Re: RDF.ex

Regarding the syntax and the capabilities for DSLs I also agree, but I wouldn’t consider these benefits a substantial technical advantage, which would justify redoing the enormous amount of work done in the Python world in these fields. What would companies or academic institutions who have invested in these tools get above some nicer syntax? 

Essentially there is only a difference in the underlying philosophies of the languages. Although Rubys philosophy also speaks much more to me too, I could also imagine that Python's philosophy (<https://www.python.org/dev/peps/pep-0020/>) speaks more to the scientists active in the fields in question, to many of whom the language is nothing more than a necessary tool, which should get out of their way. So they use what they are trained in and believe most of their peers want to use.

There will always be passionate developers, who care about the language so much, that they better invest time in reimplementing these tools in the language of their choice in their free time, but IMO this won't be enough, to catch up with the actual drivers in these fields, which are companies and academia.

But let me be clear: I would also be happy if more tools in these fields were available in Ruby than Python, but I don’t believe that this will happen realistically. Although I now would prefer Elixir and would argue, that it indeed would have real technical advantages to offer, I am even doubtful for Elixir.

Despite all of that, these resources might be of interest for you:

If we can leverage things such as DSLs and so on, at which Ruby is very good, then it may be possible to get an advantage on Python in some of these fields.
