I heard a talk from a large cybersecurity company that was using Julia for research and is apparently in the process of dropping Julia due to: - difficulty in hiring, apparently it was too expensive/difficult to hire Julia programmers, - poorly performing garbage collector. If I recall correctly, they had issues when trying to process huge amounts of data.

Seems like small teams will not run into these issues at least initially.

I really like Julia and I hope it becomes huge, but stories like this make me wonder whether the whole Julia ecosystem will ever mature to a level of Python for example. And in turn, making it viable for large organizations that might be using e.g. Python + C++ combo that might be easier to hire for/more versatile/with better known drawbacks.

Essentially, I am not sure whether the potential of Julia is that much greater than the realized potential of the incumbents to warrant the "Julia is the language of the future".
