In Defense of C++

C++ will always stay relevant. Software has eaten the world. That transition is almost complete now. The languages that were around when it happened will stay deeply embedded in our fundamental tech stacks for another couple decades at least, if not centuries. And C and C++ are the lion's share of that.

COBOL sticks around 66 years after its first release. Fortran is 68 years old and is still enormously relevant. Much, much more software was written in newer languages and has become so complex that replacements have become practically impossible (Fuchsia hasn't replaces Linux in Google products, wayland isn't ready to replace X11 etc)

As long as people write software (no pun intended), software will follow trends. For instance, in many scientific ecosystems, Matlab was successfully replaced by Scipy. Which happens to get replaced by Julia. Things don't neccessarily have to stay the same. Interestingly, such a generational trend currently happens with Rust, despite there has been numerous other popular languages such as D or Zig which didn't have the same traction.

Sure, there are still Fortran codes. But I can hardly imagine that Fortran still plays a big role in another 68 years from now on.

You’re thinking of software that is being written today. GP is talking about software we use every day in every device on the planet that hasn’t changed since it was written 30+ years ago.
