Bash is great generally because Bash devs write for a stable target and don't concentrate on using the latest and greatest bleeding edge features. So you can expect a bash script written today to run on a distro from 15 years ago. This is something few other programming languages have achieved (except perl). With python or rust or whatever a compiler/toolchain basically only lasts 3 months because some new feature is added and used that makes your rustc compiler from 4 months ago unable to compile it. Or with python you pretty much have to assume you system python won't work and install an entirely new toolchain using a dependency manager manager to manage your containerization and then within that (venv, pyenv, conda, etc, etc) a dependency manager (pip, PyPI, etc) to actually get the lib versions you need. Only then can you start trying to actually execute the program. Bash? Just chmod +x and run the script. It'll work no matter where you're running it. And it won't stop working.
