Still a good number of packages you are using right now on your Linux distribution have a core more than 15-20 years old and still they compile only with minor modifications with the last GCC. Compatibility does matter. It should however not prevent evolution. If handle properly, nothing block us to get a proper versioning and evolution path on the toolchain we use. And on many aspect C++ up to now has been very successful to do that. > You can't actually run code from 80's out of the box today Good C is close to immortal. Doom is from 93, and still you can compile it and run it with the last compiler in 2020 with minor modifications.
