It reduces software development costs, allowing more software to be written. There is plenty of software that needs to be written that doesn't exist today. Reducing costs helps with that need. The other side of that is software that already exists, running in the background unnoticed. Things like your graphics driver. You wouldn't want that written in Java. If it were written in Java you might get a lot of features faster, but it sure would perform like crap. For core software like that, development costs are secondary. Performance matters first. At the end of the day I think we need projects like neovim and oni. Editors are old technology and should be core software. Performance in my editor matters. I have five different IDEs installed and I still use vim.
