@dekkzz78 @tom_dalling if I understood the question, from my viewpoint Ruby is pretty universal tool. Web based apps are future - no doubt on that (at least GUI ones). However judging from other developments today there is way more data science usage than actual web usage. So I guess if Ruby finds its way into data area it will continue floating. I think Rails made Ruby known and useful to wide audience, but this was in the same time a curse - diminishing focus on other uses.
