>You should point the finger at package managers. They never really addressed needs outside of system administration (to be fair, that's the problem they were trying to solve). Scripting languages came up with their own package system because package managers didn't fit their needs

I argue that's simply not true. Scripting languages came up with package managers because the largest platform (Windows) does not have a package manager. Actually that scripting languages implement package managers is a very good argument that their functionality is desired. As a side note, every language package manager is much worse in my experience than all of the system package managers I ever used.
