People can write slow code in any language ;-) We've had to fire contractors who "wrote" dataframe code but was not vectorized in practice despite repeat request to do so. Same thing for slow code in CUDA. From a maintenance view, I much prefer folks write vectorized data frames vs numpy or low level bindings, but that comes from having lived with the alternative for a lot longer. All of our exceptions are pretty much slotted for deletion. (Our fast path is single or multi-GPU dataframes in python.) Here's to hoping that one day we'll have dependent types in mypy! |

That was a lot of my curiosity, because I'm not quite a good enough programmer to know whether the problem is just that the original code is bad or does something super inefficient, and so rewriting it any language will let you make massive improvements.
