I don't think interactivity and performance are enough to make a good production language. For example, I find Java painful to write without a good IDE, because of all the boilerplate, however it's that boilerplate that makes it very easy to read and refactor.
Agreed. They have to have a good way to write it (an IDE), a good debugger, a good profiler, a good library ecosystem, a good community, a good deployment story, reproducibility, portability across platforms, etc. I find commercial support helpful as well. Common Lisp has all of that.
