Python is surely nice looking, but as it allows redefinition of everything at runtime, it is impossible to optimize at compile time. I think PHP, with the recent type strictness functionality, is better positioned for making way to new developments like meaningfull code analysis, (compile time) optimizations and performant JIT compilers. Python is too dynamic for that, unfortunately. The same holds for JavaScript.
