. Fortran that you list become much less important. Same for 
code-reuse: When only used from a Python wrapper, the Fortran code can 
become so simplistic that it also becomes reusable.
