> because it's impossible to improve a programming language

Well, since "improve" is a relative and a matter of taste, it is impossible to improve a language, isn't it? Make it run faster, and it will either take up more memory or be slower to develop with. Make it faster to develop with, and it will run slower or have some other tradeoff.

Hence, "use the right tool for the job". And when your focus shifts from "quickly building a product" or "quickly adding new features" to "rock-solid stable and fast", then you need to switch tools. Simple as that.

Could you please tell me what fortran is the good tool for ? :)

As much as I agree it's delusional to think one language may be adapted for virtually any kind of tasks, it seems way too much consensual to me to tell there is no such thing as bad or deprecated languages.

Fortan is great for FEM. Companies like Siemens are using millions of LOC of Fortran to virtually crash cars and explode bombs.

Also, Nastran got us to the moon (which is basically Fortran)
