People often sneer at Fortran, but there's a lot that can be done with it in scientific computing, including very performant GPGPU computing. That being said, the dream of having a matlab like prototyping environment directly result in production level HPC code is probably never going to be realised in Fortran - maybe Julia will get there? All I can say is that the tooling needs to be top notch for that to happen and the performance can't just be in the order of magnitude of Fortran/C - it needs to be within 20% or so. Once you run software on clusters that cost millions, programmer time becomes rather cheap, especially in academic settings.
