alt Hacker News> This is something I generally believe, but I think it's particularly important for things like languages and runtimes: the idea of installing things "on" the OS or the system needs to die.
Python has been trying to kill it for years; or at least, the Linux distros have been seeking Python's help in killing it on Linux for years. https://peps.python.org/pep-0668/ is the latest piece of this.
I feel like this principle could be codified as "the system is not a workspace."
The use of the system as a workspace goes back to when computers were either very small and always personal only to one user, or when they were very big and administrated by dedicated system administrators who were the only ones with permission to install things. Both these conditions are obsolete.
