It isn't entirely untrue. Ruby/Python are more popular in the hobbyist space and less so in the enterprise. Java is the opposite.

It shouldn't be seen as a reflection of the platform.

You have set up a false dichotomy here between enterprise and hobbyist.

Does the scientific computing community count as hobbyist? It seems to be a significant niche for python these days, largely due to numpy.

Also, as another user noted, hobbyist/enterprise is a false dichotomy. There's shedloads of non-hobbyist code that also non-enterprise.
