If we could reboot all of computer science, I'd want one unified cross platform package manager with the same market takeover level as Git, and all languages designed to be aware of it. No file system overlay stacking or anything, no file system hierarchy of different folders for different types of resources, just python style search paths and virtual environments, and no global environment allowed, ever. But Python development is pretty nice at the moment so I can't complain.
