Note: not an expert or data scientist this could be an uninformed opinion. R has multithread support: https://josephcrispell.github.io/2018/08/27/multi-threading-R.html https://josephcrispell.github.io/2018/08/27/multi-threading-... Julia's main draw was native really fast code with multi-thread/parallel support. The other issue is that a parallelized c version of a data science algorithm can be scripted by Python or R pretty easily.
