I was stating an opinion based on my experience. I don't deny that tools like SciPy are very useful for experimental programming. However SciPy and Matlab are exceptions, where the end-user of the program is also the programmer, so the developer experience IS the user experience.

In most cases, when you are a professional developer, you are not the end-user of your product. In these cases, deliberately choosing a less performant language for the sake of developer productivity can mean you end up penalizing the end user.
