The reasons in the article might be valid for this particular company, but in my experience, the performance aspect is less valid in 90% of applications.

Either, the database is the limiting factor (and thus, languages like Python are fast enough, anyway) or the really performance demanding parts are located in <5% of the coding.

In my case, I enjoy the productivity that Python gives me and if I encounter such cases, that demand very high performance, I implement them in C or with Cython (or both).
