That's fine; I don't think this is the general point. If you're trying to run a production system, need incredible robustness guarantees that somehow Julia cannot meet (which would be surprising to me), and require some specific things that Julia doesn't have, then sure, use Python. I'm just saying that, if you're a numerical scientist or engineer, go take a look at Julia and for most of these people it'll do everything and more than what they need. There will always be the pains of switching from one language/ecosystem to another and I'm not saying the tradeoff is worth it for everyone, but, if you can get development and performance speed up for a small tradeoff in learning curve, then I think it's worth at least trying it out, no? EDIT: The parent post was edited somewhat (which means this comment and some siblings appear slightly out of place) and I heavily disagree with a lot of the issues raised. I will keep the current comment as is for the sake of completeness, but I think the parent's approach to criticizing Julia is somewhat disappointing.
