@maegul @programming Perhaps this is all kind of like evolution: something that evolves to be sufficient doesn't necessarily need to further evolve to some pinnacle (however that may be defined it its context). R and Python are imperfect in so many ways, but sadly it gets the job done for most folks. I think people who explore Julia are simply not content for one reason or the other with R and Python (perhaps also Matlab), but they likely have gotten a lot of work done with R & Python.
