[duped]

There really aren't that many languages out there trying to be on the cutting edge of JIT for scientific computing with a great REPL experience. There are a few areas where developers have to prototype in a language like Python or MATLAB to design their systems, generate test data, and even just plot stuff during debugging then rewrite in C/C++ for speed. It's an enormous time sink that is prone to errors, and leads to terrible SWE culture.

If Julia can provide both the REPL/debugging experience of a language like Python or MATLAB with a fast enough JIT to use in production it would be an enormous boon to productivity and robustness.

There are a few limiting factors but I don't think they're absolute.
