I disagree. We don't have enough incremental improvements, because it's difficult to improve a language and migrate the existing code base at the same time. I'd be happy with a better C (for example get rid of header files and #include), a better Python (for example better parallelism without a GIL), a better Go (for example with a solution for generics and marginally less verbose error handling), a better JavaScript, etc. I'm mentioning "mainstream" languages on purpose.
