* My entire codebase Julia has great interoperability between Python (checkout PyCall.jl) and many other languages. You don't need to abandon your old codebase. With regards to your other points, a lot of that is subjective and hard to argue about, but for me Julia has drastically changed the way I approach writing scientific code and is not just an incremental improvement upon the status quo.
