This underscores the problem with generalities. I know of some applications that would be considered high-speed (both literally and figuratively, since they are related to rocket testing) that still rely on FORTRAN. So I think your statement needs some qualifies (what kinds of jobs?)
I guess I should have put quotes around that. It was intended as a specific example of when that decision might make sense; you're using the wrong language for the job because it was the best choice when you started the project decades ago. I didn't mean to suggest that FORTRAN is not the tool for any job.
