I mean, I'm playing with offline AI right now and reproducibility sucks. Most of this is python based. I think I need to switch to Nix for this situation where I need to compile most tools from source. While python itself my be easily available for previous versions, sorting out the required dependencies is outside of what most users are capable of reproducing. I get the impression C is more centralized with less potential to cause problems. At least when it comes to hobbyist embedded projects, the stuff centered around C has staying power long term. The toolchains are easy to reproduce. Most python stuff is more trouble to reproduce than it is worth after it is a few years old. IMO it feels something like the Android SDK where obsolescence is part of the design. I shouldn't need to track down all the previous package versions just to reproduce software. It should simply work by default when all of the dependencies are named. There should be something like a central library of deprecated packages that guarantees reproducibility. Even if these packages are available somewhere in the aether, piecing together relevant documentation for them is nearly impossible to sort out in historical context. This has been my experience as an intermediate user and hobbyist.
