Part X: The Fortran Future
"The reports of my death are greatly exaggerated." — Mark Twain, a sentiment Fortran has earned
A language that has survived seventy years and is still standardizing new features every few years is not coasting toward retirement — it is evolving. Part X closes the book by looking forward: at the Fortran 2023 standard and the features beyond it, at the surprisingly vigorous community rebuilding the language's tooling in the open, and at the careers that Fortran fluency opens — careers, it turns out, that go begging for lack of people who can do exactly what you can now do.
These two short chapters are the book's exhale. Having taught you the language from Hello, world to
parallel supercomputer code, we step back and place it in time: where it has been, where it is going, and
where you fit into that story. The running project makes its final appearance not as an exercise but as a
portfolio piece — evidence, on your résumé and your GitHub, that you can write real computational science.
What You Will Learn
Chapter 39 — Fortran 2023 and Beyond. The newest standard's features (conditional expressions,
enumerations, typeof, better C interop), how the language evolves through the J3/WG5 committees, and the
fortran-lang renaissance — stdlib, fpm, the playground, and the interactive LFortran compiler.
Chapter 40 — The Fortran Career. Where Fortran programmers actually work — national labs, weather services, aerospace, energy, finance, academia — the roles they fill, the shortage of people who can fill them, and how to present Fortran as the asset it is.
How This Part Fits
Part X assumes the whole book, lightly. Chapter 39 revisits object orientation (Chapter 10) and coarrays (Chapter 32) to show how they are still improving; Chapter 40 asks you to package the solver from the capstone (Chapter 38) as something you can show an employer. Read it as a coda — and as an invitation to go contribute to one of the open scientific codes that keep the world running.

Turn to Chapter 39 for what is new in the language — proof that Fortran is not finished, but still being written.
