> performance is mostly good enough across all languages Performance of applications written in Python is good enough only were there is a very low requirement for fast code (e.g. glue code / shell replacement of which there is a lot and, as computers get faster, more and more) or there are native code libraries (e.g. numpy). Of the popular languages, only Ruby is slower. I have high hopes for Julia (at least in the data science / numerical computing domain) which performs much better, while preserving readability and ease of use of Python.
